Diagnosis. Females are easily separated from all the oth- er genera of subfamily Pepsinae by the following combination of characteristics. Hind tibia with a smooth full length furrow along upper margin of brush ( Fig. 1A) and covered with short spines somewhat regularly set, some basomedian spines attaching on small scale-like teeth; transverse furrow on S2 weak, often obsolete in its middle; antennae long, F1 5.0-6.3 times as long as broad at apex; claws with a submesal perpendicular additional small tooth; vein 1cu-a of forewing located distally of Media, apart ca. half-length of Media ( Fig. 1B); body markings much various, largely black to extensively yellow to brown, but face along inner orbit always with yellow or creamy white stripe.

Males are easily separated from all the other genera of subfamily Pepsinae by having apical margin of S6 with a row of dense short bristles equal in length ( Figs. 1C, 2E, 3E ) and antennae serrate, each segment of F2-11 strongly convex beneath ( Figs. 1F, 2C, 3D ). F1 2.3-4.2 times as long as broad; vein 1cu-a of forewing as in female; hind tibia with a smooth furrow as in female (but scale-like tooth absent); tarsal claws usually without additional tooth, but sometimes bifid, with additional inner small tooth; body black to extensively yellow and brown as in females.
