prosternai process, metasternum and ventrite 1 with very small, rather sparse and distinct punctures and broad interspaces between punctures smoothly alutaceous; other ventrites with somewhat larger punctation and very fine microreticulation. Head slightly and gently convex dorsally, somewhat shorter than distance between eyes, its anterior edge as in Fig. 13. Antennae about 2/3 as long as head width, their club about 1.5 times as long as wide, with rounded apex and comprising about 3/7 of total antennái length. Pronotum with gently sloping and not explanate sides (but widely bordered), its posterior angles widely rounded. Elytra with gently sloping sides and without marked trace of humeral striae; lateral edges scarcely visible from above. Pygidium with broadly rounded apex. Antennái grooves subparallel to slightly divergent. Mentum bisinuate at anterior edge and slightly convex at posterior one, about 3 times as wide as long. Prosternai process moderately wide, about 1.5 times as wide as antennái club and far projecting posteriorly, with a subtruncate and unbordered posterior edge (Fig. 15). Distance between mesocoxae about twice and that between metacoxae about 3.0 times broader than that between procoxae. Mesosternum vaulted medially. Metasternum subflattened, its anterior edge slightly but distinctly emarginate and without any median shining stripe before posterior edge. Submetacoxal line running closely to posterior edge of coxal cavities. Hypopygidium with a transverse posterior edge and with an isolated transverse (quadrangular) shining concavity without punctation and pubescence (its length somewhat less than width of antennái club). Protibia slightly narrower, meso- and metatibiae about 1 and 1/3 times wider than antennái club (Fig. 14); meso- and metatibiae with not very dense, fine and short setae along outer edge. Femora less than 2.0 times as wide as correspondent tibiae, profemur with moderately convex anterior edge. Protarsus slightly narrower, but meso- and metatarsi much narrower than correspondent tibiae, claws narrow and simple. Aedeagus (Figs 16-17) slightly sclerotized. Female - Differs from male in slightly narrower protarsus as well as simple and longer hypopygidium with rounded apex. Ovipositor (Fig. 18) moderately sclerotized. Variability - Length 1.6-1.8 mm. Some paratypes nearly unicolorous, only tarsi paler. General coloration varies from brown to very dark brown. Some variability is observed in punctation and sculpture, particularly in distinctness of transverse striae between punctures on elytra. Length of dorsal hairs varies within 1/2-2/3 of distance between their insertions. Diagnosis - This new species is similar to M.(C.) undosus EASTON, 1964 and M. (C.) impexus sp. n. (see Diagnosis of the latter species). The most expressive external difference from M. (C.) undosus is the finer and sparser punctation of the smaller body, and that from M. (C.) impexus sp. n. are the raised microreticulation between diffuse punctures on dorsum and characteristic apex of male pygidium. This new species has a peculiar configuration of teeth along protibial outer edge and very distinct aedeagal structure. Etymology - The name of this new species means "relative". * Acknowledgements - This work would not have been possible without help of the following persons and scientific organizations who assisted in providing the authors with specimens for study
