Distribution.

China (Fujian, Guangdong, Guangzhou, Guangxi, Henan, Hong Kong, Jiangxi, Macao, Sichuan, Shanghai, Taiwan,Yunnan); Vietnam; Philippines.

Remarks.

Displays elaborate nesting biology, particularly progressive provisioning. Construct cell partitions and entrance collar with resinous material (likely as an ant repellent). Recorded by Barthélémy (2012) as Allorhynchium sp.1. Cells are progressively-provisioned with caterpillars belonging to the family Tortricidae ( Barthélémy, 2012). An abundant wasp in Hong Kong.
