( Figs 13−16 )

Copidosomopsis trisegmentis Xu in Xu & Wu, 2000: 501 −504. Holotype Ƥ, ZJU (Zhejiang University), examined by ZYZ.

Copidosomopsis trisegmentis Xu : Zhang & Huang, 2004: 85.

Description. Female. Body length 0.8−0.9 mm. Body dark brown, with slight bluish green sheen; antenna dark yellowish-brown to dark brown, but about apical half of scape paler ventrally; tegula dark brown; fore and hind legs dark brown except bases of femora and apices of tibiae, and basal 4 tarsal segments yellow; mid leg ( Fig. 15 ) dark brown, except apex of femur, inner side and apex of tibia, and basal 4 tarsal segments yellow.

Head. Head in dorsal view about 1.8× as wide as frontovertex; ocelli forming an angle of about 120º; antenna ( Fig. 13 ) with scape about 5.5× as long as broad, F1 about as long as broad, F2−F6 slightly broader than length; clava 3-segmented, obliquely truncate at apex, the truncated part occupying half clava length.

Thorax. Mesoscutum with raised sculpture of polygonal cells, scutellum with sculpture shallower than mesoscutum; fore wing nearly 2× as long as broad (88/45), venation as in Fig. 14 .

Gaster. Ovipositor slightly exserted, the exserted part at most 1/10 gaster length.

Relative measurements: HW 36, FW 20, OOL 2, OCL 2, OD 3, MT 32, OL 30.

Male. Similar to female except antenna ( Fig. 16 ) and genitalia. Antenna dark brown; all funicular segments slightly wider than long except F1 sometimes a little longer than wide; clava apically pointed.

Host. Hapsifera barbata (Christoph) ( Lepidoptera : Tineidae ) ( Xu & Wu 2000); Euzophera batangensis Caradja ( Lepidoptera : Pyralidae ) (new host record).

Distribution. China (Beijing, Hebei, Shandong).

Material examined. CHINA, 60 Ƥ, 2 33, Shandong, Linyi, 20.v.1963, ex. lepidopterous larvae on peach, coll. XQ Xing; 23 Ƥ, 3 33, Beijing, Xi Shan, v.1976, ex. lepidopterous larvae on apple, coll. JW Bai; 24 Ƥ, Hebei, Qing Xian, v.1990, ex. Euzophera batangensis Caradja , coll. SM Song.

Comments. Copidosomopsis trisegmentis is similar to C. indica ( Kazmi & Hayat, 1998) and C. plethorica ( Caltagirone, 1966) , and particularly to C. indica in general color, antennal structure and sculpture of thorax. Further study may show that these two species should be considered synonymous.
