Allantus inguinalis Konow, 1908

A valid species, Tenthredo inguinalis (Konow, 1908) .

Types. Allantus inguinalis Konow, 1908: 20–21 . Syntypes ♀, “ Sikkim ”. Lectotype ♀, hereby designated (MNCN_Ent 100194, MNCN Cat. Tipos Nº 8134, Fig. 25, see also http://dx.doi.org/10.6084/m9.figshare.759669). Type locality: India, Sikkim. Paralectotype: ♀, “ Sikkim ” (SDEI, see http://dx.doi.org/10.6084/ m9.figshare.795276).

Discussion. Saini (2007: 116) implied that the paralectotype specimen from the SDEI is the holotype. The species is very similar to T. opposita (F. Smith, 1878) (= Fethalia nigra Cameron, 1902), the type species of Fethalia . Malaise (1945) considered Fethalia to be a subgenus of Tenthredo, but the tridentate clypeus (the only reason for subgeneric separation) seems to be a very weak character. In inguinalis, the clypeus is usually not tridentate. Currently, the species is not placed in a subgenus.
