Distribution.

Venezuela (D. Polhemus 1997), Suriname (D. Polhemus 1997), French Guiana (this work), Brazil (D. Polhemus 1997).

Note.

We noticed a fair amount of variation in hind femoral size among the males above. In addition, specimens with larger femora displayed the typical pilose anterior surface of the segment, whereas those with smaller femora showed less developed pilosity. Furthermore, a few of them showed considerably lighter colour than the rest of the series and of the holotype of the species, being yellow/brown instead of brown/black. However, the dense cover of pilose setae on the antennae, sides of the body and over the legs was consistent with the species concept, as well as the spination of the hind trochanter, femur and tibia, and the shape of the paramere.
