Diagnosis.

Stoiba fascicollis (Figs 20-22) is similar to Stoiba marginata but it differs by the black pronotal coloration surrounded by a brown margin, unicolored elytra, pronotal base as broad as elytral base, fully developed hind wing and proximal 1/3 of pro-femur and proximal half of meso- and meta-femur black.

Description.

Adult (n=4) length 8.3-8.7 mm, width 7.5-7.6 mm. Body (Figs 20-22) oval; elytral base as broad as pronotal base in dorsal view; profile moderately convex, highest at anterior 1/3 of elytra. Antenna (Figs 22, 50) brown with antennomeres I and II reddish and polished. Mandible (Fig. 58) with 5 teeth, maxillary palpus (Fig. 60) and labial palpus (Fig. 62) compact. Pronotum (Fig. 20) hemispherical with anterior margin slightly emarginate; dorsal surface slightly convex, more coarsely punctate than elytra with black coloration in middle; margin area brown, shallowly and sparsely punctate. Scutellum shiny black. Elytra (Fig. 21) moderately convex, black with blue luster, finely and coarsely punctate; explanate margin broadest at middle, narrower posteriorly, not extending to terminal end. Hind wing fully developed. Pro-femur brown with proximal 1/3 black; meso- and meta-femur brown with proximal 1/2 black. Spermatheca (Fig. 74) falcate with 2 openings; receptacle 1/3 as long as pump; spermathecal duct long and coarsely coiled.
