14. Peridinetus illabes Prena, sp. n.

(Fig. 35, 36, 44)

Diagnoses. Peridinetus illabes is one of several species with red anterior, black median and olive posterior portions. Five of them have a large, black, semicircular area on the elytral base and plumose setae in the prosternal channel. Peridinetus illabes is the only species without a patch of white setae on the elytral flank (Fig. 36). Females have the dorsal rostral groove near the basal third (Fig. 44); males have the antenna inserted near the distal fourth (Fig. 36; more basally in all other species).

Description. Total length 3.8–4.8 mm, standard length 3.7–4.7 mm, width 2.1–2.5 mm. Integument black, head, rostrum, tibia and tarsi reddish to dark brown, antenna red; color pattern formed by red, olive green, white and small dark setae, basal half of elytra with conspicuous semicircular black area, anterior half of pronotum red (Fig. 35), elytral flank with semicircular dark area without adjacent white spot (Fig. 36), interstria 5 without white spot in front of ridge. Frons shallowly depressed (male) or convex (female). Rostrum 0.79–0.89 × length of pronotum, antenna inserted in apical third of rostrum (male) or before middle (female); female with dorsal groove at about mid length between antennal insertion and base of rostrum (Fig. 44). Pronotum 0.92–1.00 × longer than wide, sides subparallel in basal half and then curved inward without lateral tumidity or raised setae, front tubulate; disk microreticulate, impunctate. Prosternum with plumose setae. Elytra 1.33–1.39 × longer than wide, humeri 1.44–1.58 × wider than pronotum, subtriangular, sides gradually converging in basal two thirds; striae distinct, interstriae 3 and 5 ridged in distal third, 7 and 9 throughout, preapical callus moderate; tarsal claws subconnate.
