dian stripe without punctures, with anterior edge slightly convex. Submetacoxal line running closely to posterior edge of coxal cavities. Hypopygidium with a truncate posterior edge and with lateral brushes of long and extremely dense hairs (Fig. 23). Protibia almost twice as wide as, meso- and metatibiae about 1.5 times as wide as antenna! club (Fig. 21); meso- and metatibiae with extremely dense, fine and short setae. Pro- and mesofemora about twice, but metafemur almost 3 times as wide as correspondent tibiae. Protarsus slightly narrower, but meso- and metatarsi much narrower than correspondent tibiae, claws narrow and simple. Aedeagus (Figs 24-25) moderately sclerotized. Variability - Length 1.9-2.2 mm. The paratypes show a little variability in coloration of appendages, development of microsculpture of interspaces between punctures and conspicuousness of pubescenece. Diagnosis - This new species is a member of the forcipatus species-group (see EASTON 1957, 1959, KlREJTSHUK & EASTON 1988). It differs from M. (C.) forcipatus KlREJTSHUK et EASTON, 1988 in its larger punctation of dorsal sclerites, characters of secondary sexual dimorphism in metasternum and hypopygidium, somewhat wider male protibia, peculiar aedeagal structure and moderately sclerotized apices of lateral lobes of tegmen. The secondary sexual characters of metasternum and hypopygidium and the aedeagal structure of this species are very different from those of other species of the group with known male. Furthermore, M. (C.)fistuca sp. n. is also distinct: - from M. (C.) astylus EASTON, 1959 in its rounded posterior angles of pronotum, paler appendages, wider protibia with more regular crenellation; - from M. (C.) advertus EASTON, 1957 in its paler appendages and different coloration of pubescence, deeply excised anterior edge of frons, rounded posterior angles of pronotum, wider protibia with more regular crenellation; - from M. (C.) cornutus EASTON, 1959 in its more shining surface, paler appendages, somewhat silvery pubescence and wider protibia; - from M. (C.) livens GROUVELLE, 1908 in its more arcuate pronotal sides with rounded posterior angles, deeply excised anterior edge of the frons, weaker shine and finer punctation of dorsum, more conspicuous and somewhat silvery pubescence; - from M. (C.) lividus EASTON, 1957 in its larger body, more arcuate pronotal sides with rounded posterior angles, broader prosternai process; - from M. (C.) vacca EASTON, 1959 in paler appendages, more arcuate pronotal sides, broader prosternai process and distinctly regular crenel lation of protibia. Etymology - The name of the this new species means "beetle", "rammer", "pile-driver", "pipe".
