| abstract | Multisetosa acerbus sp.n. is described from mountains of Southern Daghestan, the Caucasus. The new species is similar to M. persicus Vercammen-Grandjean, Rhode et Mesghali, 1970, but differs in a greater value of most measurements, including Index Pedis, greater number of dorsal, ventral and postposterolateral setae and absence of short basalcilia on sensillae. All type specimens are preserved in the Zoological Institute, Academy of Sciences, St. Petersburg. |
