Types. Clydostomus cestatus Konow, 1908: 20 . Syntypes , “ Sikkim ”. Lectotype , hereby designated, (MNCN_ Ent 82480, MNCN Cat. Tipos Nº 8128, Fig. 13 , see also http://dx.doi.org/10.6084/m9.figshare.756207). Type locality: India , Sikkim . Paralectotypes : 1 ♂ ( MNCN _ Ent 82481, MNCN Cat. Tipos Nº 8128, http:// dx.doi.org/10.6084/m9.figshare.757297), 1 ♀ ( NHRS ), 1 ♂ (? without abdomen, SDEI ), all labeled “ Sikkim . Discussion. The taxon is the type species of Clydostomus Konow, 1908 . Malaise (1945) synonymized it with Tenthredo , and, based on the tridentate clypeus, within this genus with Fethalia Cameron, 1902 ( type species T. opposita , see also discussion under inguinalis ). But because of its rather different appearance it seems unlikely that cestatus is closely related to the group of T. opposita . In the course of a future reclassification of Tenthredo s.l. , Clydostomus (which is older than Rohwer’s, Malaise’s, and Zhelochovtsev’s genus group names in Tenthredo s.l. ) might be used again. Currently, the species is not placed in a subgenus. See also under Clydostomus merceti .
