Material examined.

1 female, 30.VII.2003, Jiuwanshan Natural Reserve, Rongshui Miao Autonomous County, Liuzhou, Guangxi Zhuang Autonomous Region, leg. Min Wang; 1 female, 9.VI.2014, Deqin County, Diqing Tibetan Autonomous Prefecture, Yunnan Province, leg. Jia-qi Wang.

Diagnosis.

Psychostrophia endoi is closely related to P. picaria Leech, 1897 from central and western China in external features, but it can be distinguished from it by the following combination of characters: on forewing upper side the postmedian band forming two obviously connected teeth in cell M3 and CuA1, pointing to termen in both sexes; the submarginal spots absent in male and the submarginal band below the subapical spot weak and represented by separated minute white dots in female; on hindwing upper side the postmedian band is obsolete and represented by white dots in male and the postmedian band ill-developed and represents by separated white dots in female; in male the genitalia valva more protruding at apex; in female genitalia the lamella antevaginalis is trapezoid in ventral view.

Description.

Length of forewing 21-22 mm, female differs from male in larger size and having submarginal series on both wings better developed. Head black; antenna filiform, black; forewing ground color black, cilia black from apex to vein R5, white from R5 to median portion of cell M1 and becoming black again from median portion of cell M1 to tornus; postmedian band white, extending from middle of the cell M1 to dorsum, with its inner edge wavy and outer edge forming two prominent connected tooth in cell M3 and CuA1; subapical spot white and well-developed, oval shape; submarginal band consisted of four or five separated white dots situated from cell M1 to cell CuA2; hindwing ground color black, cilia black from apex to vein M1, white from M1 to median portion of cell M2 and becoming black again from median portion of cell M2 to tornus; median band white and broad, becoming wider towards costa; postmedian fascia consisted of separated white dots of different size running from apex to tornus.

Female genitalia (Figs 27, 28). Papillae anales slightly sclerotized, elliptical in lateral view, with tip rounded. Apophyses posteriores and anteriores slender; and the latter are slightly shorter than the former. Antrum well-developed and forming a strongly sclerotized chamber. Ostium bursae nearly the same width as antrum. Lamella antevaginalis strongly sclerotized, rectangular in lateral view and trapezoid in ventral view, with edge shallowly concave in the middle. Lamella postvaginalis slightly sclerotized and poorly developed, horn-shaped in lateral view. Ductus bursae membranous, long and curved medially, its anterior part near the corpus bursae slightly sclerotized and pigmented. Corpus bursae membranous, large and oval shape, scobinated with numer ous small spines; its dorsal ridge near ductus bursae sclerotized and pigmented; next to the sclerotized ridge a sclerotized signum presents, consisting of larger spines.

Remarks.

The female of P. endoi (Figs 25, 26) is recorded here for the first time. This little known species has not been recorded elsewhere after Inoue described it in 1992 from northern Laos. The differences in the sizes of the submarginal series between females and males ( Inoue 1992: fig. 1), due to sexual difference, is rather common.

Biology.

The flying period of this species is from early June to late July. The male (Fig. 29) of this species could be found sucking nutrient on wet ground on road of farmlands near evergreen broad-leaved forest (Fig. 30).

Distribution.

China*(Yunnan, Guizhou, Guangxi), Laos (Sam Neua).
