Pronotum: saddle-shaped with strongly concave sides (dorsal view) and with outer portions of muscle attachment plates grooved; dorsum pale brown but muscle attachment plates darker brown; lateral lobes pale. Forewings straw-colored, extending beyond the abdomen. Hind wings of examined males had been shed; abdomen pale. Front legs: tibiae with very long, thin bristles arranged into one ventral and two dorsal rows; apical spurs long, sharp, and concave on inner face, middle one longest. Middle legs: tibiae shorter and with fewer bristles than front tibiae. Hind legs: femora with distinct or indistinct oblique brown stripes on middle of outer surface, and with an inner and an outer brown patch proximal to knees; tibiae with a row of bristles along outer edge of posterior margin; spurs 0-1 and i-1 very short, spurs 0-2,0-3; i-2 and i-3 long and sharp and not bearing bristles; third tarsal segment bulbous at distal end.
