Sternites 1 to 6 with slightly dense posterior bands of whitish setulae. Distribution. Venezuela, Colombia, Peru *. Type material examined. Holotype, ♀, deposited at the NMW (examined through photographs). Additional material examined. 1 ♀, “ Peru, CA[jamarca], San Ignacio, Tabaconas, 2549 m, 5º11’56.7”S, 79º20’21.1”O, 13–15.x.2017, P. Sánchez ” (UNMSM). Comments. In the specimen examined the frons is a little more divergent than in the type and the thoracic stripes are more evident, and besides that, the setulae of the abdomen of the holotype are denser than in the specimen seen here, which has lost many setulae.
