M a l e: Sternite 8 (fig. 29). Sternite 9 acute apicomedially, no fields of ha present. SpP sack-shaped, nearly 1.5x as long as the median lobe, vs about as long as the apical portion of the median lobe. Aedeagus (fig. 54), apical portion of median lobe acutelyangled, slightly longer than the slender parameres, parameres with 2 short setae apically.

Head distinctly narrower than pronotum, eyes large, finely facetted, no distinct temples present, ptfF semicircular, distinct, ampF concave, slightly broader than each of the moderately elevated alpF, no special separation between ampF and clp, alpF with 1 minute puncture. Antennae moderately long, when reflexed extending about to the posterior margin of the pronotum, club 2-segmented, segment 10 slightly longer than broad, segment 11 slightly longer than segment 10.
