Material examined (assigned tentatively)

COLOMBIA (new country record) – Amazonas • 1 ♀; Leticia, indigenous community Monilla Amena ; 4.1866° S, 69.9180° W; alt. 100 m; 11 Nov. 2001; biology students of the Universidad Nacional de Colombia, E. Flórez leg.; ICN-Ao 327 • 1 ♀; same locality as for preceding; alt. 80 m; 3 May 2002; Acuña, Orozco leg.; forest; MPUJ _ ENT 0094605 • 1 ♀; same locality as for preceding; alt. 60 m; 9 Nov. 2002; Botero leg.; manual collection; MPUJ _ ENT 0094591 • 1 ♀; same locality as for preceding; alt. 80 m; 2 Oct. 2003; Mojica, Ortíz, Ospina leg.; várzea forest; manual collection; MPUJ _ ENT 0094590 .

Remarks

The specimens studied here exhibit the paired tubercles of free tergite III directed sub-parallel (nondivergent) and positioned closer to each other. However, due to a lack of knowledge about intraspecific variations and the unavailability of male specimens for studying genital morphology, the material from Colombia is assigned tentatively to this species.

Distribution

Peru: Loreto ( Sørensen 1932; Kury 2003); Colombia: Amazonas.
