Jiao, Tian-Yang & Xiao, Hui, 2014, Taxonomic review of the genus Coelopisthia Förster (Hymenoptera: Pteromalidae) from China, with four new species, Zoological Systematics 39 (4), pp. 545-554 : 551-552

Coelopisthia pseudaletia sp. nov. ( Figs 20–24 )

Female. Length 2.0 mm. Body ( Figs 20–21 ) dark green. Antenna brown. Mandibles fuscous. Wings hyaline, veins yellowish brown. Legs yellowish brown except coxae concolorous with thorax.

Head in frontal view ( Fig. 22 ) about 1.24 times as high as wide; head height 1.52 times of eye height, eye space 1.25 times of eye height; upper face and lower face with densely raised reticulation; scrobe shallow, not reaching lower anterior ocellus. Clypeal area smooth with superficially stiate; epistomal sulcus distinct; clypeal margin protrudent and broadly emarginate. Head in lateral view ( Fig. 23 ), face not distinctly protuberant at antennal insertion, the angle of lower face with upper face more than 120°; malar sulcus indistinct; malar space 0.23 times of eye height. Antenna ( Figs 22–23 ) insertion slightly below lower ocular line; scape as long as eye height, not reaching lower margin of anterior ocellus; pedicel and flagellum combined almost as long as head width; pedicel 2.5 times of its width, first anellus transverse, second anellus quadrate; each funicular segment quadrate, bearing one row of longitudinal sensilla; clava 2 times as long

© Zoological Systematics, 39(4): 545–554 as its greatest width; apex of the third claval segment with small area of micropilosity. Head in dorsal view 1.83 times as wide as long; POL 2.1 times of OOL; eye length 2 times as long as temple.

Thorax in dorsal view distinctly narrower than head width, head width about 1.22 times as long as mesosoma; mesosoma slightly convex in lateral view. Pronotum 0.86 times as wide as mesoscutum, collar short and not margined. Mesoscutum 2 times as wide as long, notauli incomplete. Propodeum ( Fig. 24 ) 0.62 times length of scutellum; median carina only distinct on the base part, at most 1/3 length of propodeum; plica incomplete; nucha with surface transverse reticulation; propodeal spiracles ellipse, about 2 times as long as wide. Fore wing 2.3 times as long as wide; costal cell bare on upper surface and with a row of setae on ventral surface; basal vein and basal cell bare; speculum reaching base of stigmal vein; submarginal vein 2.5 times as long as marginal vein, marginal vein 3 times as long as postmarginal vein, stigmal vein, 1.5 times as long as postmarginal vein.

Metasoma distinctly shorter than mesosoma (0.83 times); petiole invisible in dorsal view; gaster circle, as long as wide, 1.21 times as wide as mesosoma; Gt 1 about 2/5 length of gaster, hind margin of each tergite straight.

Male. Body length 2.0 mm; head and thorax blue green with metallic reflection, gaster dark brown; antenna yellowish brown; legs yellowish brown except coxae brown. Antenna with two anelli transverse; petiole transverse, gaster ovate.

Specimens examined. Holotype ♀, China, Yunnan, Simao (22°48ʹN, 100°58ʹE), ex. Pseudaletia separate Walker, coll. Ding-Xi Liao ( IZCAS) . Paratypes: 4♀, 1♂, same data as holotype .

Diagnosis. The new species is somewhat similar to C. caledonica and C. condensus sp. nov. with the marginal vein 2 times as long as stigmal vein, postmarginal vein distinctly shorter than stigmal vein, but can be separated from C. caledonica and C. condensus sp. nov. by the gaster rounded and shorter than mesosoma, propodeum with plica imcompelet and middle area slightly depressed. In C. caledonica and C. condensus sp. nov., gaster ovate and at least as long as mesosoma, propodeum with plica complete and middle area not depressed.

Biology. Reared from Pseudaletia separate Walker ( Lepidoptera : Noctuidae ).

Distribution. China (Yunnan).

Etymology. The specific name refers to host of the species.
