Epitetracnemus comis; Trjapitzin, 1989: 486; Zhang & Huang, 2004: 64; Xu & Huang, 2004: 139.
Description. Female. Body length 1.0− 1.5 mm. Body dark brown with a metallic green or blue sheen; mesoscutum with green-blue reflections; scutellum with purplish reflections; antenna (Fig. 55) generally dark brown except apices of scape and pedicel, and F 6 yellowish, F 1 −F 5 yellowish-brown; fore wing with infuscate pattern as in Fig. 56; fore leg (Fig. 57) yellow except femur almost entirely and tibia dorsally dark brown, tarsus dark yellowish-brown; mid leg (Fig. 58) yellow except coxa, apical half of femur and subbasal band of tibia dark brown; hind leg (Fig. 59) yellow except coxa and subbasal band of tibia dark brown.
Head. Frontovertex width at anterior ocellus 1 / 5 − 1 / 6 head width; ocelli forming an angle of about 45 º; posterior ocellus touching inner eye margin, and separated from occiptal margin by 2 × its own diameter; antennal scape about 4 × as long as broad; F 1 −F 3 slightly transverse; F 4 −F 6 subquadrate; clava about as long as funicle (Fig. 55); mandible with two teeth and an upper serrate truncation (Noyes & Ren 1987, fig. 8).
Thorax. Fore wing (Fig. 56) about 2.5 × as long as broad; marginal vein conspicuously longer than stigmal vein; postmarginal vein short or nearly absent.
Gaster. Ovipositor sheaths (Fig. 60) slightly exserted, by 1 / 8 − 1 / 7 gaster length.
Relative measurements. MT 50, OL 70, GL 20.
Male. Generally similar to female except for antennae and genitalia (see Noyes & Ren 1987).
Host. Pseudaulacaspis pentagona Targioni-Tozzetti (Noyes & Ren 1987).
Distribution. China (Noyes & Ren 1987; Zhang & Huang 2004).
Type material examined. CHINA: Guangdong, Baiyun, 19.viii. 1984, ex. Pseudaulacaspis pentagona on Prunus persica, coll. H. Ren (holotype Ψ, IZCAS).
Non-type material examined. CHINA: Sichuan, Chengdu, 23.vii. 1963, ex. Pseudaulacaspis pentagona on Prunus persica, coll. D.X. Liao (5 ΨΨ); Chengdu, 10−11.vii. 1963, coll. D.X. Liao (12 ΨΨ, 2 ɗɗ). Zhejiang, Wuyan Ling, 3.viii. 2005, Coll. Y.X. Zhao (1 Ψ).
Comments. Recently, Li et al. (2002) described Epitetracnemus kosef Li & Byun from Korea, which is very similar to E. comis except the antennal clava is slightly longer.
