Distribution.

China, Thailand, Korea (Chen et al. 2014). Recorded from Thailand by Carmean and Kimsey (1998) and Chen et al. (2014), but no localities given. Chen et al. (2013) recorded 11 provinces in China but not Sichuan.

Comments.

The largely reddish-brown color and lack of a medio-apical process on the second metasomal sternite will help separate this species. We examined only one specimen from Thailand, but the species seems widespread in Asia.
