Distribution.

China (Guangdong, Hong Kong); India; Bhutan; Myanmar; Thailand; Vietnam.

Remarks.

A frequent wasp in Hong Kong. Barthélémy (2012) reported on the nesting biology of this species under the name of Zethus sp.1. Cells are mass-provisioned with caterpillars belonging to the family Geometridae and Noctuidae ( Barthélémy, 2012). It is expected that Zethus malayanus Gusenleitner, 2010 distributed from Malaysia to Guangdong will also be recorded in Hong Kong.
