Description. Female. Body length 11–12 mm (holotype 11.5 mm); fore wing length 10–11 mm (holotype 10.5 mm). Structure as in Eumenes longus sp. nov., but differs as follows. Head in frontal view slightly wider than high (Fig. 7). Distance between inner eye margins (frontal view) at vertex twice more than at clypeus. Clypeus nearly 1.8 × as highas wide (Fig. 7). Metasomal segment 1 in dorsal view gradually widened from base to apex (Fig. 9), tergum and sternum fused, suture between them distinct almost throughout basal part. T 2 in lateral view as long as wide (Fig. 8). Body with slightly less coarse punctures than in E. longus. Color. Black, with following parts yellow: narrow band along inner eye margin extending from bottom to near ocular sinus, spot between antennal sockets, short line at vertex behind eye, short line at basal margin of dorsal pronotum, apical part of parategula and apical margin of T 1. Legs black. Propodeal valvulae dark brown. Wings dark brown, strongly infuscate, veins dark brown. Male. Body length 10–11 mm; fore wing length 9–10 mm. Structure as in female and male of E. longus but clypeus proportionally longer, in frontal view 2.3 × as long as wide, with sharper teeth (Fig. 10). F 11 propotionaly shorter than in E. longus (Fig. 11). Color as in female. Distribution. Northern Vietnam: Tuyen Quang, Ha Giang, Bac Kan, Thai Nguyen, Son La, Vinh Phuc, Ha Noi, Thanh Hoa, Nghe An. Etymology. The specific name refers to the similarity with its congener E. longus. Remarks. This species is similar to E. longus, but can be easily distinguished from the latter by having T 1 gradually widened from base to apex (gradually widened basally and then parallel in E. longus), T 2 in lateral view as long as wide (1.1 × as long as wide in E. longus), and male clypeus with sharper teeth. This species can be distinguished from two Papuan species by having clypeus nearly 1.8 × as high as wide (less than 1.3 × as high as wide in two Papuan species).Published as part of Nguyen, Lien Thi Phuong, 2016, Two new species of the genus Eumenes Latreille, 1802 (Hymenoptera: Vespidae, Eumeninae) from Vietnam, pp. 583-588 in Zootaxa 4093 (4) on pages 585-587, DOI: 10.11646/zootaxa.4093.4.11, http://zenodo.org/record/27097
