Type material. No. 5546 (sex unknown) Smithsonian Institution Entomology Department; Brodzinsky/Lopez-Penha Collection.

Comparisons. The species was described based on a single specimen. The second specimen, which was found by us, is partially preserved, without the end of abdomen. But the size of the body, wing venation and morphology of antennae correspond to the description of holotype. The small differences are visible: cross-vein m-cu is situated nearer the middle of d-cell basal part than in holotype; the first and the second flagellomeres in examined specimen are joined into fused segment. Additional description. The body ( Figure 2.1 ) is about 3.00 mm long with rostrum very elongated, longer than half the body length, 3.01 mm long and antennae 0.88 mm ( Figures 1.1, 1.4 , 2.2 ). Wing ( Figures 1.3 , 2.1 ) is 3.50 mm long, 0.94 mm wide.
