Figs 3, 11, 18

Lecithocera callirrhabda Meyrick, 1936: 158. TL: China (Yunnan). TD: NHMUK.

Opacoptera callirrhabda (Meyrick): Gozmány, 1978: 179.

Material examined.

China: 1♀, 30.vii.2014, 3♂, 2-3.viii.2014, Yunnan, Dali, Mt. Weibao, 2205 m, KJ Teng et al. leg., slide nos. YS19428 ♂, YS19435 ♀.

Diagnosis.

This species is diagnostic in the male genitalia by the juxta incised at middle in a triangle on the posterior margin (Fig. 11). It is similar to O. condensata sp. nov., and the differences between them are stated in the diagnosis of the latter species.

Description.

Wingspan 13.5-15.0 mm (Fig. 3).

Female genitalia (Fig. 18). Eighth abdominal sternite obtuse on posterior margin. Apophyses posteriores twice length of apophyses anteriores. Antrum cup-shaped, wrinkled, membranous except sclerotized along posterior margin forming a band. Ductus bursae subelliptical, slightly wider than corpus bursae, partly wrinkled anteriorly; ductus seminalis broad basally, slender distally. Corpus bursae elliptical; signa placed medially, consisting of five teeth in a longitudinal row and a small rounded, denticulate plate.

Distribution.

China (Sichuan, Yunnan) ( Gozmány 1978; Wu 1996).

Remarks.

Meyrick (1936) described this species based on five male specimens (one from Shandong, two from Shaanxi and Yunnan, respectively) and placed it in the genus Lecithocera . Clarke (1965) assigned one of the specimens from Yunnan as the lectotype according to the original description. Gozmány (1978) noted that only the two specimens from Yunnan were conspecific. He also hypothesized that they were distinct from Lecithocera, so diagnosed the genus Opacoptera and placed the species therein. Wu (1996) was first to described the female of O. callirrhabda based on specimens with associated males collected at different times and from different localities of Sichuan. According to the description and the drawing given by Wu (1996), the female genitalia of O. callirrhabda has a narrowed ductus bursae and a single signum. However, the female of the species examined in this study from Yunnan is quite different, and we describe it herein.
