Diagnosis.

Stoiba bruneri (Figs 14-16) is similar to Stoiba clarildae , Stoiba flavicollis and Stoiba indivisa but it is mainly distinguished by the black antennomere XI and more rounded lateral edge of the pronotum. It is also distinguished from Stoiba clarildae by its shiny black scutellum and brachypterous hind wing and from Stoiba indivisa by the distinct posterior half of the elytral margin and brachypterous hind wing.

Description.

Adult (n=7) length 7.0-8.5 mm, width 7.0-8.5 mm. Body (Fig. 14-16) rounded, as long as wide, discontinuous between pronotum and elytra, broadest at anterior 1/3 of elytra in dorsal view; profile moderately convex, highest at middle. Antennae pale with antennomere XI black; antennomere III slightly broader apically, almost as long as IV (Fig. 48). Mandible (Fig. 58) with 5 teeth; maxillary palpus (Fig. 60) and labial palpus (Fig. 62) compact. Pronotum (Fig. 14) brown to dark brown, hemispherical with anterior margin slightly emarginate, laterally rounded, slightly convex with surface smooth; margin area distinct in anterior half, vague in posterior half, shallowly and sparsely punctate. Elytra (Fig. 15) moderately convex, blue to dark blue, finely and moderately punctate, broadest at anterior 1/3; margin area distinctly narrower posteriorly, not extending to terminal end. Spermatheca (Fig. 73) falcate with two openings, receptacle 0.5 times as long as pump.

Distribution.

Cuba: Prov. Guantánamo.
