Abstract. A taxonomic revision of the New Caledonian species of Arsipoda Erichson, 1842 is provided.

This group includes 21 species, of which 14 are new to science: Arsipoda atra sp. nov., A. communis

sp. nov., A. doboszi sp. nov., A. elongata sp. nov., A. gomezzuritai sp. nov., A. gressitti sp. nov.,

A. longifrons sp. nov., A. montana sp. nov., A. paniensis sp. nov., A. povilaensis sp. nov., A. punctata

sp. nov., A. rutai sp. nov., A. transversa sp. nov. and A. wanati sp. nov. A key for the identification, with

figures of habitus, main diagnostic characters, and genitalia is supplied. The range of host plants for

these species is extraordinarily broad, and a significant number of them feed on pollen. Crepicnema

Scherer, 1969, close to Arsipoda , is also investigated and maintained as a separate genus, and the

following synonymies and combination are proposed: Crepicnemaparvula (Jacoby, 1885) comb. nov. =

Chaetocnema tenimberensis Jacoby, 1894 syn. nov., = Arsipoda salomonensis Bryant, 1941 syn. nov.

The phylogenetic analysis, including also A. bifrons Erichson, 1842 and Crepicnema , confirms some

trends in distribution patterns of the endemic New Caledonian fauna, and highlights the necessity of

further studies to clarify the relationships between Arsipoda and related genera.

Key words. Dichotomous key, new combinations, new species, Pacific Island, pollen feeding.

Introduction

New Caledonia as the setting for this study is noted as one of Earth's Biodiversity Hotspots ( AA.VV.

2011; Kier et al. 2009; Lowry et al. 2004; Mittermeier et al. 2004; Myers et al. 2000; Myers 2003;

European Journal of Taxonomy 230 : 1-61 ( 2016 )

Possingham & Wilson 2005). This area is characterized as a model for isolated islands, marked by a

high degree of faunal disharmony (Gillespie & Roderick 2002; Gomez-Zurita 2011), with relatively

few established genera that have had more opportunities to radiate and fill available niches, generating

a high degree of microendemism (D’Alessandro et al. 2014; Gasc et al. 2013; Grandcolas et al. 2008;

Nattier et al. 2013). The origin of New Caledonian biota is controversial, because there is evidence for

both an ancient Gondwanan origin - implying the persistence of at least some original Gondwanan land

masses now forming New Caledonian territory -, and a more recent, late Eocenic or Oligocenic origin -

that is based on the hypotheses of a total submersion of the territory during the Eocene (Espeland &

Murienne 2011; Jolivet & Verma 2010; Papadopoulou et al. 2013). The first hypothesis is compatible

with the presence of some supposed Gondwanan relicts explained by ancient vicariance events and

subsequent diversification; the second one implies only recent dispersal events at the origin of the biota

and can justify the disharmonic composition of many New Caledonian taxa compared with the fauna

of other Gondwanan landmasses (Gillespie & Roderick 2002; Gomez-Zurita 2011), as well as the high

degree of neoendemism (Nattier et al. 2012, 2013). The New Caledonian Chrysomelidae fauna has been

investigated by Jolivet & Verma (2008, 2009). It includes 138 described species in 41 genera with an

endemism rate of 83.2% at the species level (Jolivet & Verma 2009). However, as also Jolivet & Verma

(2008, 2009) pointed out. New Caledonia and the neighbouring south-eastern Pacific islands have been

only partly explored. Indeed, other recent papers (Beenen 2008, 2013; Gomez-Zurita & Cardoso 2013;

Gomez-Zurita et al. 2010; Samuelson 2010) increased the number of species for different taxa.

The Chrysomelidae is one of the largest phytophagous insect families and includes approximately

37 000^10 000 species (Biondi & D’Alessandro 2012). The monophyletic tribe Alticini is closely related

to the tribe Galerucini, both contained within in the subfamily Galerucinae (Bouchard et al. 2011). This

paper, in particular, deals with Arsipoda Erichson 1842, a genus now recognized as one of the notable

examples of chrysomelid radiation in New Caledonia. It is one of the 11 flea beetle genera (Chrysomelidae,

Galerucinae, Alticini) occurring in New Caledonia (Jolivet & Verma 2009). Currently, about 75 species

are included in this genus, which is centered in Australia and extended to New Caledonia, New Guinea

with associated smaller islands, and the Solomon Islands (Heikertinger & Csiki 1940; Gomez-Zurita

etal. 2010; Mohamedsaid 2004; Samuelson 1973; Scherer 1969; Seeno & Wilcox 1982). The diagnostic

characters and phylogenetic affinities of Arsipoda are not stable in the literature (see Gomez-Zurita

et al. 2010 for a summary); the examination of type material attributed to this genus and kept at the

British Museum of Natural History (London) and Bishop Museum (Honolulu) actually revealed that

many species differ greatly from each other and from the type species A. bifrons Erichson, 1842, thus,

in our opinion, some of them should be placed in different genera. Anyway, a complete revision of this

genus is beyond of the aim of this paper that, instead, wants to focus on the group of species occurring

in New Caledonia that we consider here as belonging to Arsipoda. The New Caledonian Arsipoda were

studied for the first time by one of us (Samuelson 1973), who described A. agalma Samuelson, 1973,

A. isola Samuelson, 1973, A. shirleyae Samuelson, 1973, A. yiambiae Samuelson, 1973 and A. evax

Samuelson, 1973. Later, Gomez-Zurita et al. (2010) added two new species, A. geographica Gomez-

Zurita, 2010 and A. rostrata Gomez-Zurita, 2010. All of them are from the main island of Grande Terre

(only A. evax has been collected on Belep Island), none is recorded either from the Loyalty Islands or

the Isle of Pines. In this paper, we provide new distributional data on the known species, the description

of 14 new species from the Grande Terre, and a dichotomous key to all the species. We also report

ecological information derived from label data, and investigate about pollen consumption by looking

for the presence of pollen grains in the gut of the examined specimens. We recognize the monobasic

Oriental genus Crepicnema Scherer, 1969 as being closely allied to certain species of Arsipoda. Seeno

and Wilcox (1982) also put the two genera close to each other, and some authors even recently referred

to Crepicnema tenimberensis (Jacoby, 1894) as Arsipoda tenimberensis (Jacoby, 1894) (Kimoto et al.

1984; Gomez-Zurita et al. 2010). Thus we analysed the taxonomic position of Crepicnema and include

its results in our analysis below.

Material and methods

Material examined consisted of more than 1550 dried and pinned specimens preserved in the institutions

listed below. Specimens were examined, measured and dissected using Wild MZ12.5 and Leica

M205C binocular microscopes. The dissections were aimed at the extraction of the median lobe of

aedeagus and the spermatheca, and at the recovery of pollen grains inside the gut. Photomicrographs

were taken with a Leica DFC500 camera and the Auto-Montage Pro 2006 software (license number:

15224*syn2459* 153a2112_maurizio_266836). Scanning electron micrographs were taken with a

HITACHI TM-1000. Geographical coordinates of the localities were reported in the format used in the

respective labels; coordinates and geographical information included in square brackets and reported in

decimal degrees (DD-WGS84 format) were added by the authors using the website of Google Earth. The

terminology used follows Doberl (1986), Furth & Suzuki (1994) and Suzuki (1988) for the spermatheca

(Fig. 1 IE); Furth & Suzuki (1998) for the metafemoral spring (Fig. 6F); for the median lobe of aedeagus

see Fig. 10E. The cladistic analysis of the morphological dataset was performed with aid of the program

TNT vl.l licensed to the Willi Hennig Society using the traditional search algorithm (‘Wagner trees’),

non additive characters and implied weighting method. According to Goloboff et al. (2008a, 2008b) and

Goloboff (2013), character weighting by implied weighting method was used in our analysis because

jackknife frequencies and other resampling measures are, for morphological data, clearly improved

when weighting against homoplasy. The K value (constant of concavity) was chosen by us with the aid

of the script ‘Impliedw’ proposed by Mirande (2009). The morphological dataset used for the analysis

includes 34 characters, of which 33 bi-state and 1 tri-state. Eighteen characters were derived from the

external anatomy and 16 from the genitalic structures (median lobe of aedeagus and spermatheca). We

analyzed 23 taxa, i.e., the 21 New Caledonian Arsipoda species, with Arsipoda bifrons Erichson, 1842

and Crepicnemaparvula (Jacoby, 1885), treated as outgroups.

Taxonomic notes

Arsipoda agalma is quite different from the other species, mainly for the deep and elongate frontal

grooves, generally continued to post-antennal region, and the weakly convex pronotum, with very large

and strongly impressed punctures on disc (Fig. 4A). Median lobe of aedeagus variable (Figs 8A-B): in

ventral view laterally generally parallel, or slightly narrower in apical third, with a thin median groove;

apex from triangular to strongly pointed; in lateral view median lobe from thin to rather thickset,

moderately curved; dorsal ligula elongate - from basal fourth to almost the apex of median lobe of

aedeagus - wide, but thinner in apical part. Spermatheca (Fig. 11 A) with rounded basal part; collum

elongate, about twice the apical part; ductus thin, with straight and elongate proximal part.

Figs IB, 6A, 8C, 11B, 14B

Diagnosis

Arsipoda atra sp. nov. shares a thickset and ovoid body with A. evax , A. povilaensis sp. nov. and A.

transversa sp. nov. (Figs IB, F, 2D, I). However, the new species can easily be distinguished from other

species by its black, non-metallic integuments, and wide and flat elytral interstriae. Genitalia are also

highly diagnostic (Figs 8C, G, 9E, 10A, 11B, F, L, P).

Etymology

The specific epithet is a Latin adjective that means black, dark.

Figs 1C, 4B, 6E(1), F, 8D, 11C, T, 14B

Diagnosis

Arsipoda communis sp. nov. is a bronze, strongly metallic species quite similar in sculpture and color

to A. montana sp. nov. It can be distinguishable by the less transverse pronotum and the more weakly

impressed pronotal transverse sulcus (Fig. 4B, E). Median lobe of aedeagus is also useful to discriminate

between the two species (Figs 8D, 9C).

Diagnosis

Arsipoda elongata sp. nov. shares the elongate antennae with A. gomezzuritai sp. nov., A. longifrons

sp. nov. and A. rostrata (LAN/LB: $ > 0.70, $ generally > 0.60) (Figs IE, 2A, F, 3C). However, it can

easily be distinguished from them by the elongate, laterally parallel elytra, and by the green metallic color.

Taxonomic notes

Arsipoda evax shares a thickset, ovoid body withH atra sp. nov., A. povilaensis sp. nov. and A. transversa

sp. nov. (Figs IB, F, 2D, I). It can be easily distinguished by the smaller size and the black, metallic

integuments, (A. atra sp. nov. is black, but not metallic; A. povilaensis sp. nov. is yellowish; A. transversa

sp. nov. is reddish). Genitalia are also clearly distinguishable (Figs 8C, G, 9E, 10A, 11B, F, L, P).

Median lobe of aedeagus (Fig. 8G) in ventral view laterally parallel; apex subtriangular, slightly rounded,

with generally elongate median tooth; ventral surface with a shallow median depression at apical third;

in lateral view median lobe clearly and regularly curved in basal 3 /4S and straight in apical %; dorsal

ligula short - from apical third to apical part of median lobe of aedeagus -, wide, apically thinner.

Spermatheca (Fig. 1 IF) with pyriform basal part; collum moderately elongate, about twice as long as

Taxonomic notes

Arsipoda geographica is, along w ith A. gressitti sp. nov. and A. shirleyae, one of the yellowish species

lacking external morphological characters that allow a reliable identification, even thought, geographica

generally displays elytral interstriae slightly more convex (Fig. 6B); pronotal antebasal sulcus more

deeply impressed (Fig. 6B); elytral suture and lateral margin often darkened (Fig. 1G). These species

can be distinguished by relying on the morphology of genitalia (Figs 8H-I, 91, 11G-H, O).

Median lobe of aedeagus (Fig. 8H) in ventral view thickset, laterally parallel, apically widely rounded,

with a thin median tooth laterally parallel and apically truncate; ventral surface with a deep median

groove in the middle third; in lateral view median lobe distinctly curved; dorsal ligula short, from half

length to pre-apical part of median lobe of aedeagus, triangular, with wide base. Spermatheca (Fig. 11G)

with large, pyriform basal part; collum elongate, thickset and wrinkled; apical part distinctly shorter than

collum; ductus short, thin, apically inserted.

Ecological notes

Collected in montane maquis, moss forest, rainforest, and gallery forest, mostly from 800 to 1400 m a.s.l.

Found on flowers of Zygogynum bicolor (Winteraceae). Gomez-Zurita et al. (2010) report molecular

evidence associating this species with the genus Ardisia (Myrsinaceae; following the APG III Classification,

this family is now included wit hin the Primulaceae). Pollen found in the gut of some specimens.

Diagnosis

This species is similar in shape, sculpture and often color to A. longifrons sp. nov. and A. rostrata

(Figs 2A, F, 3C). They all are distinguishable from the other Arsipoda species by the elongate antennae

(LAN/LB: 3 > 0.70, $ generally > 0.60) and the elongate frons with narrow frontal carina. The three

species can be reliably distinguished by the shape of their genitalia (Figs 9B, G, 10D, 11J, M, S).

Etymology

Figs 1H, 81, 11H, 15A

Diagnosis

Arsipoda gressitti sp. nov. is, along with A. geographica and A. shirleyae , one of the yellowish species

lacking ventral morphological characters that allow a reliable identification. These species can be

distinguished only by relying on the morphology of genitalia (Figs 8H-I, 91, 11G-H, O).

Etymology

Male patronym. Named after Dr. J. Linsley Gressitt (1914-1982), who devoted his energies to the

establishment, development and expansion of the Entomology Department of the Bishop Museum

(Honolulu).

Figs 2A, 9B, 11J, 15A

Diagnosis

This species is similar in shape, sculpture and often color to A. gomezzuritai sp. nov. and A. rostrata

(Figs 2A, F, 3C). They are distinguishable from other Arsipoda species by the elongate antennae (LAN/

LB: S > 0.70, $ generally > 0.60) and the elongate frons with narrow frontal carina. The three species

can be reliably distinguished by the shape of genitalia (Figs 9B, G, 10D, 11 J, M, S).

Etymology

The name is a Latinized word referring to the elongate frons of the species.

Figs 2B, 4E, 9C, 14B

Diagnosis

Arsipoda montana sp. nov. is a bronze, strongly metallic species, quite similar to A. communis sp. nov.

in sculpture and color. They can be distinguished by the more transverse pronotum and the more deeply

impressed pronotal transverse sulcus in A. montana sp. nov. (Fig. 4B, E). Median lobe of aedeagus is

also useful to discriminate between the two species (Figs 8D, 9C).

Figs 2D, 5A, 9E, 11L, 15B

Diagnosis

Arsipoda povilaensis sp. nov. shares a thickset, ovoid body with A. atra sp. nov., A. evax and A. transversa

sp. nov. (Figs IB, F, 2D, I). It can be distinguished by the yellowish integuments (A. evax is black and

metallic, A. atra sp. nov. is black, and A. transversa sp. nov. is reddish); compared to A. transversa sp.

nov., with which it can be more easily confused, it also displays a less transverse and less convex pronotum

(Fig. 5A, D). Genitalia are also clearly distinguishable (Figs 8C, G, 9E, 10A, 11B, F, L, P).

Figs 2E, 5B, 6D, 9F, 15B

Diagnosis

Arsipoda punctata sp. nov. is an easily distinguishable small, yellow species with a strongly punctate

pronotum. Species with similar strong punctuation (A. isola and A. rutai sp. nov.) are very different in

color: bronze, metallic in the case of A. isola , and very dark with greenish metallic lustre in A. rutai sp.

nov.; moreover, the pronotal punctuation is unevenly sized in A. isola. Genitalia are also clearly different

(Figs 9A, F, H, 111, N).

Etymology

The specific epithet is a Latin adjective referring to the strong pronotal punctuation.

Taxonomic notes

This species is similar in shape, sculpture and generally color to A. gomezzuritai sp. nov. and A. longifrons

sp. nov. (Figs 2A, F, 3C). They are distinguishable from other Arsipoda species by the elongate antennae

(LAN/LB: $ > 0.70, $ generally > 0.60) and the elongate frons with narrow frontal carina. The three

species can be reliably distinguished by the shape of their genitalia (Figs 9B, G, 10D, 11J, M, S).

Median lobe of aedeagus (Fig. 9G) in ventral view fusiform, with small median tooth; ventral surface

with shallow median groove; in lateral view median lobe slightly and regularly curved; dorsal ligula

Figs 2G, 5C, 9H, 11N, 14A

Diagnosis

Arsipoda rutai sp. nov. can be easily identified by the very dark color with greenish metallic luster, and

rather large, strongly impressed pronotal punctuation. Species with similar strong punctuation (A. isola

and A. punctata sp. nov.) are of a different color: light brown with evident bronze luster (A. isola), and

yellowish, slightly metallic (A. punctata sp. nov.); moreover, the pronotal punctuation is unevenly sized

in A. isola (Fig. 4D). Genitalia are also clearly different (Figs 9A, F, H, 111, N).

Taxonomic notes

A. shirleyae is, along w ith A. geographica and A. gressitti sp. nov., one of the yellowish species lacking

external morphological characters that allow a reliable identification. These species can be distinguished

by relying on the morphology of genitalia (Figs 8H-I, 91, 11G-H, O). Median lobe of aedeagus (Fig. 91)

in ventral view thickset, laterally subparallel, with narrower base; apical part widened, laterally rounded,

with large median tooth; ventral sulcus V-shaped, clearly impressed median groove; in lateral view

median lobe distinctly curved, with slightly sinuate dorsal and ventral sides; dorsal ligula from apical

third to almost apex of median lobe of aedeagus, basally widened, then clearly narrower. Spermatheca

(Fig. 110) with pyriform basal part; collum very elongate (as long as basal part); length of apical part

about half as long as collum; ductus short, apically inserted.

Figs 21, 5D, 10A, IIP, 15A

Diagnosis

Arsipoda transversa sp. nov. shares a thickset, ovoid body with A. atra sp. nov., A. evax and A. povilaensis

sp. nov. (Figs IB, F, 2D, I). It can be distinguished by the more transverse and more convex pronotum,

and the generally reddish integuments, sometimes with darker head and pronotum (A. atra sp. nov. is

black, A. evax is black and metallic, and A. povilaensis sp. nov. is yellowish). Genitalia are also clearly

distinguishable (Figs 8C, G, 9E, 10A, 11B, F, F, P).

Etymology

The name is a Fatinized adjective referring to the distinctively transverse pronotum of the species.

Ecology

It is increasingly evident that New Caledonian Arsipoda can utilize a broad range of plant associates

(some as possible larval food plants) and that pollen-feeding is included in adult feeding strategies

(Gomez-Zurita et al. 2010; Samuelson 1989, 1994).

We report plant associate data for eight species of Arsipoda and of these, seven are associated with

more than one botanical plant family. A. isola , so far, shows the greatest range with 9 families. In one

collection of A. isola taken on leaves of Gmelina neocaledonica (Lamiaceae), beetles were aggregating

on fresh leaves of new plants and these leaves included many active larval mines (observed by collector).

These reported plant associates belong to 14 orders and 16 families according to APG III Classification

System (Bremer et al. 2009): Anacardiaceae (Sapindales); Aquifoliales (Aquifoliaceae); Auracariaceae

(Pinales); Cunoniaceae (Oxalidales); Cyperaceae (Poales); Dilleniaceae (incert order in APGIII System

(Bremer et al. 2009)); Ericaceae, Primulaceae - now including Myrsinaceae -, Symplocaceae (Ericales);

Euphorbiaceae (Malpighiales); Fabaceae (Fabales); Lamiaceae (Lamiales); Myrtaceae (Myrtales);

Pandanaceae (Pandanales); Proteaceae (Proteales); Winteraceae (Canellales).

Pollen grains were found in the gut of 13 species of either sex, including species lacking plant

identifications. It is likely that most species of New Caledonian Arsipoda will be shown to eat pollen.

Mouthparts adapted for pollen uptake may show special modifications: e.g., long and dense setae on the

mandible inner lobe and outer margin, the maxillary galea and lacinia, and flat areas at the base of the

mandible for grinding pollen grains (Bienkowski 2010; Samuelson 1994). Mouthparts of A. shirleyae

(Fig. 7A-B) have long setae on the maxillae, but not on the mandibles, which have an inner lobe covered

by short and dense setae that may be used for pollen feeding; this species also lacks mandibular grinding

areas and that may explain the intact pollen grains in the gut. The mode of pollen digestion by these

beetles remains unknown (Bienkowski 2010; Samuelson 1994).

Taxonomy

Within the variability of Arsipoda from all areas, the New Caledonian species show a high degree

of similarity (Figs 1A-I, 2A-I, 3A-C). They generally possess the following features: 1) small size;

2) frontal tubercles absent (Figs 4A-F, 5A-F); 3) frontal grooves short, generally not continued anteriorly

to postantennal region (exceptions in A. agalmd) (Figs 4A-F, 5A-F); 4) antennomeres 1-2 quite more

globose than antennomere 3; 5) pronotal antebasal transverse sulcus generally present, variable from

weakly to distinctly impressed, laterally bounded by small dimples, sometimes elongate, but neither

clearly impressed nor clearly reaching the basal margin (Figs 4A-F, 5A-F); 6) pronotal lateral margin

= 1.65 mm; WE = 1.04 mm ; LP = 0.48 mm; WP = 0.82 mm; LAN =1.12 mm;

= 2.15 mm; LE/LP = 3.44; WE/WP = 1.27; WP/LP = 1.71; WE/LE = 0.63; LAN/

= 1.58.

D’ALESSANDRO R et al., Arsipoda Erichson, 1842 from New Caledonia

generally straight or concave (Figs 4A-E, 5A-E), distinctly convex only in A. paniensis sp. nov. and

A. yiambiae (Figs 4F, 5F); 7) inner edge of hind tibiae with an apical emargination with thickset spines

(Fig. 6E); 8) hind tarsi thin; 9) first metatarsomeres sub-rectangular, about as long as the remaining

four together (Fig. 6E); 10) metafemoral spring of the Psylliodes morpho-group (Furth & Suzuki 1998)

(Fig. 6F); 11) spermathecal morphology of Type A (Furth & Suzuki 1994, 1998) (Figs 11A-S). These

character states are different in A. bifrons Erichson from Australia (Figs 12A-E), type species of the

genus, which shows: 1) larger size; 2) frontal tubercles present; 3) frontal grooves clearly continued

anteriorly to the postantennal region; 4) antennomeres 1-2 not globose; 5) pronotum lacking the antebasal

transverse sulcus, but with latero-basal longitudinal striae clearly impressed and reaching the basal

margin; 6) lateral margin of pronotum distinctly convex; 7) inner edge of hind tibiae without any apical

emargination; 8) hind tarsi more thickset; 9) first metatarsomeres sub-conical, shorter than the remaining

four together; 10) metafemoral spring probably belonging to the Altica morpho-group (Furth & Suzuki

1998); 11) spermathecal morphology of atypical Type A though not of Type B-Galerucinae type (Furth &

Suzuki 1994, 1998).

Crepicnema Scherer, 1969 (Figs 13A-E) is a monotypic genus including the only species C. parvula

(Jacoby, 1885) comb. nov. (= Chaetocnema tenimberensis Jacoby, 1894 syn. nov. = Arsipoda

salomonensis Bryant, 1941 syn. nov.) widespread in Oriental and Australian regions (Blackburn 1896;

Bryant 1937; Heikertinger & Csilci 1940; Gruev 1982; Jacoby 1896; Medvedev 1993; Medvedev &

Romantsov 2013; Samuelson 1967; Scherer 1969; Weise 1917). It shares character states 2, 4, 5, 6, 7, 8,

9, 10 with New Caledonian Arsipoda (noted in the numeration above), and is obviously a close relative.

It is further distinguished from Arsipoda by the presence of a distinct emargination on the outer margin

of the hind tibiae (Fig. 13C) (Biondi 2002; Scherer 1969).

Phylogenetic analysis

To test the relationships among the New Caledonian species, we included as outgroups Arsipoda

bifrons , as a “typical” large species, and Crepicnema. Our parsimony analysis used 34 bi-state or tri¬

state morphological characters (see Appendix A). The strict consensus tree is reported in Fig. 16 (K =

2.66; Consistency Index (Cl) = 0.449; Retention Index (RI) = 0.488).

The New Caledonian species of Arsipoda are arranged in the tree as a monophyletic group supported by

a high jackknife value (87) (Fig. 16). Even though it is likely that they represent a natural group derived

from a possible isolated radiation, we need a phylogenetic analysis based on a broader dataset to assess

their actual monophyly. The position of A. agalma is notable due to its presence of a deep frontal groove

running to the upper ocular margin (Character 1 in Appendix A): the only character state also present in

the two outgroup species and not shared by A. agalma with its New Caledonian congeners.

A significant matter arising from this tree concerns the taxonomic position of the genera Arsipoda and

Crepicnema. Three alternative hypotheses can be proposed: a) the New Caledonian species of Arsipoda

are to be attributed to the genus Crepicnema ; b) the New Caledonian species of Arsipoda are to attribute

to a new flea beetle genus; c) the genus Crepicnema has to be considered a synonym of Arsipoda. For

now we prefer not to take any decision about these three possible hypotheses, leaving any definitive

interpretation until a suitable and more complete phylogenetic dataset will become available and the

taxonomic situation of the Arsipoda species from other geographic areas will be clearer.

Distribution

Most of the New Caledonian Arsipoda species are restricted to Grande Terre, the main island. Only

A. evax is known from a nearby island (Belep Island), cited by Gomez-Zurita et al. (2010). Thus far,

we have no records of Arsipoda from the Isle of Pines or the Loyalty Islands. Based on our data, the

distributions of the species in New Caledonia vary from more or less widespread, even though often

rare, to strictly microendemic, with a major number of species and a denser distribution in the Southern

part of the island (Figs 14A-B, 15A-B). We have to point out, however, that in New Caledonia there

are some logistic and cultural differences which make it easier to collect in the South Province; thus, the

distribution map may reflect a bias in the sampling activity (Gomez-Zurita pers. comm.). Nevertheless,

some trends in the distribution patterns of the New Caledonian fauna (Pellens & Grandcolas 2010) can

be deduced from these data: a) individual species are generally rare; b) short range endemism appears

more frequently as distributional studies accumulate; c) sister species apparently appeared by allopatric

speciation and are often separated by very short distances, even though some with a more disjunct

distribution have been considered as relicts in refuge areas. In our analysis, one of the three significantly

supported clades (Fig. 16) within the New Caledonian Arsipoda, [rostrata (, gomezzuritai, longifrons)],

links species all endemic to the South Province with partially overlapping or slightly isolated distributions

(Figs 14B, 15A-B). In this clade, we can recognize a pattern of endemism of the type II of Pellens &

Grandcolas (2010): short range endemic sister species with parapatric/allopatric distributions. The same

situation can be observed for A. geographica and A. shirleyae in the clade [ geographica, punctata,

shirleyae], even though the clade is unresolved and A. shirleyae has a slightly wider distribution; A.

punctata sp. nov. appears rather isolated from the other two species. A parapatric distribution can be also

seen between A. yiambiae and A. rutai sp. nov. and between A. rutai sp. nov. and A. transversa sp. nov.

within the unresolved clade [rutai, transversa, yiambiae]; in this case, A. yiambiae and A. rutai sp. nov.

display a relatively wide distribution rather than a “short ranged” distribution

The clade [wanati ( paniensis, povilaensis)] is different, in that it includes allopatric species attributable

to the pattern of endemism of type III of Pellens & Grandcolas (2010), characterized by related species

with disjunct distributions occurring also in the North Province.

Discussion

Our study, based on more than 1550 specimens of Arsipoda, tripled the number of known species of New

Caledonia from seven to 21, but may, nevertheless, still be regarded as preliminary. All these species are

macropterous, and they are potentially able to move easily; also they seem broadly adaptable regarding

food choice. Yet, some of these species are microendemic, being restricted to limited areas. These traits

accordingly invite further collecting, especially in hard to reach locations, and they also create a need for

general studies of their habits. So far, only one species of Arsipoda has been associated with an exotic

host. Arsipoda evax was collected on flowers of mango ( Mangifera indica ), denoting a shift to a new

host from native hosts of several diverse families. That event must have occurred quite recently, noting

that most Mangifera introductions to Pacific islands took place only over the past 100 years (Bally

2006). Additional species and data on their ecologies will certainly come to light, as further surveys are

conducted in the New Caledonia area, including the Loyalty Islands. Furthermore, expanding Arsipoda-

centered studies to surrounding areas will also help to clarify whether the New Caledonian elements are

truly monophyletic, and perhaps help to clarify the status between Arsipoda and Crepicnema.
