Diagnosis.

Stoiba fuscicornis (Figs 26-28) is one of the two Jamaican species (with Stoiba swartzii ). It is easily distinguished from Stoiba swartzii by leathery brown or reddish brown coloration of pronotum and elytra (not opalescent), and distinguished from Stoiba angusticollis by rounded body shape, finely and coarsely punctate surface, mandible with 4 teeth (Fig. 59), and elongate labial palpus (Fig. 61).

Description.

Adult (n=8) length 6.4−8.0 mm, width 5.6−6.7 mm. Body (Figs 26-28) round; profile moderately convex, highest between anterior 1/3 of elytra and middle. Body color leathery brown to reddish brown (not opalescent); antennae (Figs 28, 52) pale brown to dark brown. Antenna (Fig. 52) reaching elytra, pale brown to dark brown; antennomere II shortest, 0.5 times as long as III or slightly shorter; III 2 times as long as broad, as long as IV or slightly longer; III−VII gradually broader; VII as long as broad; V−XI pubescent. Mandible (Fig. 59) with 4 teeth (rarely with vestigial tooth ventrally). Maxilla (Fig. 61) elongated; palpomere IV setose with fine sensilla structure on apex. Pronotum (Fig. 26) hemispherical with anterior margin slightly emarginate, slightly angled antero-laterally; disc moderately distinct, slightly convex, shiny, smooth or finely punctate; margin area moderately punctate. Scutellum shiny brown, same as pronotum. Elytra (Figs 26-27) finely punctate; explanate margin narrower posteriorly, vague in posterior 1/3.

Distribution.

Jamaica: St. Thomas.
