Choledocystus vitellinophilum (Dobbin Jr., 1958)

Hosts (prevalence; range): B. raniceps (1/79; 2).

Site of infection: small intestine.

Stage: adult.

Type host and type locality: B. raniceps (= Hyla raniceps), Pernambuco State, Brazil.

Comments: this species was originally described as Glypthelmins vitellinophilum, however, according to Razo- Mendivil et al. (2006) it presents the diagnosis features of Choledocystus . Therefore, we analysed the following characters of C. vitellinophilum in our specimens: the distribution of vitelline follicles which extend from the pharynx level to the end of caeca, position of ovary in relation to acetabulum, relative position of testes, and transversal uterine loops which can overlap the caeca. Until now, this species was known only for the type locality and Argentina (in Lysapsus limellum Cope) (Hamann 2006).
