Catenotaenia sp. 2

The cestodes from Apodemus peninsulae had 29-34 uterine branches, which corresponds with Catenotaenia afghana Tenora, 1977 , C. californica Dowell, 1953 , C. neotomae Babero & Cattan, 1983 and C. peromysci Smith, 1954 . However, the cestodes found by us have a clearly divided testicular field, a feature which occurs in C. californica but not in the three other species mentioned above. Compared with the present material, C. californica has markedly wider body (0.75-0.83 mm in the present specimens) and smaller scolex (ca. 0.38 mm in the present specimens). Since C. californica , C. neotomae and C. peromysci are Nearctic parasites of heteromyid and sigmodontid (Neotominae) rodents, it is unlikely that they would occur in a murid rodent in Eurasia. The brief original description of C. afghana was based on material from two unrelated host species, Cricetulus migratorius (Pallas) and Alticola sp. from Afghanistan, and it was not stated which was the type host. Moreover, no type specimen was designated ( Tenora 1977). Ganzorig et al. (1999) later redescribed C. afghana from Lasiopodomys brandtii (Radde) from Mongolia but it is probable that the specimens assigned to C. afghana include more than one species. The specimens from Buryatian A. peninsulae may therefore represent another undescribed species of Catenotaenia .
