1 The tibial spur formula 2/2/2 (fore tibia with two spurs)....................................................... 2 - The tibial spur formula 1/2/2 (fore tibia with only one spur).................................................... 4 2 Lateral pronotal margins carinate; antennomeres III-X spined (male) or sharply angulate (female)...... Spiniphilus gen. nov. - Lateral pronotal carinae absent or only posterior rudiments present; antennae simple................................ 3 3 Male wings with complete venation, medial region with 5 free veins, females with normal elytra and wings.......................................................................................... “ Philus ” globulicollis Thomson - Male wings with simplified venation with only four free veins in medial region ( Fig. 13 ), female micropterous ( Fig. 14 ) and with strongly abbreviated elytra.......................................................... Mantitheus Fairmaire 4 Male wings with simplified venation ( Fig. 15 ), female micropterous ( Fig. 16 ) and with abbreviated elytra (last two abdominal segments not covered); mesonotum without longitudinal median line; antennae shorter, male antennae shorter than body length, antennomere V of male extends to the basal pronotal margin, female antennae never extending to the middle of elytra, antennomere V does not reach basal pronotal margin; the undescribed females ( Figs 16–18 ) are brachypterous and with somewhat shortened elytra...................................................................... Heterophilus Pu - The wings with very complete plesiomorphic venation; mesonotum (with or without stridulatory area) divided by a more or less complete longitudinal median line; antennae longer, male antennae subequal to or longer than body length, antennomere IV of male and V of female extends to the basal pronotal margin, female antennae usually extending to the middle of elytra; females (even if possibly flightless) have normal elytra and wings....................
