Remarks.

In Vietnam, this species has two color variations of the metasomal segments: one variation is wholly black except for yellow marks at the lateral sides of tergum II, and the other is black with narrow orange bands at the apical margins of terga I and II. Among our material, the latter occurs only in one male, and in this male metasomal sternum II is slightly produced subbasally rather than more or less produced to become tubercules as in other males.
