Short & Bloom, small stream, SR13-0818-03A (1 ex., SEMC, DNA Voucher SLE1601).

Distribution. This species was originally described from a series of specimens from the summit of Tafelberg Tepui in central Suriname. In 2016, we found one specimen in a small creek at Brownsberg Nature Park in Suriname demonstrating the species was not an endemic to Tafelberg. We were however, tremendously surprised to find series of this species at the Ducke Reserve in Manaus, and in a stream in Rondônia State, Brazil (Fig. 14). The collecting event in Rondônia consisted of hundreds of specimens, and more could have been collected.

Remarks. Despite the more than 1,900 km distance between populations from Suriname and Rondônia, Brazil, the maximum genetic distance in COI is remarkably only 2.1% (Fig. 1).
