Homoporus sinensis , new species

( Figs. 9-11 )

Material examined. – Holotype - female, IZCAS: CHINA: Hunan, Taojiang (28.5 N, 112.1 E), 7 Jul.1973, ex Loudonta dispar (Kiriakoff) ( Lepidoptera : Notodontidae ) coll. Tong Xin-Wang.

Paratypes - 25 females, 18 males, same data as holotype (2 females, 2 males NHM; 1 female, 1 male ZRC) ; 1 female, IZCAS: CHINA: Hunan: Hengshan , 7 Sep.1980, coll. Tong Xin-Wang ; 1 female, IZCAS: CHINA: Hunan: Nanyue Mt. , 8 Sep.1980, coll. Tong Xin- Wang .

Description. – Female. 2.48-3.5mm. Head and thorax dark green, gaster brown, slightly yellow centrally; antennae yellow; legs yellow except hind coxa brown.

Head in front view ( Fig. 9 ) with face reticulate and pilose; punctures in upper face larger than those on lower face; clypeus vertically striate, lower margin broadly truncate; mandible 3-toothed. Antennal insertions in the centre of face, scape reaching lower margin of median ocellus. Antenna ( Fig.10 ) with 2 anelli, first anellus longer than broad, second anellus subquadrate; each funicular segment longer than its breadth; apex of clava pointed; flagellum and pedicel combined slightly shorter than head width (0.88-0.92x width of head). Relative measurements: head width 66, height 50, dorsal length 29, POL:OOL 13:12, front width between eyes 41, eye height 31, malar space 13, distance from antennal toruli to median ocellus 24, distance from antennal toruli to clypeal margin 17.

Thoracic dorsum convex, with coarse reticulation; pronotum narrower than mesoscutum; notauli incomplete; frenal line only distinct on both sides of scutellum; propodeum finely reticulate, median carina absent, plica complete, propodeal nucha inconspicuous. Fore wing setose outside speculum; basal vein and basal cell setose, basal cell closed posteriorly. Gaster 1.33-1.79 x as long as broad. Relative measurements: pronotum width 46, collar length 4, mesoscutum 29: 52, scutellum 27: 30, marginal vein 38, postmarginal vein 34, stigmal vein 16.

Male: 2-2.4mm. Fore wing with brown setae; antenna and leg yellow; petiole with a distinct protuberance on both sides ( Fig.11 ). Antenna with flagellum plus pedicel combined 0.84- 0.95 x the width of head. Gaster 1.35-1.6 x as long as broad.

Etymology. – The species name refers to China.

Remarks. – Homoporus sinensis is close to H. japonicus Ashmead , both of them with the antenna having the first anellus longer than broad, second anellus subquadrate. H. sinensis differs from H. japonicus as follows: clypeal margin truncate, without sharp teeth; each funicular segment longer than broad; marginal vein about 2.1 x as long as stigmal vein; fore wing without brown infuscation. But H. japonicus with 2 sharp teeth on clypeal margin, 1 st – 2 nd funicular segments longer than broad respectively, 3 rd – 6 th funicular segments quadrate, fore wing with brown infuscation, marginal vein 1.6 x as long as stigmal vein,.

Host(s). – Loudonta dispar (Kiriakoff) ( Lepidoptera : Notodontidae ).

Distribution. – CHINA (Hunan).
