Introduction

Notosemus Forster, 1869, belonging to the tribe Oedicephalini of the subfamily Ichneumoninae

(Hymenoptera: Ichneumonidae), comprised five species until now (Yu et al. 2012), of which one is

from the Western Palaearctic Region (Kazmierczak 2004; Perkins 1959; Rasnitsyn & Siytan 1981;

Riedel et al. 2005), one is from the Eastern Palaearctic Region (Gokhman 1993), and three are from

the Oriental (Cameron 1903; Gupta 1987; Kusigemati 1986; Tosquinet 1903; Townes et al. 1961). One

species, N. polyambonios Kusigemati, 1986, was previously known from China (Kusigemati 1986). The

European Journal of Taxonomy 209 : 1-19 ( 2016 )

diagnostic characters of the genus were described by Kusigemati (1986). Prior to this publication the

hosts of Notosemus , and of the tribe Oedicephalini, were unknown.

In this paper, three new species, collected from Xizang Autonomous Region, SW China, and Jiangxi

Province, S China, and one new Chinese record, reared from Zeiraphera griseana (Hiibner, 1789)

(Lepidoptera, Tortricidae) from Ningxia Hui Autonomous Region, NW China, are reported.

Material and methods

The cocoons of the host, Zeiraphera griseana (Hiibner, 1789), were collected, brought to the laboratory

and maintained in culture dishes at room temperature by Prof. De-Jia Li (Forestry Pest Control and

Quarantine Station of Ningxia Hui Autonomous Region, China). The emerged insects were collected

daily.

Types of Notosemus albimaculatus Sheng & Sun, sp. nov. and N. planus Sheng & Sun, sp. nov., described

here, were collected by Dr. Tao Li with entomological nets in the forest of Xizang Autonomous Region.

The specimens from Wugongshan National Natural Reserve, Jiangxi Province, were collected with

intercept traps (IT) (Li et al. 2012) by Dr. Yan-Ping Liang.

The holotype of Notosemus inornatus Gokhman, 1993, and specimens of A. bohemani (Wesmael, 1855),

deposited in the Zoological Institute, Russian Academy of Sciences, St Petersburg, Russia (ZIR), and

the holotype of A. variegatus (Tosquinet, 1903), deposited in the Institut Royal des Sciences Naturelles

de Belgique (IRSNB), were studied. Photos of the holotype of A. polyamboniosi, for comparison with

Chinese specimens, were taken by Dr. Kyohei Watanabe, Kanagawa Prefectural Museum of Natural

History, Japan.

Images were taken with a Leica M205C stereo microscope equipped with LAS Montage MultiFocus.

Morphological terminology is mostly based on Gauld (1991).

All types and specimens, except those mentioned above, are deposited in the Insect Museum, General

Station of Forest Pest Management (GSFPM), State Forestry Administration, PR. China.

Remarks

This new species is similar to N. polyambonios Kusigemati, 1986 and N. albimaculatus Sheng &

Sun sp. nov., but can easily be distinguished from N. polyambonios by tergite 5 (Fig. 34) slightly

shagreened, with sparse, fine punctures, apical margin with very small median membranous area;

tergite 5 of N.polyambonios smooth, with very large median membranous area. This new species can

be distinguished from N. albimaculatus sp. nov. by the following combination of characters: tergites 2

(Fig. 33) approximately 1.7x as long as apical width; metapleuron with large median white spot; apical

margin of tergite 5 with very small median membranous area; hind tarsomere 1 apically, 2—4, and

tarsomere 5 basally white. N. albimaculatus sp. nov.: tergite 2 (Fig. 8) approximately 2.lx as long as

maximum width; Metapleuron entirely blackish brown; hind tarsus brown.

Discussion

The holotype of Notosemus variegatus (Tosquinet, 1903) (Fig. 26), a female specimen deposited in

IRSNB, was checked. In his description, Tosquinet (1903) recorded it as a male.

The new species, N. planus Sheng & Sun, sp. nov., agrees for the larger part with the definition of

Notosemus as defined by previous authors (Forster 1869; Kusigemati 1986; Townes et al. 1961), except

that the areolet is pointed above and the antennal flagellum is apically, ventrally flattened, and proved

very difficult to place in any genus. The first two authors and Tao Fi, the members of our research group,

have explored Xizang, Xinjiang, Jiangxi, Guangdong, Anhui, Guangxi, Guizhou, etc., in the Oriental

part of China, for years, and only the specimen of N. planus Sheng & Sun sp. nov. was collected. It

can easily be distinguished from other species of the genus by the unusual characters of the areolet and

antennal flagellum.

In China, species of Notosemus may be found only at high altitudes, above 1000 m. All specimens,

collected in Wugongshan, Jiangxi Province, were gathered by means of yellow intercept traps, which

indicates that perhaps Notosemus may be attracted by the color yellow.
