mere 3 slightly longer than antennomere 2 and about 1.5 times longer than antennomere 4. Pronotum widest at base, moderately convex, with convex anterior and subtruncate posterior edges, widely rounded anterior and posterior corners, widely arcuate sides, gently sloping to sides, almost as widely explanate as width of scape. Elytra 1 and 1/5 as long as combined width (about twice as long as pronotum), moderately steeply sloping at extremely narrowly explanate sides, slightly suboblique at apex, but at suture nearly truncate, forming a very small suturai corner and without traced suturai lines. Pygidium rounded at apex. Mentum subpcntagonal and narrowed from base, about 3 times as wide as long. Last labial palpomere subcylindrical and more than twice as long as wide. Prosternai process somewhat convex along median part, arcuately widened before subangular posterior edge, widest part of it 1.5 times as wide as antenna! club, extremely narrowly bordered at sides and apex. Distance between mesocoxae about twice and that between metacoxae nearly 4 times as great as that between procoxae. Metasternum subflattened in posterior half and without clear median line. Protibia subtriangular, about 1 and 1/4 as wide as antennái club and moderately crcnulate along outer edge; meso- and metatibiae subtriangular, more than 1.5 times as wide as antenna! club; outer edge of meso- and metatibiae with dense row of moderately long and stout setae. Femora of usual shape, about twice as wide as corresponding tibiae. Protarsus slightly narrower than antennái club, but meso- and metatarsi about a fourth as wide as corresponding tibiae, claws simple. Aedeagus moderately sclerotizcd. Female - Differs from male only in protarsus less than half as wide as antennái club. Ovipositor well sclerotized. Variability - Length 2.3-2.7 mm. One of studied paratypes is dark violet and another - with dark blue pronotum and violet head and elytra. Sometimes pubescence looks rather like whittish than yellowish grey. A small variation is also observed in punctation and sculpture. The level of development of crenellation along outer edge of protibia seems to be rather variable, althought it usually is greater than in most species of the subgenus. Male metasternum sometimes is rather widely depressed in distal 1/2 than subflattened. Diagnosis - This new species is well characterized by comparatively large and robust body very dense dorsal punctation, more or less elongate and very dense punctures on elytra, reduced sculpture on head and pronotum, subtriangular meso—• Figs 88-111.
