Diagnosis.

Stoiba clarildae is similar to Stoiba bruneri and Stoiba flavicollis , but it differs from Stoiba bruneri by pale, unicolored antennae, less explanate pronotal margin, shiny, dark brown scutellum, and fully developed hind wing. It differs from Stoiba flavicollis by black elytra without metallic luster, pronotum shape, elytral base much broader than pronotal base, and elytra broadest near basal 1/3.

Description.

Adult (n=1) length 7.7 mm, width 7.6 mm. Body (Figs 17-19) rounded, as long as wide greatly discontinuous between pronotum and elytra in dorsal view; profile distinctly convex, broadest and highest at anterior 1/3 of elytra. Head and pronotum brown; antennae pale brown; scutellum shiny, dark brown; prosternal process black with hypomeron brown; thoracic sterna, coxae, trochanters, proximal 1/3 of femora black; elytra black. Mandible (Fig. 58) with 5 teeth; maxillary palpus (Fig. 60) and labial palpus (Fig. 62) compact. Pronotum (Fig. 17) hemispherical with anterior margin slightly emarginate; lateral edge rounded, slightly angled at middle; pronotal disc slightly convex with surface scale-like, sparsely and finely punctate; explanate margin moderately distinct, shallowly and sparsely punctate. Elytra (Fig. 18) distinctly convex; surface scale-like, finely and moderately punctate, broadest at anterior 1/3; margin area narrower posteriorly, extending to terminal end.
