Choanotaenia atopa (Cestoda: Dilepididae) is described (host: domestic cat from the vicinity of Manhattan, Kansas); its natural host is pres umed to be a rodent. Choanotaenia atopa is morphologically similar to cestodes of 6 species, all from rodents, formerly placed in the genus Rodentotaenia Matevosian, 1953, and subsequently removed to the genera Choanotaenia Railliet, 1896, or Monopylidium Fuhrmann, 1899. The syst ematic position of those cestodes is discussed; Monopylidium and Roden totaenia are treated as synonyms of Choanotaenia. Choanotaenia atopa i s distinguished by size and form of rostellar hooks, regularly alterna ting genital pores, and other characters in genital organs.
