(Figs. 1, 2 J–R, 3A–D, 4C–F, G, 11–16)
Rhinocylapus Poppius 1909: 2, 5, 43, type species: Rhinocylapus simplicicollis Poppius, 1909 (original designation) Rhinocylapus: Reuter 1910: 155; Bergroth 1920: 73; Hsiao 1944: 380; Carvalho 1952: 48, 1955a:20, 1955b: 221, 1957: 23; Schuh 1995: 36; Gorczyca 2000: 50, Gorczyca 2006
Diagnosis. Recognized by the following combination of characters: body elongate (Figs. 1, 2 J–R); antennal segment bent in males (Figs. 4 C–F); embolium narrow, without punctures, slightly rounded laterally (Figs. 1, 2 J–R, 9A, 16A); ductus seminis with sclerotized portion inside endosoma short. Closely related to Rhinocylapidius, but Rhinocylapus can be distinguished by the shape of the body, structure of the antennal segment II in males, by a narrower embolium without punctures, and by having a sclerotized portion inside the endosoma short.
Redescription. Male. Macropterous, elongate. COLORATION (Fig. 2 J–R). Usually entirely dark castaneous, rarely dark brown or brownish, with yellow stripes or patches. Head. Antennal segment II always strongly darkened, almost black apically, commonly with pale, more or less broadened ring medially. Thorax. Hemelytron. Embolium usually paler than remainder of hemelytron; cuneus with inner angle yellow, sometimes tinged with red or orange, membrane varying from gray to fuscous. Legs. Varying from yellowish to dark brown. Abdomen. Varying from yellowish to entirely dark brown. STRUCTURE AND VESTITURE (Figs. 2 J–R, 3A, 4C–F, 16). Dorsal surface shining, usually covered with relatively dense, short, decumbent to erect, regularly distributed setae, rarely with long, protruding, sparse setae, usually more densely distributed on hemelytron, than on remainder of dorsal surface. Head. Elongated horizontally, conical, commonly covered with short, decumbent, fine setae, rarely with long, protruding setae, usually shining, rarely heavily polished; clypeus protruding; gula matte, sometimes slightly punctate, often covered with few thick, long, and protruding setae; eye relatively small, somewhat removed from pronotal collar; antenniferous tubercle distinctly removed from margin of eye; labrum sometimes with distinct spines; antenna long, usually longer than body length; antennal segment I the thickest, thickened at basal two-thirds, slightly curved, covered with moderately dense, semidecumbent setae; segment II always thickened apically, commonly bent and slightly flattened medially, covered with moderately dense, semidecumbent setae, usually also with minute, short, very dense, erect, apically curved setae on inner surface, apex covered with dense, thick, dark, erect and semidecumbent setae; segments III and IV the longest, slender, covered with moderately dense, semidecumbent, relatively long setae; rostrum long, reaching distinctly beyond half of abdomen; labial segment I long, reaching half of forecoxae; segment IV long, thin, and sharply pointed. Thorax. Pronotum. Pronotal collar distinct, sometimes rugose, rarely covered with erect or decumbent setae; pronotal calli fused, broad, reaching lateral margins of pronotum, usually flat or slightly convex, rarely distinctly raised; pronotal calli always divided by more or less deep longitudinal sulcus, usually impunctate, rarely finely punctate, usually moderately shining, occasionally heavily polished; anterior margin with punctate, transverse incision bordering pronotal collar; anterior angle of pronotum usually gently protruding toward head; posterior lobe deeply and coarsely punctate. Mesoscutum and scutellum. Usually moderately rugose, rarely heavily polished; scutellum usually moderately convex, occasionally distinctly elevated medially. Thoracic pleura. Proepimeron usually impunctate anteriorly, occasionally finely punctate, posterior part of proepimeron deeply and densely punctate; mesepimeron and metepisternum wrinkled, sometimes covered with fine punctation. Hemelytron. Shining, deeply and densely punctate, embolium impunctate, narrow; cuneus small; membrane with major cell triangular, reaching beyond apex of cuneus; minor cell clearly present. Legs. Long, thin; femora and tibiae covered with moderately dense, semidecumbent, rather short setae, rarely femora covered with long, erect setae; trichobothria on meso- and metacoxae very long; claws toothed subapically or without tooth.
Male genitalia (Figs. 11–15). Right paramere: paramere body devoid of setae or with bundle of long, protruding setae; apical process usually blunt; left paramere: paramere body covered with long, protruding, thick setae; endosoma strongly membranous, usually with two lobes, and with long sclerites and sclerotized areas; sclerotized portion of ductus seminis within endosoma short.
Female. Similar to male, but larger, sometimes distinctly larger than male. COLORATION. As in male. STRUCTURE AND VESTITURE (Figs. 3 A, 16). Vestiture same as in male. Structure mostly similar to that in male. Head. Antennal segment I rather cylindrical, thinner than in male, rather straight; segment II thin, cylindrical, not bent; labrum without any spines.
Female genitalia. Not examined.
Distribution. Representatives of the genus are known only from the Oriental Region, most of the species occurring in Peninsular Malaysia and on Sumatra and Borneo.
