1. Granular surface without pubescence; pronotum with lateral margins sinuate; anterior angles briefly, roundly lamellate but never produced as strong lobes; hind margin very slightly concave; scutellum slightly longer than pronotum................................................................................. Neuroctenus Fieber (Figs 9 A–D, 10A–B)
1’. Surface with coarse granules; pronotum with lateral margins more or less dilated forming a narrow anterior lobe; hind margin nearly straight; scutellum much shorter than pronotum......................................................... 2
2. Body beset with long erect hairs, straight or curved. Membrane without veins............... Aphleboderhis Stål (Fig 5 A)
2’. Body without or with few hairs conspicuous. Membrane with veins.............................................. 3
3. Pronotum laterally expanded lobes broad (Fig 4 B), sickle-shaped, sides of pronotum with prominent tooth-like granules in one or two rows; abdomen broadly rounded, connexiva with prominent rounded lateral lobes and granulate margins edges lobe. Hemelytra complete reaching to hind margin of 6th tergite................... Dysodius Lepeletier and Serville (Fig 5 B)
3’. Pronotum slightly or not expanded laterally, sides of pronotum without prominent tooth-like granules in one or two rows; abdomen not rounded and without lateral lobes. Hemelytra complete reaching over of 7 th tergite...................... 4
4. Antennae long, anteniferous tubercles relatively short and usually spine-like not exceed level of outer margins of eyes. Rostral groove distinct, narrow and paralell-sided and terminating at constricted neck region..................................................................................... Mezira Amyot and Serville (Figs 5 D, 6A–E, 7A–D, 8A–D)
4’. Antennae short (Fig 4 C), anteniferous tubercles not short and broadened into plate-like lobes which are rounded and exceed level of outer marging of eyes. Rostral groove distinctly delimited for carinae at the bottom, which are slightly sinuate..... 5
5. The genae exceedingly wide, broadened anteriorly. Scutellum about as long as pronotum on median line.............................................................................................. Lobocara Bergroth (Fig 5 C)
5’. The genae not exeedingly wide. Scutellum much shorter than pronotum on median line with a prominent longitudinal carina..................................................................................................... 6
6. Upper surface of head with clypeus narrowly elevated, with a pair of longitudinal rows of tubercles placed to each other behind clypeus................................................................... Placogenys Usinger and Matsuda
6’. Upper surface of head without clypeus narrowly elevated, with a pair of longitudinal rows of tubercles placed to each other behind clypeus........................................................................................ 7
7. Scutellum shorter than pronotum, the sides sinuate and carinate. Tarsi with short but distinct arolia between the claws. Wings present........................................................ Notapictinus Usinger and Matsuda (Fig 10 B)
7’. Scutellum formed as a triangular area produced backward at middle but completely exposed and narrowed laterally to just behind humeral angles where a small rounded lobe is produced on either side beyond level of humeral angles. Tarsi with claws bearing distinct arolia and a median much longer seta enlarged and curved at tip. Wings absent................................................................................................. Kormilevia Usinger and Matsuda
