frontoclypeal suture complete; apex of the labrum
with a reduced, triangular tooth not
overlapping mentum; mentum with a medial
notch; antenna 10-segmented; elytron without
distinct, yellow, longitudinal lines; elytral
apices not capable of completely covering the
pygidium; apex of the elytral suture with an
acute spine; mesothoracic process projecting
apically past the mesocoxa; apical abdominal
spiracle not protuberant; protibia of male
with 1 prominent tooth; mesotarsomere 5 and
metatarsomere 5 without an internal tooth;
parameres with the apex rounded, not expanded.
