Copidosomopsis orientalis Yu & Zhang , sp. nov.

( Figs 1−6 )

Description. Female. Body length 0.8–1.0 mm. Body dark brown, head and thorax with purplish green sheen; scape yellow except dorsal margin at apex brownish, pedicel and flagellum dark brown; tegula dark brown; coxae of all legs dark brown; fore leg with femur except apex dark brown, tibia generally yellow except dorsal margin marked dark, and tarsus generally yellow except apex brown ( Fig. 3 ); mid leg with femur except apex dark yellowish-brown, tibia generally yellow but median part often brownish, tibial spur yellow, and tarsus generally yellow except apex brown ( Fig. 4 ); hind leg with femur except base dark brown, tibia yellow but subbasally often brownish, tarsus generally yellow except apex brown ( Fig. 5 ).

Head. Head in dorsal view nearly 2× as wide as frontovertex; ocelli forming an angle of about 100º; antenna ( Fig. 1 ) with scape about 5.5× as long as broad; pedicel about 1.2× as long as F1; funicular segments shortening distad, F1 about 1.5× as long as broad, F6 broader than long; clava solid, obliquely truncate at apex, the truncated part about half clava length.

Thorax. Mesoscutum with raised sculpture of polygonal cells, scutellum with same sculpture but apically smooth; fore wing about 2.2× as long as broad (80/36), venation as in Fig. 2 .

Gaster. Gaster about as long as thorax; ovipositor sheaths ( Fig. 6 ) slightly exserted.

Recognition. Copidosomopsis orientalis is similar to C. arenicola ( Trjapitzin, 1967) in general coloration and habitus. Copidosomopsis arenicola was originally described by Trjapitzin (1967) from Primor'ye Kray of Russia and redescribed by Kazmi & Hayat (1998) based on material from India. Based on the original description of C. arenicola , C. orientalis can be separated from C. arenicola by the postmarginal vein being absent ( Fig. 2 ) as compared to present though short in C. arenicola , basal cell of fore wing with more setae ( Fig. 2 ) than in arenicola (basal cell with sparse setae as in Fig. 8 ) and truncated part of clava occupying half its length ( Fig. 1 ) rather than ¾ its length as in C. arenicola .
