Key to Indian species of the subgenus Leluthia (Euhecabolodes)

1. Body distinctly depressed, 2.2–3.6 × longer than its maximum height. Mesoscutum (lateral view) weakly and roundly elevated above pronotum. Neck of prothorax rather long, with a wide and more or less distinctly convex dorsal lobe (lateral view)................................................................................... Subgenus Leluthia s. str.

- Body not or weakly depressed, 1.5–1.8 × longer than maximum height. Mesoscutum (lateral view) distinctly and almost perpendicularly elevated above pronotum. Neck of prothorax short, with narrow and usually weakly convex dorsal lobe (lateral view). (Subgenus Euhecabolodes Tobias, 1962 )............................................................. 2

2. Fifth metasomal tergite not enlarged, only partly finely sculptured anteriorly and not covering following segments. First flagellomere thick, 5.2–5.3 × longer than its apical width. Median length of second metasomal tergite 0.3–0.4 × its anterior width. Body length 2.1–2.5 mm.— India (Karnataka)................................. L. (Eu.) pongamiacola sp. nov.

– Fifth metasomal tergite enlarged, entirely sculptured and almost entirely covering following segments. First flagellomere slender, 6.3–8.0 × longer than its apical width. Median length of second metasomal tergite 0.4–0.6 × basal width. Body length 3.5–3.8 mm .......................................................................................... 3
