Agrypnus variegatus in Sarkar et al. 2015: 88, nomen nudum

Description:

Male ( Fig. 19 ; Pl. II, Figs. VII and VIII). Body length:

8.77, width: 2.85.

Body ( Fig. 19 ; Pl. II, Fig. VII) brown, marbled with yellow setae, rest of the area with golden setae.

Head ( Fig. 19 ) brown, punctation simple. Frons broader than long, concave. Frontal carina faintly impressed. Vertex weakly concave. Eye pale brown, round, with distinct facets. Labrum brown, raised, broader than long, anterior margin convex. Mandible medially red brown, distally black. Antennae pale brown, extending to the middle of the pronotum. First segment robust, third smallest and fourth onward serrate and subequal in length.

Pronotum ( Fig. 19 ) brown, wider than long, disc convex, medially with a longitudinal shallow groove extending almost up to the anterior margin. Either side of which with a gibbosity on the posterior slope. Punctation ( Fig. 20 ) simple. Submarginal line present. Anterior margin red brown, straight with round anterior angle. Lateral margin crenulate, sinuate before hind angle. Hind angle truncated.

Scutellum ( Fig. 19 ) brown, pentagonal, flat, basally emarginated, convex, setae dense.

Elytra ( Fig. 19 ) 2.01x longer than pronotum, brown, striae punctate, interstriae flat, punctation ( Fig. 21 ) simple, basally emarginate, apically round and weakly spinose along suture.

Prosternum brown,longer than wide, convex, with distinct chin piece, punctation simple. Pronotosternal suture slightly concave, broadly open to middle of prosternum. Hypomeron with depression for accommodating anterior tarsi. Prosternal spine long, emarginated, apically round.

Mesepisternum and mesepimeron do not form part of the margin of the mesocoxal cavity. Metasternum without any groove for receiving mesotarsi.

Metacoxal plate slightly round at middle.

Abdomen brown, punctation double. Setae evenly distributed.

Legs ( Fig. 22 ) brown, claw ( Fig. 23 ) simple, setae present at base.

Genitalia ( Fig. 24 ; Pl. II, Fig. VIII):

Basal piece wide, arms blunt at apex, anterior margin broadly ‘V’ shape, posterior margin weakly concave, lateral margin feebly arcuate, outer margin moderately sclerotised, thin and line like, rest feebly sclerotized; median lobe longer than parameres, arms strongly sclerotised compare to rest, long, arcuate, pointed at base, not exceeding ventral posterior margin of parameres, median lobe gradually narrowing from base to apex, apex rounded, furcae not reaching the anterior margin of parameres; base of outer lateral margin of paramere and inner lateral margin throughout strongly sclerotised, outer lateral margin sinuate, gradually broadening from basal to proximal, proximal to distal nearly straight, apex strongly narrow, rounded, distal teeth small, pointed and more than nine hairs on apex.

Remarks: No Indian congeners examined show any resemblance to the present species.

Etymology: The species name is derived from the body pattern.

Material examined: Holotype: Male: India, West Bengal, Jalpaiguri, BTR, Nimati, Coll. D. Raychaudhuri, 05-vii-

2003.
