Moronopelios Brailovsky, 1988

Moronopelios Brailovsky, 1988: 171–173 (original description).

Redescription. Body elongate ( Figs 2–5 ), relatively narrow, medium-sized, slightly longer than 20 mm.

Head wider than long, nearly quadrate in dorsal view; dorsal surface finely granulate; tylus slightly projecting beyond juga; antenniferous tubercle large, occupying most of anterior head, widely separated, projecting anteriorly of tylus, armed laterally with a spine; antennae relatively long, slender; antennal segment I cylindrical, slightly curved, more than three times as long as head; segments II–III cylindrical, IV fusiform; antennal segment IV longest, III shortest, and I longer than II; preocellar pit deep; ocelli close to eyes, on hypothetical line drawn between posterior borders of eyes; ocellar tubercle protuberant, raised; eyes hemispheric, in lateral view not conspicuously globose, with upper margin in lateral view located slightly above level of frons and vertex; postocular tubercle rounded, forming smooth contour with eye; head in dorsal view with deep longitudinal sulcus extending across frons and vertex; bucculae short, subtriangular, with anterior angle elongate, subacute, not extending beyond middle third of eyes, meeting posteriorly and closed; rostrum reaching middle third of mesosternum; rostral segment I stout, reaching posterior border of head.

Thorax. Pronotum wider than long, conspicuously declivent, densely punctate; collar distinct; anterior and posterior margins smooth; posterolateral margins smooth with anterior third tuberculate; anterolateral margins densely tuberculate and spinose; humeral angles expanded laterally into narrow sharp to obtuse spine; triangular process absent; calli convex, raised above pronotal disk, densely tuberculate; anterior angle exposed, tuberculate to spinose. Scutellum longer than wide; transversely striate; apex subacute. Mesosternum with light, almost obsolete longitudinal mesial depression; metasternum flat, smooth; metathoracic scent gland auricle placed relatively ventrally, bilobed; anterior lobe more developed than posterior lobe; metapleuron lacking lateral process.

Legs. Fore and middle femora ventrally armed with one row of stout spines; hind femur incrassate, curved, dorsally finely tuberculate, and ventrally armed with double row of stout, large, and acute spines; fore femur more than twice as long as head; middle femur reaching posterior border of abdominal sternite IV; hind femur reaching the base of genital capsule; tibiae sulcate; hind tibiae flattened, curved, inner face armed with one row of stout acute spines.

Hemelytra. Macropterous, extending beyond apex of last abdominal segment; clavus and corium densely punctate.

Abdomen. Posterior angle of connexival segments VI–VII with very short spine, sometimes obsolete; abdominal spiracles closer to lateral than to anterior margin.

Male genital capsule. Posteroventral edge with short expansion near midline; lateral angles straight ( Figs 7–8 ). Paramere simple, elongate, apically rounded to subacute ( Figs 9–12 ).
