Family SHIRLEYRHYNCHIDAE Campbell & Beveridge, 1994
Introduction
The family Shirleyrhynchidae was erected by Campbell & Beveridge (1994) for two enigmatic Australian genera of cestodes characterised by four bothridia and a typical heteroacanthous tentacular armature. One genus occurs in dasyatid rays and the other in a basking shark. They were initially thought to be related to the Gilquiniidae based on the possession of four bothridia and a typical heteroacanthous armature, but more recent studies (Beveridge et al. 1999) suggest an association with the Eutetrarhynchidae. Their phylogenetic relationships therefore remain to be resolved.
Although initially regarded as endemic, Shirleyrhynchus has recently been shown to occur in Sri Lanka (Beveridge & Campbell 1998) and it is unlikely that Cetorhinicola, the parasite of the basking shark, will prove to be endemic given the pelagic nature of its host.
