Andrioplecta pulverula (Meyrick, 1912)

(Figs. 4, 9, 15)

Laspeyresia pulverula Meyrick, 1912: 876 . Type locality: India (Assam, Khasi Hills). Holotype (♀): BMNH. Andrioplecta pulverula Obraztsov, 1968: 177 .

Material examined. Hainan: 1 ♂, Nancha, Bawangling, 600 m, 6.vi.2007, leg. Zhiwei Zhang and Weichun Li. Henan: 1 ♀, Zushiliulou, Gushi County, 120 m, 16.v.1995, leg. Guangyun Yan; 1 ♂, Lingshansi, Luoshan County, 350 m, 23.v.2000, leg. Haili Yu.

Diagnosis. Adult (Fig. 4) with wingspan 12.0−13.0 mm. This species is characterized by the forewing pattern which features a black submedian patch originating from the basal 1/3 of the dorsum. The male genitalia of A. pulverula are similar to those of A. oxystaura (Meyrick, 1935), but they can be distinguished by the aedeagus abruptly narrowed in distal 1/4 and absence of cornuti in the male genitalia (Fig. 9); and the ductus bursae about the same length as the corpus bursae in the female genitalia (Fig. 15). In A. oxystaura the aedeagus is abruptly narrowed in the distal 1/3 and bears four deciduous cornuti; and the ductus bursae is about 1/3 the length of the corpus bursae. Andrioplecta pulverula is also extremely similar to A. shoreae Komai, 1992, and the differences between them are noted under the latter species.

Hosts. The larvae have been found mainly galls of gall wasps ( Hymenoptera: Cynipidae) on Castanea and Quercus (Fagaceae), feeding on the larvae of gall wasps (Komai 1999).

Distribution. China (Anhui, Guangdong, Hainan, Henan, Jiangxi, Shandong, Sichuan, Yunnan), Japan, Korea, India.
