Perilypus izabal OPITZ nov.sp. (Figs 12, 194, 212, 275)

Holotype: ♂. Type locality: GUATEMALA: IZABAL: Sierra de Merendón, Finca Firmeza, 1181 m, N15°21.869' – W 88°41.374', 29.V-3.VI-2007, Cent. Amer. Broad-leaf forest, Sutton, Monzon & Camposeco (FSCA).

D i a g n o s i s: The genus Perilypus SPINOLA was revised in 1977 (EKIS 1977). This work included a key to species. The available Perilypus izabal specimen keys out to P. ventralis EKIS, from which Perilypus izabal specimens differ by showing a broader aedeagus and visible sternites V and VI are yellow. In P. ventralis specimens sternites IV and V are yellow and the aedeagus is very narrow.

D e s c r i p t i o n: Size: Length 10.0 mm; width 2.8 mm. Form: As in Fig. 212. Color: Cranium black, except clypeus and narrow region behind eyes yellow; antenna black; pronotum yellow at sides, with black triangular discal vitta; prothoracic venter yellow; pterothorax dark brown; elytra black; legs bicolorous, femora mostly flavotestaceous, infuscated and with annulus near apex, tibiae and tarsi black; abdomen bicolorous, visible sternites I-IV dark brown, sternites V-VI yellow.
