Diagnosis.

The genus Euodynerus can be distinguished from other genera of Oriental Eumeninae by the following combination of characters: Cephalic foveae in female not in raised area; anterior surface of pronotum without foveae, not densely punctate, pronotum without humeral carina; metanotum angled, without tubercles, not projecting over propodeum; propodeum not raised shelf-like to same level as metanotum, without deep fossae, with superior carinae, with submarginal carina and valvula not produced, without dorsolateral projections; tegula not evenly rounded posteriorly, emarginate adjoining parategula, exceeding parategula posteriorly; axillary fossa in dorsal view not slit-like, as wide as long, oval; TI sessile, in dorsal view about as wide as TII, not carinate, with translucent apical margin.

There are 16 valid species and six subspecies of the genus Euodynerus occurring in the Oriental region in two subgenera: Euodynerus (five species) and Pareuodynerus (11 species, including the new described species in this paper) (Table 1).
