Rhogogaster gilva ( Konow, 1908)

( Fig. 4v )

Sciopteryx gilva Konow, 1908: 14 , 22–23. Lectotype ♀ hereby designated (ZIRAS, http://dx.doi.org/10.6084/m9.figshare.865631). Type locality: China: дол. р. Джагынгол в Тибетъ (= dol. r. Dzhagyngol v Tibet" 14300); paralectotypes: 1♀ (SDEI, http:// dx.doi.org/10.6084/m9.figshare.1348322), 3♀ ZIRAS, same data as the lectotype (figures of the type series: http:// dx.doi.org/10.6084/m9.figshare.1365431).

Discussion. Konow (1908) described gilva as a variable species. Benson’s treatment (1968) is based on the SDEI specimen from Konow’s collection, which is perhaps not conspecific with the lectotype from the ZIRAS. The shape of the mandibles could not be checked during the present study because of the high risk of destruction of the old type specimens. A (most likely not conspecific) female specimen from Sichuan, which is morphologically very similar to gilva , has a mandible shape similar to that of the male of R. punctulata (i.e., the rectangular tooth is flat and indistinct). The taxon was sometimes treated as a synonym ( Benson 1965) or subspecies ( Kuznetzov-Ugamskij 1929) of Sciapteryx virescens (now in Tenthredo , see below). After the study of the types of both taxa, their synonymy is definitely rejected. Ushinskij (1940) created the subgenus Sciapterina for S. virescens and gilva , but did not select a type species. Therefore, according to Art. 13.3. ICZN (1999) Sciapterina is not available. Hitherto it was wrongly treated as a synonym of Sciapteryx , whereas the two associated taxa belong respectively to Rhogogaster and Tenthredo .
