Key to the Humbertiella  group of Oriental bark mantises

The robust Oriental bark mantises formerly placed among Liturgusidae  form a homogenous group, which may be distinguished from other mantodeans by the following set of characters: body dorso-ventrally flattened, disruptively mottled with grey, green, and dark; eyes strongly exophthalmic; antennae long, surpassing body length in males and half of body length in females; pronotum robust, tuberculate, with narrow lateral expansion rendering its shape more or less ovoid to trapezoidal, antero-lateral corners with an acute lobe; ratio metazona/prozona 1.3– 1.8; margin of pronotum fitting contour of dorsal margin of fore-femora when aligned with pronotum at rest; metathorax with cyclopean ear (DK in males, DNK in females); fore-femora with 4 discoidal and 4 postero-ventral spines emerging from sockets, and with a groove mesad of proximal two postero-ventral spines to accommodate distal-most postero-ventral spine of fore-tibiae; postero-ventral margin of fore-femur slightly mesad of posteroventral spines serrate; genicular lobes with a subapical spine each; fore-tibiae with 7–10 postero-ventral spines of unequal length, the 3rd or 4th being usually longer than neighboring spines, and distal-most spine much longer than penultimate spine; walking leg femora laterally compressed, with dorsal and ventral laminae but without lobes; walking leg tibiae sinuate; hind metatarsi about as long as or slightly shorter than remaining segments combined; wings longer than abdomen in males, mesopterous to macropterous in females; stigma oblique and narrow; cerci long and pilose; male genitalia (where known) with short distal process and more or less simple, tuberculate phalloid apophysis. The genera of this group may be distinguished by the following key:

1. Costal field of male about half as wide as discoidal field; costal field of female strongly curved to sinuate, at least as wide as half of discoidal field.................................................................. Theopompa Stål, 1877 

- Costal field of both sexes much narrower than half of discoidal field, evenly curved.................................2

2. Fore-tibiae with 7–9 postero-ventral spines; pronotum ovoid to trapezoidal, tuberculate, but without large conical processes; females mesopterous............................................................. Humbertiella Saussure, 1869 

- Fore-tibiae with 9–10 postero-ventral spines; pronotum subcircular, with large conical processes; wings of female almost reaching apex of abdomen............................................................. Paratheopompa  n. gen.
