Kunchappanai, 17-22.11.93, 1 ♀ leg. D. Boukal & Z. Kejval ( MHNG) .

DESCRIPTION: Length 2.6 mm, width 1.9 mm. Head dark brown. Pronotum and most of elytra blackish-brown, elytra along basal margins and on sutural areas slightly lighter than on disc, each elytron with distinct reddish subapical spot; latter oblique, about as wide as interval to apical margin. Ventral side of thorax laterally about as dark as pronotum and most of elytra, mesoventrite, mesal part metaventrite and abdomen hardly lighter. Femora and tibiae dark reddish-brown. Tarsi and antennae light reddish. Maxillary palpi with palpomere IV tapering, about 2.5 times as long as wide. Length ratio of antennomeres as II 11: III 10: IV 15: V 17: VI 15: VII 17: VIII 12: IX 13: X 12: XI 16; antennomere XI somewhat more than twice as long as wide. Head and pronotum with very fine punctation, punctures not clearly delimited, puncture intervals mostly about twice to three times as large as puncture diameters. Elytral punctation very fine along basal margins, fairly coarse on remaining surface, with punctures fairly well delimited, puncture intervals mostly about as large as to three times as large as puncture diameters. Prohypomera, mesoventrite, lateral parts of metaventrite and of 1st abdominal sternite lacking microsculpture and very finely punctate. Mesal part of metaventrite weakly convex, fairly coarsely punctate on posterior two thirds, very finely punctate near anterior margin. Submesocoxal area almost as long as half of interval to mesocoxa. Metacoxal process truncate, with mesal stria. Mesotibiae and metatibiae moderately curved, mesotibial ventral spur straight. Abdominal sternite 1 with apicolateral transverse impression, middle part of sternite 1 and following sternites with microsculpture consisting of inconspicuous, short striae.

COMMENTS: The species may be easily distinguished by the elytra having each a reddish subapical spot. Nevertheless, we prefer to leave it unnamed until male characters will become known.
