width, with club, about 1.5 times as long as wide, comprising about 2/7 of total antennái length, antennomeres 3 and 2 subequal in length, and each of them about 2.5 times as long as antennomere 4. Pronotum moderately convex, with truncate anterior and posterior edges, widely rounded anterior and posterior corners, widely arcuate sides, gently sloping to sides, more widely explanalc than 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, separately rounded at apex, forming a suturai corner and with suturai lines traced in distal 1/3. Pygidium widely rounded at apex. Mentum subpentagonal and subparallclsidcd, about 4 times as wide as long. Last labial palpomere subcylindrical and about twice as long as wide. Prosternai process somewhat convex along median part, arcuately widened before rounded posterior edge, widest part of it slightly wider than antennái club, narrowly bordered at sides and at apex. Distance between mesocoxae about twice and that between metacoxae nearly 4 times as great as that between procoxae. Metasternum narrowly and shallowly depressed along the middle in distal half. Protibia subtriangular, about 1 and 1/5 as wide as antennái club and finely crenulate along outer edge; meso- and metatibiae subtrapezoid, about 1.5 times as wide as antennái club; outer edge of meso- and metatibiae with dense row of moderately short and stout setae. Femora of usual shape, about twice as wide as corresponding tibiae. Protarsus about 2/3 as wide as antenna! club, but mesoand metatarsi about a fifth as wide as corresponding tibiae, claws simple. Aedeagus moderately sclerotized. Female - Differs from male only in flattened metasternum. The alone studied female is with missing ovipositor. Variability - Length 1.8-2.1 mm. Appendages are reddish to brownish with antennái club darker. On head of one paratype there is a slightly raised microrcticulation, and punctation of metasternum of another is much sparser than that in the holotype. Elytral apices of one paratype are almost suboblique and form a small suturai corner. A small variation is also observed in coloration and pubescence. Diagnosis - This new species is well characterized by very dense punctation of elytra, rather coarse and dense punctation, and with smooth interspaces on dorsum, rather dark appendages, widely translucent pronotal sides, separately rounded elytral apices and rather long aedeagus with subacute penis trunk. Externally this new species is most similar to M. (C.) cultus sp. n., M. (C.) illustris, M. (C.) profundopunctatus sp. n. and M. (C.) subillustris; although it differs from all of them in extremely dense punctation of head, very sparse punctation of metasternum and structure of male genitalia; and also from the first - in smaller body size, smooth interspaces between punctures on head and pronotum, clearly emarginate anterior edge of head, paler appendages, widely translucent pronotal sides, pronotum widest before very widely rounded posterior corners and trace of suturai lines in distal 1/3 of elytra; from the second - in smooth interspaces between punctures on head and pronotum, widely translucent pronotal sides, clearly emarginate anterior edge of head, larger punctation on dorsum, trace of suturai lines in distal 1/3 of elytra and slightly depressed male metasternum; from the third - in smaller body size, widely translucent pronotal sides, much shorter head, trace of suturai lines in distal
