Abstract

Examination of ca. 500 rodents [Microtus spp., Myodes spp., Cricetulus barabensis (Pallas), Apodemus peninsulae Th omas] from 14 localities in the Republic of Buryatia (Russian Federation) revealed a minimum of 11 cestode species representing Anoplocephaloides Baer, 1923 s. str. (1 species), Paranoplocephala Luhe, 1910 s.l. (5 species), Catenotaenia Janicki, 1904 (2 species), Arostrilepis Mas-Coma & Tenora, 1997 (at least 2 species) and Rodentolepis Spasskii, 1954 (1 species). At least 5 of these species are previously unknown from the region. Th e taxonomic and phylogenetic position of Buryatian Paranoplocephala species was defi ned by cytochrome oxidase I (COI) sequences (mtDNA). Th e phylogenetic analysis also confi rmed the status of Parandrya Gulyaev & Chechulin, 1996 as a junior synonym of Paranoplocephala s.l. Th e species diversity of anoplocephalid cestodes was signifi cantly lower in Buryatia and North-East Siberia (6-7 species) than in Europe (17 species). Th e connections of the anoplocephalid fauna of Buryatia seem to be closer with Beringia (North-East Siberia and Alaska) than with Europe. Th e present study demonstrated high spatial variation (patchiness) among study sites in cestodes of Buryatian rodents, with the exception of the ubiquitous Arostrilepis horrida (von Linstow, 1901)-complex.

Highlights

The rodent fauna of the Republic of Buryatia (Russian Federation) represents a mixture of Asian, northern Palaearctic and Holarctic species
All A. dentata-like cestodes in the Palaearctic voles have been considered a single species, with the exception of Anoplocephaloides dentatoides Sato, Kamiya, Tenora & Kamiya, 1993 from Myodes rufocanus from Hokkaido, Japan
Based on the cytochrome oxidase I sequences, the A. dentata-like cestodes from Buryatia group strongly, and are conspecific, with the Holarctic species

Summary

Introduction

The rodent fauna of the Republic of Buryatia (Russian Federation) represents a mixture of Asian, northern Palaearctic and Holarctic species. Based on the cytochrome oxidase I (mtDNA) sequences, the A. dentata-like cestodes from Buryatia (hosts Myodes rufocanus and Microtus fortis) group strongly, and are conspecific, with the Holarctic species In addition to Microtus gregalis (Pallas), M. maximowiczii and M. oeconomus, Machul’skii (1958) and Zhaltsanova (1992) reported P. brevis or P. dentata from Myodes rufocanus, M. rutilus, Apodemus peninsulae and Cricetulus barabensis in Buryatia.
