Diagnosis. Very similar to P. brunneus in general appearance and in color. Parataenius selvae differs from P. brunneus by its smaller body size, more slender elytra, and pronotal punctation pattern being similar to that in P. simulator and P. estero .

Description. Length 3.5-4.0 mm. Body shiny, yellowish to rusty brown ( Fig. 1 ). Clypeal margin subangulate on each side of deep median emargination, sides slightly arcuate, genae right angled, small with clump of pale setae; clypeal surface over median convexity with coarse transverse rugulae, vertical area with few fine, scattered punctures. Pronotum moderately convex, posterior angles obtusely rounded, basal margin slightly grooved, lateral edge crenulate, fringed with short setae; surface punctures fine and coarse, fine punctures everywhere distributed, separated by more than their own diameter, coarse punctures irregularly scattered along base, lacking on sides of pronotum ( Fig. 7 ). Scutellum pentagonal, smooth. Elytra nearly parallel sided, humeral denticles minute, basal bead very fine; striae narrow, shallowly impressed, strial punctures fine, slightly transversely crenate inner margins of intervals; intervals flat, minute scattered punctures not easily seen. Ventral sclerites smooth; meso-metasternal carina obtuse; metasternum smooth from side to side, disc faintly concave; abdominal sternites with very fine fluting along sutures, sternite 5 grooved; surface of sternites at middle smooth, on sides with longitudinal, irregular punctures bearing short, pale setae; disc of pygidium subgranulate and piliferous, not distinctly eroded. Femora smooth except few setigerous punctures at knee, posterior line of metafemur fine, short; meso- and metatibiae setigerous, moderately dilated apically; mesotibia with trace of transverse ridge; apex of metatibia with row of close setae, without accessory spine, spurs slender, faintly sinuate; basal tarsomere of metatarsus slightly arcuate, one-fourth shorter than upper tibial spur and longer than following three tarsomeres combined, tarsomere 5 linger than combined tarsomeres 3-4. Male terminal spur of protibia hooked inwardly at the tip; male genitalia as in Fig. 16 . Female clypeal rugulae coarser than in male, terminal spur of protibia straight.
