Helluo rufipes Klug, 1834: 72 .

Description. Color. Dorsal and ventral sides black; labrum and mentum brownish red, legs dark red. Dorsal and ventral body setae black or brownish red.

Head. Labrum transversely not extended; clypeus with 6-9 setae. Mentum round or rectangular; median tooth and base of mentum with 2 setae. 4 th palpomere of labium and maxilla dilated. Last antennomere elongate oval.

Pronotum. Flat, widest in or before middle; not round, punctures more dense on basal area than on lateral area. Lateral margins weakly sinuate to base, base distinctly emarginate laterally.

Scutellum. Densely punctate.

Elytra. Not oval, widest behind middle. Humerus pronounced. Intervals strongly or weakly convex. Apex truncate with a weak emargination.

Genitalia. Male: Apical lamella wide and rounded at apex. Female: Stylomere 1 without setae at apical rim; stylomere 2 with two setae at ventro-lateral margin

Measurements. Male (n=1), TL = 16.0, TW = 5.7, PL = 3.5, PW = 4.5, EL = 9.0. Female (n=2), TL = 15.0 and 16.0, TW = 5.6 and 5.9, PL = 3.4 and 3.6, PW = 4.3 and 4.5, EL = 9.0 and 9.0.

Specimens examined (n=11). Syntypes. INDIA: Eastern India , No. 577, 1 male ( ZMHB) ; SRI LANKA: Coll. Chaudoir, 2 males, 2 females ( MNHN) ; Puwakpitiya Ceylon, Hiver 1906-07, E. Bugnion, 1 male, 1 female ( MNHN) ; Ceylon S., Welioama, Coll. I.B.F., 1 female ( MNHN). SRI LANKA: Sigiriya, Okt, 1977, unknown collector, 1 male ( NHMW). SRI LANKA: Kandy Ceylon , 1905, R. P. Gilles, 2 females ( ISNB) .

Distribution. India and Sri Lanka.

Remarks. Omphra rufipes is most similar to O. complanata , its bright red colored legs, flat pronotum, weakly emarginated elytral apex, elongate oval last antennomere and dilated 4 th palpomeres makes it distinct from O. complanata .
