Sulawesifulvius gen. nov.

Type species: Sulawesifulvius schuhi , new species

Diagnosis

This genus is not similar to any known genus of Cylapinae . It has a superficial similarity to the genus Peritropis Uhler (Fulvinii) , but differs from it by the structure of the antennae, hemelytra, and parameres.

Etymology

Named according to Sulawesi (where is the type locality) and the type genus of the tribe Fulviini , in which the new genus is placed. Gender masculine.

Description

Body small, elongated, oval, flattened dorsoventrally, covered with very short, scalelike setae. Head relatively short, vertex and frons with two raised tubercles; clypeus very distinct. Antennal tubercles small, almost contiguous with margin of eye. First and second antennal segments relatively thick, second slightly narrowed in the middle, covered with short setae. Third segment longest, very thin, with sparse, fine, obscure setae; fourth segment short, thicker than third, covered with long setae. Rostrum straight, thin, and short, reaching beyond forefemora; first rostral segment shorter than head, remaining segments subequal.

Pronotum short, broad, lateral margins elevated, anterior angles of pronotum protruding, enveloping head and reaching beyond middle of eyes ( Fig. 1 ). Single, erect, scale­like seta on top of angles of pronotum. Antero­lateral part of pronotum distinctly separated. Calli raised with depression between them. Posterior margin of pronotum almost straight. Mesoscutum well exposed, raised, with small, oblique carina on sides. Scutellum with small, raised subapical tubercle mesially.

Hemelytra well developed, distinctly tapering towards membrane. Exocorium very broad, slightly elevated. Clavus slightly raised, costal fracture short. Cuneus very long, enveloping membrane ( Fig. 1 ); membrane narrow, elongated, two­celled, the minor cell very small; its venation thin.

Ostiolar peritreme very small. Fore­ and middle legs cursorial, hind legs probably saltatorial. Mesofemora with at least five trichobothria in distal half ( Fig. 5 ). Metafemora distinctly enlarged, with distinct subapical depressions on sides, covered with dense, scalelike setae and bearing eight long trichobothria apically. Metatibiae with scale­like setae, partially covered with very long, fine, protruding setae. Longitudinal rows of short spines along each tibiae and few long, thick spines on apical portion of metatibiae ( Fig. 3 ). Tarsi two­segmented, fore­ and mesotarsi short, metatarsi slightly longer, first segment with row of thick, short spines ( Fig. 4 ), second slightly swollen distally; parempodia setiform; claws with distinct, subapical tooth ( Fig. 4 ).

Parameres asymmetrical, large, with long, sharp processes ( Figs 6–9 ), aedeagus membranous, relatively small (Fig. 10).
