groupe bicornis contenant bicornis, cerinthidis, cornuta, tricornis,
groupe emarginata contenant emarginata.
Pas de description des sous-genres ou groupes ici. Selon Michener (nous sommes bien dans ce qu'il appelle Eastern Hemisphere ?) :
etMalar space with minimum length over half basal width of first flagellar segment; middle femur somewhat broadened basal to middle by rounded angle on undersurface; penis valves attaining apices of gonoforceps, which are slender and parallel-sided medially.
etProboscis of ordinary length, usually not reaching beyond middle of thorax in repose; anterior surface of T1 shagreened; antenna usually reaching propodeum and middle flagellar segments usually over twice as long as broad
Voilà qui confirme, mais il reste quand même 5 espèces.T6 and T7 of males are simple, at most with a small median emargination in T7 and rarely in T6; T7 is but little exposed.
