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.

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 .
