Remarks.

Dover (1926) listed Eumens quadratus var. obsoletus from Hong Kong, however, as he recognized himself the justification for this new subspecies lied in the distinct color difference albeit identical structural features between his subspecies and the nominate type species deposited in NHMUK. In our collected material we can recognize at least three color forms of the same species (figs 14-20), these variations are particularly notable on the face, pronotum and T1-T2; the darker form; basis of Dover’s new subspecies, is less common locally than the distinctly marked one. Given the identical structural characters of the various colors forms and the evidence presented by Dover, we propose to synonymise Eumenes quadratus obsoletus Dover, 1926 with E. quadratus quadratus Smith, 1852. It is a common wasp in Hong Kong and has Palearctic affinities. Dissected cells were mass-provisioned with caterpillars in the family Erebidae (CB pers. obs., det. Dr. Roger Kendrick, Hong Kong)
