形态描述
Male. Colour. Antennae with first segment pitchy, remaining segments brown. Head black. Pronotum black bordered laterad and caudad with yellow. Tegmina and wings brown, darker discoidally. Abdomen and forceps dark brown, Ultimate tergite lighter. Femora pitchy, tibiae tarsi brown.
Head broad, polished, sutures obsolete; eyes prominent. Pronotum parallelsided, rounded caudad, truncate cephalad, all angles rounded; metazona moderately tumid, caudal area depressed. Tegmina a little wider at shoulders than greatest width of head, more than twice as long as pronotum, broadly rounded at shoulders with a short fringe of hairs; texture coriaceous; caudal margin truncate; scutellum very small.
Wings with exposed tips nearly as long as pronotum. Abdomen sculptures with small scattered transverse raised lines; sides of segments six and seven with distinct tubercles. Ultimate tergite with three apical depressins, two lateral and one median; caudal margin sub-truncate mesad; caudal angles rather prominent; sculpture confined to sides and median area. Forceps long and slender, remote at extreme base, approximated beyond base for nearly half their length; inner margins strongly crenulate terminating near a large conical inwardly directed tooth arising from the upper inner margin; beyond median tooth gently curved, enclosing narrowly pear-shaped area; acute apices crossing each other. Penultimate sternite semicircular in outline, convex above, evenly punctate. Length of body (excluding forceps) 10.5mm., length of forceps 5.5mm.
Female: Resembles the male in most respects. Pronotum broader, sides more rounded; ultimate tergite with shallow median depression caudad; sides of abdominal segments without tubercles; forceps simple, long and slender, straight except at extreme apex; penultimate sternite simiar to that of male; length of body (excluding forceps) 11mm., length of forceps 6 mm.
