Head almost square, parallel-sided, with bilobate

antennomeres black with light luster (holotype)
or first antennomere with strong golden luster
and second antennomere black (paratype). First
two basal antennomeres with pubescence, third
antennomere brown basally, fourth antennomere
testaceous basally, with very fine white
pubescence; remaining antennomeres testaceous
and tomentose. Pronotum convex, black, shiny,
with sparse coarse punctuation and with fine
transverse microsculpture. Dorsal disc of
pronotum in frontal part with short fine
longitudinal stripe of yellow scales, lateral parts
with large circle-shaped spot of yellow scales.
Disc of pronotum in centrum of basal part without

from other species of the genus Doliops Waterh.
by shape of surface.
