Copidosomopsis trisegmentis Xu

(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.
