80560408A12F52E390522CA9F91DFB0D.taxon	diagnosis	Diagnosis. Differs from all congeners by the following combination of somatic and gonopodal characters. Head with frontal setae. Collum and each metazona of following body rings with a whorl of long setae at caudal margin. Eyes present. Solenomere with a group of small spines on top. Anterior process of opisthomere subtriangular apically. This species is clearly distinguished in the field from all other millipedes by its characteristic greyish yellow colouration with a yellow stripe dorsally, and its particularly strong odour clearly resembling that of Pachyiulus krivolutskyi from the western Caucasus (= Colchis).	en	Evsyukov, Aleksandr P., Golovatch, Sergei I., Antic, Dragan Z.
