Short Communication Description of a new species of the genus Lampropsephus Fleutiaux, 1928 (Coleoptera: Elateridae: Elaterinae: Dicrepidiini) from Konkan, Maharashtra, India

Lampropsephus sulcatus sp. nov. is described from the Konkan region of Maharashtra, India. A note to transfer Propsephus assamensis from Propsephus Candeze, 1859 to Sephilus Candeze, 1878 is included.

So far only one species L. cyaneus Candeze (1878) is before reported from India with a type locality as 'Himalaya'.

Materials and Methods
The specimen was collected from a coastal lateritic outcrop near Bakale Village, Rajapur Taluk, Ratnagiri District in Maharashtra State. The holotype is a female and is deposited in the museum of The Bombay Natural History Society, Mumbai. The identification is based on Candeze (1859Candeze ( , 1878, Schwarz (1905), Fleutiaux (1928Fleutiaux ( , 1935, and Casari (2008). The treatment given by Casari (2008) was the latest and most comprehensive. The morphological terminology was also consulted from Leschen et al. (2010).

Results
Lampropsephus (Fleutiaux, 1928)  The new species can be differentiated from L. cyaneus Candeze, 1878 by having a distinct groove in the posterior half of prothorax which is absent in the latter; prosternal margins distinctly concave in L. cyaneus Candeze, 1878 where as they are subparallel in the new species; prosternal projection stouter than the latter; body multi-coloured in the new species where as it is monochrome cyan in L. cyaneus Candeze, 1878.

Description
Habitus (Image 2) Female: Total length 18.3mm from anterior margin of frontal carina to the tip of the elytra. Maximum breadth 5.57mm at the broadest part of elytra. Integument tricoloured; prothorax including hypomera rufous; head, antennae, proventrite, mesoventrite and metaventrite black; scutellar shield and elytra shining and deep blue. Punctures round, deep and dense. Pubescence yellow ochre.
Head (Image 3): Width (2.86mm) including eyes, slightly more than half of the prothorax width (5.32mm). Anterior margin broadly rounded. Frons broad, squarish, flat, inclined anteriorly, entirely carinate along its width (between eye to eye). Labrum bulging, anterior margin rounded. Mandibles with glabrous tip, bluntly truncate. Antenna (Image 4): Serrate, reaching beyond middle of the prothorax. Antennomere 4-11 with rami. First segment more than the double the length of second. Second and third antennomeres small and subequal. Fourth antennomere the broadest. Antennomere 5-10 distinctly serrate. Eleventh antennomere longer than the preceding, blunt, with broadly rounded apex, lateral sides constricted in the distal half.
Prothorax (length 4.82mm; breadth 5.32mm near the base of the posterior angles) with a distinct shallow grove in the posterior half. Anterior margin darker, slightly rounded in the middle with anterior angles which cover eyes partially. Lateral margin completely carinate from posterior to anterior, narrowing in the anterior half. Posterior angles long with black borders and blunt apex; with distinct, black single carina from the tip to the base of the angle. Posterior margin black, glabrous. Sublateral incision along the posterior margin distinct, broad, squarish. Prescutal notch broad. Hypomeral margin along the pronotosternal sutures angulate.
Scutellum strongly declivous anteriorly with margins as follows: anterior margin carinate and broadly arcuate, lateral margins arcuate and in posterior two third and straight in the anterior third, posterior margin with broadly arcuate apex.
Elytra (length 11.6mm; breadth 5.57mm) with sides parallel tapering posteriorly to broadly rounded apex. Anterior angles indistinct. Striae with distinct and deep punctures which are separated by more than two diameters of punctures. Striae 2,3 and 4 slightly depressed on either side of the scutellum. Interstriae flat.
Prosternum (Image 5) with anterior margin slightly arcuate. Lateral margins slightly tapering J TT posteriorly. Notosternal sutures broad. Mesoventrite declivous anteriorly with an area on either sides of the mesoventral cavity depressed. Mesoventral cavity vertical in the middle with posterior end broadly rounded with thick margins, reaching beyond middle of mesocoxae. Metaventrite (Image 5) truncate between mesocoxae, distinctly separated from the mesosternum by deep suture. Metaventral discrimen distinct, entire. Metasternum slightly projecting between metacoxal plates.
Metacoxal plates (Image 5) broadly rounded along midline of body. Posterior margin sinuate as for the genus with posterior angle distinct and broad.
Legs: Mesocoxal margin formed by mesoventrite, metaventrite, mesepimeron, and mesanepisternum. Mesofemur the broadest. Posteriorly femora with a grove. Tibia long, thin, parallel sided, outer margin with a row of spinose hairs. Distal end of tibia with a row of spiniform hairs and short tibial spurs. Tarsomere 1-3 broad; 4-5 tarsomere thin and glabrous. First tarsomere with band of golden hairs near the apex appearing like Image 7. Sephilus assamensis (Schwarz, 1905). syn. nov. a lamella. Second and third tarsomere lamellate. Claw blade without basal seta arising from the outer surface of the blade.
Abdominal ventrites (Image 6) convex. Pygidium or abdominal process longer than the previous ventrites and with rounded apex.

Etymology
The species is named indicating the groove or sulcus present on prothorax. Masculine.
by Schwarz (1905) the following characters are clearly seen. Antennae reaching beyond the base of prothorax. The terminal antennomere slender, long with pointed apex, as long as the previous two together. Head with complete carina on the frons. Prothorax wider than long, slightly narrowing anteriorly with margins entirely carinate. Notosternal sutures broad and deepened almost entire length. Prosternal process with narrowed apex. Metatarsi distinctly shorter than the metatibia. Based on these characters Propsephus assamensis Schwarz, (1905) can be transferred to Sephilus Candeze, 1878 as Sephilus assamensis (Schwarz) syn. nov.
