Material examined. 1♁ VENEZUELA, Bolivar state, El Pauji , 4.viii.1990, (1000m asl), R.W. Garrison leg., ABMM .

Known distribution. Southeastern Venezuela.

Diagnosis and remarks. This species possesses a tubercle or apophysis on the ventral BP portion, a feature that is shared only with H. triangulare and H. ictericum . De Marmels (1987) stated that H. pemon keys out to H. ictericum following Williamson’s key (1919), but no further morphological characters are provided to separate the two species. In fact, it is highlighted that “ H. pemon is probably restricted to the “Gran Sabana”, a highland plateau on which the famous “Tepuis” (table mountains) stand” ( De Marmels 1987). DSV and FAAL have seen specimens of both species (not the types), and, apart from coloration characters, they seem to be identical in their morphology. At any rate, we are waiting for examination of the types and a molecular analysis to test the monophyly of these species.
