Elytra piceous, each interval bearing two rows of elliptic-ovate, 
white scales and a single row of yellowish brown, setiform scales. 
Scales of underside of thorax and abdomen similar to those of elytra,

brown, covered with a mixture of elongate-ovate and narrow, white 
scales. Tibiae reddish brown, covered with scales similar to those on

gent. Median lobe of male genitalia as in group description (fig. 83).
