Genus Perileptus Schaum, 1860

Perileptus Schaum, 1860:663 .

TYPE SPECIES.— Carabus areolatus Creutzer, 1799 .

DIAGNOSIS.— Adults of this genus ( Figs. 5a , 6a ) can be recognized by the following combination of character states: size small to medium (BL = 2.0 to 3.5 mm), fully winged, dorsal surface covered with more or less long pubescence; eyes large, convex, pubescent; frons flat, frontal furrows wide and deep, attenuated posteriorly; terminal palpomeres slender, attenuated apically; mentum free, not fused with submentum; submentum with 10 or 12 setae; antennal scape distinctly pubescent; pronotum narrowed basally, with base broadly projected posteriorly, median longitudinal furrow deeply and sharply defined; elytra elongate and flattened, recurrent stria indistinct; legs short, protibiae without longitudinal furrows.

GEOGRAPHICAL DISTRIBUTION.— Perileptus is a moderately diverse genus with about 50 described species arrayed in four subgenera ( Lorenz 2005). It is represented in the Palearctic, Oriental, Afrotropical, Australian and Neotropical Regions. The study area is within the previously known range of this genus.
