description: Key to the Indian species of Eumenes Latreille
1. T1 very long (4.5-5.0 mm), lateral margins of postpetiolus substraight and parallel (Figs 25, 29, 77); head much wider than long (Figs 26, 74); temple without hairs.................................................................... 2
- T1 of normal length (3.0-3.5 mm), pyriform (pear-shaped) (Figs 4, 12, 20, 35, 40, 48, 56, 64); head slightly wider than long (Figs 2, 10, 18, 38, 46, 54, 62); temple with hairs............................................................ 5
2. T1, in profile view, distinctly swollen in apical half; antero-lateral angles of pronotum more prominent; scape of male antennae very broad........................................................................... antennatus Bingham
- T1, in profile view, not swollen in apical half (Figs 25, 73); antero-lateral angles of pronotum less prominent; scape of male antennae not very broad, normal.......................................................................... 3
3. Clypeus yellow; scape ventrally yellow; pronotum mostly yellow, black near tegulae; scutellum with yellow marks; ventral side of petiole with two long yellow stripes which occupy the entire apex and merge with apical band on dorsal side; S2 yellow except at base............................................................................ comberi Dover
- Clypeus black; scape entirely black; pronotum mostly black except narrow yellow transverse band on anterior and posterior apex of dorsal face; scutellum without yellow marks; ventral side of petiole without yellow stripes; S2 entirely black...... 4
4. Punctures on T2 at apex, before apical lamella, very thick and dense (Fig. 30); apex of clypeus narrower and more weakly emarginate, with rounded apical teeth (Fig. 26); mesepisternum, tegula, metanotum and propodeum with yellow markings........................................................................................ belli Giordani Soika
- Punctures on T2 at apex, before apical lamella, sparse, integument almost smooth in middle (Fig. 78); apex of clypeus broader and less weakly emarginate, with sharper apical teeth (Fig. 74); mesepisternum, tegula, metanotum and propodeum without yellow markings................................................................. sikkimensis Giordani Soika
5. T2 with long erect hairs, at least at base, about as long as those of T1 (Figs 1, 6, 45, 50).............................. 6
- T2 with hairs very short, much shorter than those of T1 (Figs 9, 14, 18, 31, 37, 53, 61, 71)............................ 7
6. S2 with many whitish hairs, about as long as those of T2 (Figs 1, 6); T2 with long glossy hairs (Fig. 5); punctures on T2 very small and sparse, interspaces much larger than diameter of punctures (Fig. 5)................... affinissimus de Saussure
- S2 with very short hairs, erect long hairs absent (Fig. 45); T2 at base with medium length hairs, rest with much shorter hairs; punctures on T2 larger and denser (Fig. 49)............................................. persimilis Giordani Soika
7. Lateral margin of tegula with a distinct emargination in anterior third (Fig. 55); dorsal surface of pronotum almost flat; meta-
soma extensively ferruginous (Fig. 53).......................................................... placens Nurse - Tegula normal, lateral margin without emargination in anterior third; dorsal surface of pronotum convex as usual; metasoma either little ferruginous or different........................................................................ 8
8. T2, in profile view, strongly gibbous in middle, strongly impressed preapically, its apical margin strongly reflected (Fig. 9); body black with dark red markings (with an orange-yellow spot on interantennal space).......... assamensis Meade-Waldo
- T2, in profile view, not or little swollen in middle, weakly impressed preapically, its apical margin slightly reflected (Figs 18, 31, 37, 61, 71); body colour pattern different................................................................ 9
9. Punctation of T2 fine and dense (Fig. 36); propodeum and T1 extensively ferruginous; clypeus of ♂ more elongate (Fig. 32, 33)...................................................................................... kangrae Dover
- Punctation of T2 coarser and less dense (Figs 21, 41, 66, 72); propodeum and T1 not ferruginous; clypeus of ♂ shorter (Figs 24, 43, 67, 69)....................................................................................... 10
