Lyropaeus (s. str.) kejvali , new species

( Figs. 10 , 38 )

Material examined. Holotype. Male ( LMBC), India, Kerala, Cardamom Hills, Pamba env., 77°05'E, 9°25'N, 300 m, 15 May 1999, colls. Z. Kejval & M. Tryzna ; Paratype. Male ( LMBC), same data .

Differential diagnosis. M. kejvali has the smallest body of all Indian species. It resembles L. aurantiacus in the unicolour upper side of the body, but these species differ in the shape of apical processes of paramerae ( Fig. 38 ).

Description. Body small. Head, thorax, elytra, and appendices testaceous, abdomen dark brown. Head small, hypognathous, including eyes slightly narrower than frontal margin of pronotum. Eyes hemispherically prominent, eye diameter 0.59 times frontal interocular distance. Antennae robust, compressed, reaching over middle of elytral length. Pronotum flat, 2.73 times wider than long at midline, widest at basal margin. Posterior margin of pronotum bisinuate. Median longitudinal keel well marked in frontal and posterior parts, interrupted in middle. Scutellum deeply emarginate at apex. Elytra almost parallel-sided, 5.71 times longer than width at humeri; humeri marked by sharp costae 4, epipleura vertical in humeral fourth of elytra, rest of elytra flat, elytra widest at apical third. Elytral costae 1 and 4 strong in basal two thirds, costa 2 weak, costa fourth inconspicuous, absent in most of elytral length. Legs compressed, with dense pubescence. Male genitalia with wide, slightly shortened paramerae and basal processes of phallobase ( Fig. 38 ).

Measurements. BL 6.9 mm, PL 0.68 mm, PW 1.41 mm, HW 2.1 mm, Edist 0.50 mm, Ediam 0.30 mm.

Distribution. India: Kerala.

Etymology. The specific epithet is a patronym in honour of Z. Kejval, the collector of the holotype.
