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).	en	Tran, Tien Van, Vu, Thuong Thi, Nguyen, Cuong Quang, Nguyen, Lien Thi Phuong (2025): Contribution to the knowledge of the potter wasp genus Euodynerus Dalla Torre, 1904 (Hymenoptera, Vespidae, Eumeninae) from Vietnam, with description of a new species and a key to the Oriental fauna.

34ABC53435365449B00EB61CD2768A49.taxon	diagnosis	Diagnosis. The female of this species can be distinguished from other species of Oriental Euodynerus by the following combination of characters: Clypeus as wide as high, apical teeth spaced about 1 / 5 of the maximum width of the clypeus, noticeably reflexed and carinate; pronotal lateral surface concave, with concavity clearly separated from the dorsal surface by a blunt carina; TII with apical margin widely lamellate; SII in lateral view quite strongly convex, without a mediolongitudinal furrow basally; TI – II covered with deep and strong punctures, with interspaces larger than puncture diameter; mesoscutum as long as wide, densely and coarsely covered with flat-bottomed punctures, with interspaces raised to form reticulation.	en	Tran, Tien Van, Vu, Thuong Thi, Nguyen, Cuong Quang, Nguyen, Lien Thi Phuong (2025): Contribution to the knowledge of the potter wasp genus Euodynerus Dalla Torre, 1904 (Hymenoptera, Vespidae, Eumeninae) from Vietnam, with description of a new species and a key to the Oriental fauna.

Scape with sparse small punctures. Pronotum with coarse punctures, spaces between punctures narrow, strongly raised to form reticulation. Mesoscutum densely and coarsely covered with flat-bottomed punctures, with interspaces raised to form reticulation. Mesoscutellum and metanotum with punctures similar to those on mesoscutum. Tegula with sparse minute punctures. Mesepisternum with flat-bottomed punctures, larger and denser posterodorsally, smooth ventrally; mesepisternum with bigger and coarser punctures posterodorsally than on pronotum, barely punctured anteroventrally; epicnemial carina positioned at border between posterodorsal and anteroventral part. Metepisternum with weak short striae laterally and small punctures at upper parts of dorsal area, with sparse shallow punctures in ventral area. Propodeum with punctures on dorsal surface very large, interspaces strongly raised to form reticulation, punctures on lateral parts much smaller and shallower than in dorsal part, posterior surface shiny with strong sparse punctures, with oblique short striae lateral of median furrow. TI – II covered with large and deep punctures, with interspaces as wide as or smaller than puncture diameter, punctures near apical margin of TII deeper and coarser than those on other parts of tergum, punctures on TIII – IV similar to those near apical margin of TII, punctures on TV smaller and weaker than those on TII – IV, TVI with minute punctures; punctures on sternum II deeper and larger than those on TII.
