Hylaeogena atroviridis (Fisher, 1922)

Pachyschelus atroviridis Fisher, 1922: 13 .

Hylaeogena atroviridis: Hespenheide 1974: 106 .

Hylaeogena insidiosa Cobos, 1978: 54, syn. nov.

Hylaeogena jakovlevi Obenberger, 1925: 144 (synonymy by Hespenheide 1979: 112). Hylaeogena venezuela Bellamy, 1996: 242, syn. nov. (replacement name for H. bordoni Cobos, 1978: 55). Hylaeogena bordoni Cobos, 1978: 55 (synonymy due to preoccupation by Bellamy, 1996).

In comparing the type of H. jakovlevi from NMPC and type images of H. insidiosa from MNCN, no significant difference was found, hence all examined specimens are considered conspecific.

Examination and comparison of the holotype of H. bordoni Cobos 1978, syn. of H. venezuela Bellamy, 1996 with the types of H. jakovlevi detected no significant differences and conspecificity. In the description of H. bordoni, Cobos (1978) mentioned a reduced number of teeth on the anal ventrite and used this detail inter alia for differentiation, in opinion to diagnose a female. The recent examination however shows that the holotype of H. bordoni is male. The anal ventrite exhibits no teeth. A drawing of the male genitalia is given (Fig 6). Hylaeogena atroviridis is apparently a successful species with a wide distribution range.
