Distribution. Described from a cluster of closely situated localities in southeastern Venezuela and western Guyana, we here extend the distribution south to the Amazon River (Fig. 12). We found one specimen on the summit of the Serra do Tepequem, a low Tepui formation in northern Brazil near the border with Venezuela; this locality is very close to its existing distribution. We were surprised, however, when we found specimens on an inselberg in the Sipaliwini Savannah along the southern border of Suriname, and even more surprised when we encountered it near in a rocky stream in the foothills to the Amazon River in Pará State, Brazil.

Remarks. Despite the large range from La Escalera region of Venezuela to the Amazon River, COI sequences for populations from Brazil, Guyana, Venezuela and Suriname are nearly identical (Fig. 1).
