Rhyparoclopius Stål, 1868

Redescription. Body broad. Integument with dense, adpressed pubescence and numerous tiny, erect bristles, with glabrous, somewhat shiny areas, which form lines on head, coxae and femora and fusiform or subcircular spots on sternites, laterally. Head: cylindrical or sub-cylindrical, with a discrete transversal sulcus reaching eyes at hind margin; eyes semicircular in dorsal view, with sparse erect bristles; two anterior processes (jugae sensu Giacchi 1987; mandibular plate sensu Weirauch 2008) short and thick; antenniferous tubercles with a small lateral acute protuberance; anteocular portion approximately three times longer than postocular, the latter somewhat wider than the former. Antenna short, inserted toward apex of head; antennal segment I much shorter than the anteocular part of head, enlarged, and mainly toward apex; segment II the longest, lightly curved; segments III and IV very thin, slender. Rostrum: segment I moderately inflated; segment II thinner toward apex; segment III slender, tapering, reaching stridulatory sulcus on anterior portion. Thorax: prothorax divided by a shallow furrow between anterior and posterior lobes of pronotum; anterior lobe with sinuate tomentose ridges and narrow smooth glabrous areas between them; posterior lobe with a pair of submedian carinae, which is divergent toward posterior margin; humeral angles elevated, rounded. Scutellum subtriangular, with a median shallow depression on basal portion. Prosternum larger on anterior portion, with a pair of prosternal spines anteriorly; metasternum larger than mesosternum, which is larger than prosternum. Fore coxae inserted at hind margin of prosternum, contiguous in midline; hind coxae distant from each other; fore trochanters with few spines on ventral face. Fore femora strongly incrassate, fusiform, armed with a row of thick and short spines on midline, ventrally. Fore tibiae curved. Fore tarsi two-segmented, others three-segmented. Hind femora not reaching apex of abdomen. All tibiae without spongy fossa. Membrane of hemelytra glabrous. Abdomen enlarged at about middle portion; connexival margins expanded, considerably wider than hemelytra in macropterous forms; apical angles of connexivum more prominent in distal segments.
