Vollenhovia xingjun

This species produces ergatoid females and is one of the more common species in this genus in Taiwan. (Terayama 2009)

Identification
Terayama (2009) - This species most resembles Vollenhovia benzai, recorded in southern part of Japan by the low subpetiolar process and the densely punctate promesonotal dorsum without a longitudinal smooth band. However, it is separated from the latter by the much larger thin lamellar wall of subpetiolar process.

Some specimens have very weak triangular propodeal teeth.
