Description.
Size and form: Body length 1.6-1.8 mm. Body form elongate oval, convex in lateral view (Fig. 4B View Figure 4 ). Color and punctation: Dorsally bicolor, head brown, frons dark brown, clypeus pale brown; pronotum yellow with two small black round spots along posterior margin; elytra dark brown, elytra margins paler (Fig. 4B View Figure 4 ). Ventrally brown; maxillary palps, mouthparts, antennae, and legs yellow. Clypeus and labrum with dense, fine, and weakly impressed ground punctation (punctures separated by 2 × their width); pronotum and elytra ground punctation fine, weakly impressed and sparser than on head (punctures separated by 3 × their width). Head: Clypeus and labrum shallowly emarginate anteromedially, lateral margins of the labrum bearing setae. Thorax: Prosternum carinate medially, strongly raised, acute and pointing anteriorly. Elevation of mesoventrite with two transversal ridges, elevated medially, lateral sides concave; longitudinal ridge broad anteriorly and sharp posteriorly, the point where the three ridges merged wide and blunt (e.g., Fig. 10C, D View Figure 10 ); elevation flat in ventral view; mesoventrite with triangular shape in ventral view. Metaventrite convex in the median region, pubescent with narrow glabrous patch on the medial and posterolateral area; anterior margin extending to mesoventrite elevation. Metafemora with dense hydrofuge pubescence along basal three-quarters of the anterior margin and along basal one-quarter of the posterior margin, then apical half of the posterior margin with sparse setae. Abdomen: Abdominal ventrites very densely pubescent. Aedeagus (Fig. 4B View Figure 4 ) with basal piece 0.7 × the length of a paramere. Base of the parameres narrower than the base of the median lobe; outer margins straight along basal two-thirds, then apically slightly convex, inner margins straight along basal two-thirds and then convex and tapering apically; apex of parameres rounded and pointing inwards. Median lobe shorter than the parameres, approximately triangular, gradually narrowing from the base, broad and rounded apex; gonopore oval-shaped and situated at apex of median lobe.
Etymology.
This species is named after the Patamona, an indigenous tribe located in the mountainous region from which this species is known.
Distribution.
Known from several closely situated localities in western Guyana (Fig. 15 View Figure 15 ).
Life history.
This species was collected at several a variety of stream-associated habitats, including along the margins of detritus and sandy-based streams, as well as in rock seepage habitats adjacent to streams (Fig. 12C View Figure 12 ).
