Ocular canthus acute; without ventral or dorsal setae. Frons with 2 tumescences. Mentum subquadrate (as long as wide); slightly narrowed at apex; apical margin with long, dense setae. Maxillary apical palpomere 1.5 times longer than the second. Galea of maxilla rectangular (2.5 times longer than wide); with 3 dorsal and 3 ventral teeth. Mandible tridentate (2 apical acute teeth and a lateral lobe acute and directed upwards). Labrum as long as wide; apex evenly rounded with long, dense setae. Antenna with 10 antennomeres, club short (as long as antennomeres 2–7). Pronotum: Apical marginal bead incomplete on middle 1/5. Apex without tubercle, with a small swelling and shallow, narrow fovea. Elytra: Inner surface of apex with transverse tubercles forming approximately 85 parallel lines ( Fig. 8D ). Wings: RA with dense, large, peg-like setae on medial ventral region; without peg-like setae on dorsal surface. Abdomen: Tergite IV with transverse, inconspicuous striae on each side ( Fig. 8A ). Sternite VIII emarginate in both sexes; emargination narrow in female, wider in male. Propygidium without stridulatory area. Venter: Prosternum acute. Propleura with a few, sparse setae on anterior and posterior surfaces, medial surface glabrous. Apex of prosternal process spherical, with dense dorsal setae. Metespisternum with complete carina; inner surface smooth, outer surface evenly rugose; without setae. Metasternum with small, deep, confluent punctures and with long setae, denser on anterior corners. Legs: Male protarsus simple; inner claw simple. Protibia tridentate, basal tooth distant from the others ( Fig. 11B ). Apical margin of mesotibia and metatibia dentate ( Fig. 12B, H ). Female genitalia: Subcoxite 1.8 times wider than long, outer sides narrowed towards apex (basal margin 1.5 times wider than apical margin). Coxite subrounded (as long as wide); surface strongly concave. Subcoxite as wide as coxite; shorter than coxite ( Fig. 13B ). Male genitalia: Parameres approximately 1/2 shorter than phallobase. Parameres with a ventral, truncate tooth on each side; without dorsal teeth. Internal sac without copulatory lamellae or lamellar spiny belt and with 12 accessory lamellae with a flat, oval base (comma-like) ( Fig. 21B ).
