Betalbara robusta (Oberthiir) comb. n. 

 (PI. 3, fig. 319 ; Text-figs. 113-117) 



Drepana robusta Oberthiir, 1916 : 372. 



Drepana robusta Oberthiir, 191 7 : fig. 3642. [Good fig.] 



Drepana robusta Oberthiir, Gaede, 1931 : 27. 



Albara robusta (Oberthiir) Gaede, 1933 : 168. [Fig.] 



The large size, the colour-pattern, the shape of the fore wing, and the elongate 

 signum in the female genitalia separate robusta from the rest of the genus. The 

 affinities of this species are uncertain but it shares sufficient characters with the 

 remaining species to merit provisional inclusion in Betalbara. I prefer to place it 

 here rather than in Pseudalbara gen. n. because of the structure of the male eighth 

 abdominal sternite which, unlike that of Pseudalbara, is not greatly modified. 



The specimens of this species from Shensi in the Museum Koenig, Bonn, are the 

 first known male examples of this species.

PSEUDALBARA Inoue 



(PI. 3, figs. 320, 321 ; Text-figs. 1 18-125) 



Pseudalbara Inoue, 1962 : 7. Type-species Drepana parvula Leech, 1890 : 112, by monotypy. 



As suggested by Inoue (1962), this genus is probably closest to Betalbara, from 

 which it can be separated by the presence of a vestigial frenulum in the male, the 

 colour-pattern of the fore wing, the absence of fasciae on the hind wing, the 

 anastomosis of 5c + R\ with Rs for a short distance distal to cell in hind wing, the 

 strongly modified seventh and eighth abdominal tergites and sternites in the male, 

 and the large corpus bursae in the female genitalia. It can be separated in the male 

 from all species of Betalbara, except manleyi, by the presence of lamellate antennae. 



Two species are known : the type-species parvula (China, S.E. Russia and Japan) 

 and a new species fuscifascia (China).
