A new anoplocephalid cestode from the southern bog lemming Synaptomys cooperi

A new cestode species, Anoplocephaloides bulmeri n. sp. (Cestoda: Anoplocephalidae), is described from the southern bog lemming Synaptomys cooperi (Baird) from Virginia. The general morphology of A. bulmeri strongly suggests that it belongs to the monophyletic Anoplocephaloides Baer 1923 s. str. It differs unequivocally from the other species of Anoplocephaloides s. str. by the distribution of testes in the poral part of the proglottid and also by the number of testes and the maximum length of the cirrus sac and seminal receptacle. Anoplocephaloides bulmeri most closely resembles Anoplocephaloides kontrimavichusi Rausch, 1976, a host-specific parasite of the northern bog lemming, Synaptomys borealis (Richardson).
