Rhinocylapus sumatranus: Bergroth 1920: 73; Carvalho 1957: 23; Schuh 1995: 36; Gorczyca 2000: 25, Fig. 5, Gorczyca 2006: 73, Fig. 25

Diagnosis. Recognized by dark castaneous, dorsal coloration with nearly black areas (Fig. 2 N); basal twothirds of antennal segment II pale brown orange; anterior lobe of pronotum somewhat raised medially, incarinate laterally; posterior lobe densely punctate and rugose (Fig. 2 N); endosoma with broad, folded sclerite terminating medially and with thin, membranous sclerite along entire length of endosoma, terminated by cone-like, sharply pointed swelling (Fig. 14 A). The species is most closely related to Rh. kmentii but can be distinguished by its smaller body; slightly paler dorsum; and antennal segment I only somewhat longer than width of head.
Redescription. Female. COLORATION (Fig. 2 N). Body dark castaneous with dark brown, nearly black areas. Head. Dark brown almost black; antenna dark; antennal segment I dark brown blackish; basal one-third of antennal segment II light brown, then orange; antennal segments III and IV missing in the specimen examined. Thorax. Pronotum. Anterior lobe dark brown blackish; posterior lobe slightly paler. Mesoscutum and scutellum. Dark brown blackish; scutellum yellow apically. Thoracic pleura. Dark brown blackish. Hemelytron. Slightly paler than remainder of body; cuneus with inner angle yellowish orange. Legs. Forefemur brown; mesofemur brown, slightly darker than forefemur; remaining segments of each legs missing in the specimen examined. Abdomen. Missing in the specimen examined. STRUCTURE AND VESTITURE (Fig. 2 N). Head. Somewhat shining, almost devoid of setae; frons slightly rugose medially; antennal segment II sparsely covered with setae; slightly thickened apically. Thorax. Pronotum. Covered with very sparse, fine setae; anterior lobe slightly rugose; pronotal calli slightly raised. Mesoscutum and scutellum. Almost devoid of setae; scutellum moderately convex, rugose. Hemelytron. Covered erect, thick, relatively long, dark setae.
Male. Similar to male but slightly smaller. Antennal segment II gently curved medially, inner surface covered with very dense and short, apically curved setae.
Male genitalia (Fig. 14). Endosoma with broad, folded sclerite terminating in the middle of endosoma and with thin, membranous sclerite along entire length of endosoma, terminated by cone-like, sharply pointed swelling.
