Description.

Body length 7.3-8.6 mm. Coloration: Dorsal surfaces dark brown and sheeny, often with slightly paler margins of pronotum and elytra. Head: Maxillary palps nearly 1.5 × longer than width of head, uniformly brown in color. Thorax: Ground punctation on pronotum and elytra dense and very shallowly impressed. Elytra without rows of serial punctures, each with very faint rows (one dorsal and two or three lateral) of scarce and weakly marked systematic punctures. Prosternum flat to very weakly and broadly convex. Posterior elevation of mesoventrite with posterior face somewhat bisinuate and weak medial longitudinal ridge extending anteriorly (resembling a nose). Abdomen: Apical emargination of fifth ventrite relatively narrow, U-shaped. Aedeagus: (Fig. 26A-C ) Overall shape pear-like, 2.9 × longer than wide; lateral projection on apical region of outer margin of each paramere pointed, ventrally directed; at closest point, dorsal inner margins of parameres separated by distance 0.7 × greatest width of a paramere; dorsal plate of median lobe with neck 0.3 × as broad as base; arms of dorsal plate of median lobe broadening at mid-length, diverging, with apex angulate and dorsally pointed, nearly 0.19 × length of dorsal plate of median lobe; notch between arms at base very narrow; ventral plate of median lobe weakly sclerotized, triangular, apically rounded, apex extending to second 1/3 of dorsal plate; basal piece 0.32 × length of a paramere. In lateral view, aedeagus flattened, with ventral outline of parameres 3.5 × longer than greatest width near base; dorsal outline nearly straight along second 1/3.

Etymology.

Yora, in reference to the Yora peoples of the region where this species is found.

Distribution.

Known from several relatively closely situated localities in southern Peru (Fig. 29B ).

Habitat.

Known specimens were collected at UV lights and at a “stream”.
