Mikhaljova, Elena V. & Sergeev, Maksim E., 2021, Review of the millipedes of the Sikhote-Alin State Nature Biosphere Reserve (Far East of Russia), with detection of the morphological variability of Diplomaragna terricolor (Attems, 1899) (Diplopoda), Amurian Zoological Journal XIII (2), pp. 167-182 : 169-170

Polyxenus sp.

Polyxenus sp. — Mikhaljova 1993: 34; 2004: 41; 2017: 35; Ganin 1997: 124; 2011: 341; Gromyko, Potikha 2006: 232.

Material. Russia: 6 specimens ( FSCB), Primorsky Krai, Sikhote-Alin State Nature Biosphere Reserve, Yasnaya , Quercus forest, 28.05.1985, leg. M. N. Gromyko.

Remarks. This material still requires a closer determination. At present, only the family Polyxenidae and the genus Polyxenus Latreille, 1802 /1803 are known from the Asian part of Russia: Polyxenus sp. belonging to the Polyxenus shinoharai Ishii, 1983 group was recorded in Lazovsky District, Primorsky Krai (M. Short’s [Deakin University, Australia] personal communication).

Above material is a second find of representatives of Polyxenida taxa in the territories lying between the Ural Mountains in the west and the Pacific Ocean in the east. These specimens most likely belong to the same genus and species group. The reason that we venture to determine these specimens as belonging to Polyxenus is geographical evidence.

Occurrences in the natural landmarks of the Sikhote-Alin State Nature Biosphere Reserve: Yasnaya.
