Abstract Anaporrhutine gorgoderids (Digenea Gorgoderidae Anaporrhutinae) found in the body cavity of six species of elasmobranchs from the orders Carcharhiniformes Myliobariformes and Orectolobiformes from Australian waters were found to belong to the genus Staphylorchis Although these specimens were morphologically variable sequences of ITS2 and 28S ribosomal DNA from specimens from three host families and two host orders were identical Based on morphological and molecular data these specimens were identified as the type species of the genus Staphylorchis cymatodes New measurements are provided for S cymatodes and for the first time genetic data are presented for this species In addition to providing new morphological and molecular data for S cymatodes the previously described species S gigas S pans, and S scoliodoii are here synonymised with S cymatodes This implies that S cymatodes as conceived here has remarkably low host-specificity being recorded from eight elasmobranch species from four families and three orders has a wide geographical distribution in the Indo west Pacific from off India in the Bay of Bengal to Moreton Bay in the Coral Sea and is morphologically plastic with body size size of specific organs and body shape differing dramatically between specimens from different host species The genus Staphylorchis now contains only two valid species S cymatodes and S pacifica (C) 2010 Elsevier Ireland Ltd All rights reserved

Anaporrhutine gorgoderids (Digenea: Gorgoderidae: Anaporrhutinae) found in the body cavity of six species of elasmobranchs from the orders Carcharhiniformes, Myliobatiformes and Orectolobiformes from Australian waters were found to belong to the genus Staphylorchis. Although these specimens were morphologically variable, sequences of ITS2 and 28S ribosomal DNA from specimens from three host families and two host orders were identical. Based on morphological and molecular data these specimens were identified as the type-species of the genus, Staphylorchis cymatodes. New measurements are provided for S. cymatodes, and for the first time genetic data are presented for this species. In addition to providing new morphological and molecular data for S. cymatodes, the previously described species S. gigas, S. parisi and S. scoliodonii, are here synonymised with S. cymatodes. This implies that S. cymatodes, as conceived here, has remarkably low host-specificity, being recorded from eight elasmobranch species from four families and three orders, has a wide geographical distribution in the Indo-west Pacific from off India, in the Bay of Bengal, to Moreton Bay in the Coral Sea, and is morphologically plastic, with body size, size of specific organs and body shape differing dramatically between specimens from different host species. The genus Staphylorchis now contains only two valid species, S. cymatodes and S. pacifica.
