New Species of the Genus Mesocoelopus Jacquelin du Val, 1860, and Notes About the Genus Microcoelopus Toskina, 1998 (Coleoptera: Ptinidae: Mesocoelopodinae)

Mesocoelopus fabiani sp. nov. from Turkmenia is described. This beetle is 2.75 mm long, blackbrown, antennae yellow; surface with very small and uniform punctation, eyes separated by 1.3 eye diameters; 5–6th antennal segments transverse, 9–10th segments oblong. Pronotum 1.5 times as wide as long, without gibbosity. Elytra 1.4 times as long as wide, elytral apical margin with about ten smallest teeth. Internal penial sac with 3 spines and 1 papilliform sclerite. M. fabiani differs from Arabian species by the following characters: by absence of gibbosity on pronotum from M. collaris and M. galagheri; by large eyes and homogenous punctation from M. versicolor and M. espagnoli; by shorter pronotum (ratio width: length is 1.5 versus 1.2) and half as number of teeth along elytral ends from M. ingibbosus; by oblong 9 – 10th antennal segments, large eyes, and homogenous punctation of surface from M. buettikeri (8–10th antennal segments are transverse in M. buettikeri). M. fabiani differs from M. niger by exceptionally fine punctation of surface and by large eyes. Besides M. fabiani differs from other species by its aedeagus. M. substriatus Schilsky, 1900 with its bifurcated parameres with outgrowths must be expelled from the genus Mesocoelopus as aedeagus study shows. Microcoelopus Toskina, 1998 differs from the genus Mesocoelopus by the following external characters: body eggshaped, pronotum always ingibbosum, its anterior angles as a rule are acute and reflexed to the lower side of the head. Posterior coxae are separated by the processes of metasternum (posterior coxae not separated in Mesocoelopus); abdominal sternites with single intersegmental sutures and merged (sternites free in Mesocoelopus). Consequently, Microcoelopus is not the synonym of the Mesocoelopus.
