( Figs 10–11 )

Ricania pulverosa Stål, 1865: 162 ; Stål, 1870: 767; Atkinson, 1886: 61; Noualhier, 1896: 256; Schmidt, 1905: 176; Distant, 1906: 380; Schumacher, 1915: 130; Melichar, 1898: 240; Esaki, 1932: 1805; Kato, 1933: 7; Zia, 1935: 537; Lallemand, 1942: 70; Jacobi, 1944: 22; Chou et al., 1985: 81.

Ricanula pulverosa, Melichar, 1923: 130 ; Metcalf, 1955: 97; Yang, 1989: 193.

Specimens examined. 1 male: 1 Jun. 1974, Yunnan, Xishuangbanna, Mengla, coll. Yao Chou et Feng Yuan ; 1 male: 18 Apr. 1982, Yunnan, Xishuangbanna, Mengla, coll. Sumei Wang et Jingruo Zhou.

Measurements. Length (inc. tegmen): male 7.8 mm.

Remarks. First time after original description, Yang (1989) described and illustrated the male and female genitalia of the species based on Taiwan specimens. The morphological characters examined here are consistent with Yang’s (1989) description, but the male genitalia in this study show somewhat intraspecific variations as follows: 1) anal tube nearly rectangular in dorsal view ( Fig. 10G ) (irregularly hexagonal in Yang, 1989, Fig. 12G); 2) lateral processes of aedeagus reaching only 1/4 of the dorsal processes ( Fig. 10I ) (lateral processes reaching 1/2 of the dorsal processes in Yang, 1989, Figs 12H, I).

Distribution. China (Provinces Shaanxi, Zhejiang, Yunnan, Fujian, Hainan, Taiwan), Cambodia, Myanmar, Thailand, Vietnam, Japan, India, Indonesia.
