Coelopisthia condensus, Jiao & Xiao, 2014

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 : 552-554

Coelopisthia condensus sp. nov. ( Figs 25–31 )

Female. Length 2.1–2.7mm. Head and thorax dark green ( Figs 27–28 ), gaster dark brown with metallic reflection. Antenna black brown except scape, pedicel and anelli yellow brown. Mandibles fuscous. Wings hyaline with veins yellowish brown. Legs yellowish brown except coxae concolorous with thorax, femur brown in middle section.

Head in frontal view ( Fig. 25 ) about 1.32 times as high as wide; head height 1.43 times of eye height, eye space 1.2 times of eye height; scrobe deep, not reaching lower anterior ocellus. Clypeal area smooth with superficially stiate; lower margin of clypeus shallowly emarginate with two obtuse teeth. Head in lateral view ( Fig. 29 ), face not distinctly protuberant at antennal insertion; malar sulcus distinct. Antenna insertion placed on lower ocular line; scape 0.9 times of eye height, not reaching lower margin of anterior ocellus; pedicel and flagellum combined slightly shorter than head width (0.9 times); pedicel 2.3 times of its width, first anellus transverse, second anellus quadrate; Fu 1 –Fu 3 quadrate, Fu 4 –Fu 5 slightly transverse, funicular segment bearing one row of longitudinal sensilla; clava 2 times as long as its greatest width; apex of the third claval segment with small area of micropilosity. Head in dorsal view 2 times as wide as long; POL 1.77 times of OOL; eye length 2 times as long as temple.

Thorax in dorsal view distinctly narrower than head width, head width about 1.33 times as long as mesosoma; mesosoma slightly convex in lateral view, 1.55 times as long as broad. Pronotum 0.88 times as wide as mesoscutum, collar short and not margined. Mesoscutum 1.8 times as wide as long. Propodeum ( Fig. 30 ) half-length of scutellum; median carina only distinct on the base part, at most 1/3 length of propodeum; plica complete; nucha separated from rest of propodeum by inverted V-shape carina; propodeal spiracles ellipse, about 3 times as long as wide. Fore wing ( Fig. 31 ) 2.22 times as long as wide, with slightly densely hairy; costal cell bare on upper surface and with a row of setae on ventral surface; basal vein and basal cell bare; speculum reaching half length of marginal vein; submarginal vein 2 times as long as marginal vein, marginal vein 3 times as long as postmarginal vein, postmarginal vein shorter than stigmal vein, stigmal vein 1.46 times as long as postmarginal vein.

Metasoma slightly longer than mesosoma; gaster ovate, 1.33 times as long as broad; Gt 1 about 1/3 length of gaster, hind margin of Gt 1 slightly protudent, other tergite with hind margin straight.

Male. Body length 2.0 mm; head and thorax blue green with metallic reflection, gaster dark brown; antenna pale yellow; legs pale yellow except coxae concolorous with body. Antenna with the first anellus transverse, the second quadrate, each funicular segment slightly transverse except Fu 1 longer than its width, Fu 2 quadrate; petiole short, gaster ovate (1.25 times as long as broad), Gt 1 about 0.44 times length of gaster.

Specmens examined. Holotype ♀, China, Guizhou, Guiyang, Huaxi (26°27ʹN, 106°40ʹE), 5 May 2002. coll. Yan-Zhou Zhang ( IZCAS) . Paratypes: 1♀, 1♂, same data as holotype ; 3♀, Sichuan, Wanyuan , 9 May 1980, coll. Guan-Gui Tian.

Diagnosis. The new species is similar to C. caledonica with the marginal vein 2 times as long as stigmal vein, postmarginal vein distinctly shorter than stigmal vein and gaster ovate, but can be separated from C. caledonica by the antennal insertion slightly protuberance, stigmal vein 1.46 times as long as postmarginal vein, Gt 1 about 1/3 length of gaster. In C. caledonica , antennal insertion strongly protuberance, stigmal vein 1.14 times as long as postmarginal vein, Gt 1 about 2/5 length of gaster.

Biology. Unknown.

Distribution. China (Guizhou, Sichuan).

Etymology. The specific name refers to the wing with relatively densely hairy.
