Spilogona angulisurstyla (Xue & Xiang, 1998) comb. n.

Helina angulisurstyla Xue & Xiang in Xue and Chao 1998: 1126; Xue et al. 2005: 45; Xue and Wang 2006: 171.

Material studied.

Paratype, ♂: China: Xinjiang, Dong Kunlun, Kaerdong, alt. 4,300m a.s.l., 11.VII.1984, Coll. C.Q. Xiang (IESNU); paratype, ♂: China: Xinjiang, Hejing, alt. 3,000-3,500m a.s.l., 31.VII.1958, Coll. C.Q. Li (IZCAS).

Remarks.

Helina angulisurstyla was described by Xue and Xiang in Xue and Chao (1998) and can be easily distinguished from other Helina species by the slightly shortened arista, pra absent, katepisternal setae 1+1, veins R4+5 and M not diverging distally, abdomen with trapezoid patches, sternite 1 bare, sternite 5 broad and short, cerci long and distal sharped, surstyli not expanded distally but sharp in lateral view. However, these diagnostic characters are practically identical with the generic characters of Spilogona . Our analysis of the paratypes of Helina angulisurstyla revealed a similar external morphology; especially the male genital structures with species in the genus Spilogona . Consequently, we suggest the following new combination: Spilogona angulisurstyla .

Distribution.
