Arostrilepis horrida (von Linstow, 1901) s.l.

In the present material, Arostrilepis horrida -like cestodes occurred commonly in all Microtus and Myodes species and accidentally in C. barabensis but were absent in A. peninsulae . The data of Zhaltsanova (1992) show an equally wide host spectrum for Arostrilepis horrida -like cestodes in Buryatia. Three species have been described within the A. horrida -complex, i.e. A. horrida from an unknown rodent host, A. beringiensis Kontrimavichus & Smirnova, 1991 from Lemmus sibiricus and A. microtis Gulyaev & Chechulin, 1997 from Microtus spp. (see Kontrimavichus and Smirnova 1991 and Gulyaev and Chechulin 1997). However, applying molecular methods, the BCP has demonstrated a complex of at least 10 species of A. horrida -like cestodes that are poorly differentiated morphologically ( Cook et al. 2005, and K. Galbreath and E. P. Hoberg, unpublished). For example, there may be five Arostrilepis -species in Myodes spp. (species previously assigned to Clethrionomys ) and two species in Microtus spp. in the Holarctic region. The situation is complicated by the fact that it is not known which one (if any) of them is the true A. horrida . Therefore, it is not possible to assign the present specimens to a particular species of Arostrilepis . However, it is probable that the Buryatian material includes at least one undescribed species, i.e. that/those occurring in Myodes spp.
