Duschanov).  Additional material examined.  4 specimens( ZIN): Tajikistan, Khatlon Region, Chiluchorchashma W of Shaartuz,  20.iv.1962(collector unknown).   Notes. Specimensfrom the Amudaryadelta ( Fig. 17A–G, J–L), the coast of the former Aral Seaand NE Karakum( Turkmenistan: Shasenem) differ from those in SW Turkmenistan, having more slender body, less transverse pronotum, more elongate tarsi, lengths of metatarsomeres 1 and 4 are subequal ( Fig. 17D) (metatarsomere 1 distinctly shorter than 4 inpopulations from SW Turkmenistan( Fig. 17I)). Thementioned characters are slightly variable in the population from Uzbekistanand northern Karakum( Turkmenistan: Shasenem). Thepopulation from SW Tajikistanmore similar to those from SW Turkmenistan, but beetles also slightly differ from other two populations. Medvedevin the original description used characters of the north populations for proportions of metatarsi, while the holotypeand specimens from the type locality have other proportions. The status of three disjunctive populations of  M. shasenemacan be established after examination of a larger number of specimens, especially from the area of the middle reaches of Amudarya (in case the species occurs there). We use characters of the north population (from Uzbekistanand NE Turkmenistan) in a key below.   Distribution. Turkmenistan(Karakum desert), Uzbekistan(Karakalpakstan, lower reaches of Amudarya, Aral coast) ( Medvedev & Nepesova 1985b; ZIN collection), Tadjikistan(valley of Kofarnihon, tributary of Amudarya river; new record for the country). 5083092425 1984-05-12 ZIN Meshed-Messerian G.
