Abstract. The genus Rhinotorus Forster, 1869 is revised. Thirteen species are recognized including

3 species that are new to science ( R. jussilai sp. nov., R. campester sp. nov., R. tarsilatus sp. nov.).

Saotis brachycerus (Kasparyan & Kopelke, 2009) comb. nov. is considered to be a member of the

genus Saotis. Rhinotorus similis (Brischke, 1892) is tentatively recorded from Austria and Sweden for

the first time. A number of new host records are also provided: Cladius pectinicornis (Geoffroy, 1785)

for A. leucostomus (Gravenhorst, 1829), Nematus lucidus (Panzer, 1801) for A. nasutus (Gravenhorst,

1829) and A. papillosus (Retzius, 1783) for R. jussilai sp. nov.

Keywords. Holarctic, new host records, parasitoid wasps, koinobiont endoparasitoid, Mesoleiini.

Introduction

Rhinotorus Forster, 1869 is a genus in the family Ichneumonidae (Hymenoptera), the most species-rich

family of Hymenoptera and one of the largest insect families (Townes et al. 1965). It belongs to the

tribe Mesoleiini, a large tribe in the subfamily Ctenopelmatinae with 25 genera. The subfamily includes

around 760 described Western Palearctic species (Yu et al. 2012; Kasparyan 2012, 2014; Reshchikov

2013, 2015).

Rhinotorus is predominantly a Palearctic genus. Prior to this study only 12 species were known, including

one species from the Nearctic Region (Yu et al. 2012). Nearly all ctenopelmatines are koinobiont

endoparasitoids of sawflies, and most records are from the largest family of sawflies (Tenthredinidae)

(Table 1).

Material and methods

This study is a part of 2 projects entitled “Ctenopelmatinae, a poorly known group of parasitic wasps

in Sweden” funded by The Swedish Taxonomy Initiative ( http ://www. slu. se/en/collaborative-centres-

Morphological terminology follows Gauld (1997) and Karlsson & Ronquist (2012). Unless indicated as

new records (marked by “*”), all distributional and host records in the sections “distribution” and “host

Type species: Spudea longicornis Schmiedeknecht, 1914; designated by Perkins (1962).

Diagnosis (updated from Townes 1970)

Small to moderate sized species, fore wing length 4.5-9 mm. Ground colour mainly black. Antenna

slender to stout, with 28-38 flagellomeres. Scape 1.25-1.6 times as long as broad. Face usually convex

and densely punctate. Clypeus small, convex, around 0.3-0.4 times as long as broad, distinctly separated

from face by a deep impression, medially projecting, shining and sparsely punctate, its apical margin

rounded, laterally impressed and sharp. Malar space 0.5-0.7 times basal mandible width. Occipital

carina complete. Mandible with teeth usually of equal length. Notaulus distinct. Mesopleuron usually

granulate, striated, or densely and coarsely punctate. Metapleuron wealdy shining, rugose, with rather

dense punctation in upper part. Propodeum strongly rugose. Area superomedia usually fused with area

basalis. Costula absent. Area apicalis large, trapezoidal, often with longitudinal carina and sometimes

with striation. Spurs of middle and hind tibiae of unequal length. Tarsal claws not pectinate. Fore wing

with pterostigma elongate. 2m-cu straight, with a single bulla. Cu-a vertical, slightly postfurcal. Hind

wing with 1/Cu & cu-a intercepted by 2/Cu in lower 0.5. Metasoma coarsely punctate and reticulate

rugose. First metasomal tergite usually short and projecting dorsally, its dorsal longitudinal carinae

reaching middle of tergite, with a strong impression between carinae in basal part. Subapical impression

strong. Second metasomal tergite with transverse impression starting immediately after middle of tergite.

Third tergite with weak transverse impression. Ovipositor sheaths weakly clavate. Ovipositor stout at

base with triangular shape before shallow subapical notch, its lower valvae slightly swollen before thin

tip and tip of upper valve rather elongate after notch. Parameres broad basally and weakly elongate

apically, extending beyond aedeagus. Volsella moderately large and notched apically. Aedeagus apically

downcurved.

Tribal diagnosis

The genus belongs to the tribe Mesoleiini, whose representatives can be distinguished from other

ctenopelmatines by combination of the following characters: epicnemial carina reaching fore edge of

mesopleuron, notch between basal part of propodeum (at its middle) and hind edge of postscutellum

V-shaped, glymma present, claws mostly without pecten.

Species in the genus Rhinotorus can be recognized by combination of the following characters: first

and second metasomal tergites with subapical transverse impressions. Metasoma strongly punctate and

reticulate rugose. Median dorsal carinae of first metasomal tergite distinct. 2m-cu with a single bulla.

Areolet absent. Glymma present. Hind wing with 1/Cu & cu-a intercepted by 2/Cu in lower 0.5.

Some representatives of other Mesoleiini genera also have subapical transverse impressions of

metasomal tergites [e.g., Mesoleius roepkei Teunissen, 1945 and Saotis brachycerus (Kasoparyan &

Kopelke, 2009) comb. nov. (Figs 1, 2C-D)], but these have a broad and short ovipositor sheath, or a

compressed metasoma as in Saotis (Fig. 1). Saotis brachycerus (Kasoparyan & Kopelke 2009) comb,

nov. originally was described in the genus Rhinotorus with note “ Saotis ” in the brakes (Kasoparyan &

Kopelke 2009). However it should be considered as Saotis since it has the ovipositor sheaths shortly

elliptic but not elongate cone- or club-shaped as in Rhinotorus.

Diagnosis

This species is distinguished from other species in the genus by the following characters: face tapering

downwards in anterior view (Fig. 3A); mesopleuron coriaceous, matt, and impunctate (Fig. 3B); hind

femur and basal tarsomere of hind leg slender (5.5 times as long as broad and 6.7 times as long as broad,

respectively); transverse impression of first metasomal tergite not defined (Fig. 3E); face and scutellum

black; metasoma red centrally (Fig. 3E).

Discussion

I was unable to include R. latvicus (Ozols, 1928) in this revision as the type material (deposited in the

private collection of Arvids Ozols) was not available for study. According to the original description,

this species is possibly a junior synonym of R. similis (Brischke, 1892).

Another species with unclear taxonomic status is R. clypearis (Brischke, 1888), originally described in

the genus Trematopygus Forster, 1854, but as no material of this species was available for examination,

it was not included in this revision.

Saotis brachycerus (Kasoparyan & Kopelke 2009) comb. nov. (originally described in Rhinotorus ) is

considered to be a member of the genus Saotis due to the form of the ovipositor sheaths which are

shortly elliptic and not elongate cone- or club-shaped as in Rhinotorus.

Representatives of the genus are rather rarely collected and very few specimens are present, even in

the huge collections of the larger European museums. Thus only 13 species of the genus are presently

known including the 3 new species described here.

Rhinotorus similis (Brischke, 1892) is tentatively recorded from Austria and Sweden for the first time.

The following sawflies are recorded here as new hosts for the genus: Cladius pectinicornis (Geoffroy,

1785) for R leucostomus (Gravenhorst, 1829) and R. similis (Brischke, 1892), Nematus lucidus (Panzer,

1801) for R nasutus (Gravenhorst, 1829) and Nematuspapillosus (Retzius, 1783) for R. jussilai sp. nov.
