( Fig. 24-27)

Leptocometes brevicornis Vlasak, Santos-Silva & Nascimento, 2020: 361 .

Vlasak et al. (2020) described L. brevicornis based on a single male ( Fig. 27) from Ecuador (Pichincha). We have since examined two females ( Fig. 24 -25) and another male ( Fig. 26), all collected in the Ecuadorian province of Pichincha. The male and female from Tambillo have the pronotum mostly with whitish pubescence,and there is a large whitish pubescent macula on the elytra, from centrobasal crest to apex; in the holotype from Quito and the female from Pasochoa, both the pronotum and the elytra do not have large whitish pubescent areas, although there are several small irregular whitish pubescent maculae, especially on the elytra. Notwithstanding, as there are no other morphological differences, we conclude that the two forms are just extreme variations in the pubescence of the same species .

Female ( Fig. 24 -25) differs from male by the shorter antennae, 1.8 times elytral length (about 2.0 times in male); apex of ventrite V truncate (notched in male) with a fringe of black setae (lacking in male); body stouter and femoral club more slender.
