Six paratypes (3♂, 3♀; INPA, USNM) bear the same locality data as the holotype but with dates from 9 Aug-4 Dec 2006, 2007. One male paratype and all female paratypes were collected in a Malaise trap.

but can be distinguished from these and other congeners of the shannoni group by the distinctively colored male basal flagellomere, which is markedly two-toned with the base whitish yellow and the apical half black. The surstylus is very similar in shape to that of

, but other characters of the male terminalia, such as the relatively well-developed ejaculatory apodeme, the outspread arms of the postgonite in ventral view, and the general shape of the postgonite in lateral view distinguish this species from

|
. Furthermore, colorational characters of the basal flagellomere are very distinctive and constant in the sampling available to us, and based on this evidence, we are currently of the opinion that this is a separate species. Species of the shannoni group, this species and
