Diagnosis.

Neblinagena can be distinguished from all other laraine genera by its large size (5.5-6.6 mm), slender body form (Fig. 54), dark color, and distinctive pronotum with a lateral longitudinal carina or arcuate-sinuate groove on basal third and two short, converging, prescutellar carinae, each with a deep pit laterally (Figs 57 and 61).

Distribution.

Neblinagena species are endemic to the Guiana Shield region in eastern Venezuela, though presumably they also occur across the borders in Guyana and Brazil (Fig. 5).

Habitat.

Based on the collecting events of specimens examined, Neblinagena spp. seem to prefer small, high elevation streams (>400m elevation), with rocks and forested cover. They have been found in leaf packs and clinging to rocks in the water flow. Their habits are most likely extremely similar to those of Disersus spp. and Hexanchorus spp.
