Distribution.

China (Guangdong, Guangxi, Hong Kong, Yunnan); India; Bhutan; Vietnam.

Remarks.

A frequent wasp in Hong Kong, known to visit flowers of Vitex negundo Linn. Nesting biology was reported by Barthélémy (2012). Dover (1926) recorded Pareumenes quadrispinosus Sauss. from the SAR, however, as mentioned in the introduction, none of his examined material survives today, in consequence we are unable to ascertain that he saw P. q. acutus , but because no other subspecies have been collected from Hong Kong since then, there is great probability that it was in fact P. q. acutus . Dissected cells were mass-provisioned with caterpillars in the family Thyrididae (CB pers. obs., det. Dr. Roger Kendrick, Hong Kong).
