Very similar to the previous species, except for the following: anterior quarter of pronotum and posterior quarter of terminal abdominal segment yellowish to pale brown ( Fig. 2 B); lateral portions of the head, entire first abdominal segment and posterior half/entire eight abdominal segment pale; small transverse pale spots might also be present at medioposterior margin of pro-, meso-, and metanotum. Dorsal tubercles slightly elevated. Head more tapering anteriad, widest at posterior 0.2; antennae rather small, approximately reaching anterior margin of labrum. Abdominal segment IX moderately long, ca. 1.9 times as long as wide; basomedian portion slightly tuberculate; apex distinctly emarginated.
