Revised diagnosis Distinguished from other species of Voconia by the minute ocelli, occupying 0.12 times length of postocular region; labial segment I swollen subapically on ventral surface; labial segment II swollen ventrobasally and narrowed apically; labial segment III very short (about 0.14 mm long), about 0.2 times length of segment II. Type material Holotype INDONESIA • ♂; E Borneo, Balikpapan, Mentawir River; [1.04° S, 116.75° E]; elev. 50 m; 14 Oct. 1950; A.M.R. Wegner leg.; USI: RMNH.INS 1091587; NBCN (previously RMNH). Redescription Male (Figs 8, 10) BODY LENGTH. ~ 9.1 mm; macropterous. COLORATION. Head: dark brown with a semicircular pale stripe encircling both ocelli; labium lighter than head, brown. Thorax: as head; scutellum dark with brown apical spine. Hemelytron (abducted): clavus dark with distal yellow stripe; corium dark with anteroproximal yellow stripe, posteromedial and distal yellow spots; membrane dark with pale V-shaped marking along R and M veins; membranal veins R and M proximally pale. Legs: dark brown. Abdomen: dark brown; dorsal laterotergites dark brown. INTEGUMENT AND VESTITURE. Head and pronotum: finely granulose with dense, long macrosetae interspersed among dense pubescence; antennifer with short lateral setigerous tubercle; morphologically ventral surface of labium with dense, short macrosetae. Thorax: anterolateral angles of pronotal collar without macrosetae or setigerous tubercles. Legs: posterior row of protuberances on mid and hind femora with four spines on distal half. Abdomen: ventral surface pubescent. STRUCTURE. Head (Fig. 3E): elongate, about 1.5 times as long as wide; anteocular region about half of head length, longer than postocular region (measured to anterior margin of neck); postocular region in dorsal view longer than eye, lateral margins gently rounded; pedicel about 1.1 times length of head width; maxillary plates ellipsoidal, adjacent to and ... |
