Description.

-Medium to slender build; size mostly small. Size (in mm): total length males 11.0-16.0, females 12.5-23.0. Integument punctured, finely to coarsely rugulose. Antennae short and incrassate, usually shorter than length of head and pronotum, but more elongate in flaviventris . Fastigium of vertex rounded-pentagonal, moderately (in flaviventris , considerably) longer than broad (Figs 227, 229, 241). Foveolae weak, usually narrow, punctured (Figs 240, 243). Pronotum moderately compressed, medial carina weak, cut by typical sulcus in its middle, with prozona slightly longer than metazona; lateral carinae regularly to irregularly incurved, mostly weak, and often obsolescent between first and second sulcus and partly or wholly in metazona, (in inflexus stronger and more angularly converging on first transverse sulcus (Fig. 244)). Tegminal apices extend slightly beyond hind knees in all subspecies, except bounites , in which they barely reach middle of abdomen. Genital structures show no differences between subspecies. Coloration in shades of brown, stramineous, ivory-white, grey and black, in mottled, striped and occasionally finely speckled patterns, which do not provide striking diagnostic features. In nominate subspecies face is often speckled and/or striped; dorsum is paler and occasionally with a narrow dorso-medial band edged with darker brown pigment. Lateral pronotal lobes are usually dark brownish in upper 2/3, with a contrasting large ivory-white spot in lower third (Figs 236, 239). Hind femur with faint dark bands on upper face; outer face brownish, and lower yellowish; hind knee brown, bordered by a pale ring which matches pale sub-basal ring on tibia. Tibiae otherwise ochraceous, somewhat blackened ventrally.
