Holotype, male (Fig. 94a). Length 3.00 mm. Color of antennae light ferruginous, pronotum black, remainder dark ferruginous. Body in dorsal aspect subrhomboid, with marked constriction between pronotum and elytron; profile with blunt angulation between pronotum and elytron. Rostrum with median and pair of submedian ridges; with sparse suberect scales; epistome with transverse, subangulate ridge. Pronotum with indistinct subapical constriction; disk densely punctate, reticulate; each puncture containing small recumbent seta. Elytra with humeri markedly swollen, laterally subangularly projecting, with coarse punctures; striae distinct, deeply impressed, each with sparse row of suberect scales; intervals costate, weakly microreticulate; sutural intervals with row of smaller punctures, swollen apically; interval 8 apically forming short ridge. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae subbasally dentate. Abdominal ventrites 1–2 forming common cavity, at middle flat, subglabrous, with sparse erect scales; laterally with distinct rim; abdominal ventrite 2 in profile projecting dentiform; abdominal ventrite 5 flat, coarsely punctate, with sparse erect scales. Penis (Fig. 94b) with sides of body subparallel, containing bell-shaped sclerite; apex rounded; transfer apparatus flagelliform, ca. 4 × as long as body; apodemes 3.4 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.26–3.00 mm. Color of body light or dark ferruginous. Female rostrum dorsally medially subglabrous, sublaterally punctate-rugose; epistome simple. Female elytra with humeri less prominent, convex.

This epithet is based on the generic name, which is describing the triangular shape of the elytra very well. It is to be treated as a noun in apposition.
