Distribution.

China (Chongqing, Fujian, Guangxi, Hong Kong, Jiangxi, Shanghai, Sichuan, Zhejiang); Pakistan; India; Nepal; Laos; Vietnam, Mongolia; Korea; Japan.

Remarks.

An abundant wasp in Hong Kong. Dover (1926) first recorded this species from Hong Kong as Odynerus (Rygchium) flavomarginatum Sauss. Its nesting biology was described by Barthélémy (2012) and erroneously identified as Xenorhynchium sp.1. Cells are mass-provisioned with caterpillars belonging to the family Crambidae ( Barthélémy, 2012). There are two colour forms locally (see Figs 52-55 ). In fact this taxon is known for its colour variability and the nominotypical species has no less than 11 recognised subspecies, which is far from being satisfactory, further elucidation of this taxon is needed.
