Currently the family contains 16 genera classified on the basis of the morphology of the rostellar apparatus, rostellar hooks and strobilar anatomy. However, the phylogenetic relationships among the genera are still unknown. In this study, sequences of the near complete 18S (SSU) and 28S (LSU) from rDNA of 13 species of gryporhynchids (adult specimens) representing eight genera (<jats:italic>Cyclustera<\/jats:italic>,<jats:italic>Dendrouterina<\/jats:italic>,<jats:italic>Glossocercus<\/jats:italic>, Gryporhynchidae gen. sp.,<jats:italic>Neovalipora<\/jats:italic>,<jats:italic>Paradilepis<\/jats:italic>,<jats:italic>Parvitaenia<\/jats:italic>,<jats:italic>Valipora<\/jats:italic>) and one species of metacestode from fish (<jats:italic>Neovalipora<\/jats:italic>) were generated. Additionally, sequences of metacestodes of the genera<jats:italic>Amirthalingamia<\/jats:italic>,<jats:italic>Neogryporhynchus<\/jats:italic>,<jats:italic>Paradilepis<\/jats:italic>,<jats:italic>Parvitaenia<\/jats:italic>and<jats:italic>Valipora<\/jats:italic>from Africa recently added to the GenBank database were analysed. Phylogenetic relationships were inferred using maximum-likelihood (ML) and Bayesian inference of each (SSU and LSU) dataset. The phylogenetic analyses indicated that the family Gryporhynchidae is a well-supported monophyletic group within the Cyclophyllidea. The trees inferred with SSU and LSU datasets had similar topologies and suggested that the genera<jats:italic>Glossocercus<\/jats:italic>(two species sequenced) and<jats:italic>Paradilepis<\/jats:italic>(four spp.) are monophyletic. In contrast,<jats:italic>Dendrouterina<\/jats:italic>,<jats:italic>Parvitaenia<\/jats:italic>and<jats:italic>Valipora<\/jats:italic>are paraphyletic, suggesting that the species composition of these genera should be critically reviewed. Interestingly, species of the genera that use the same groups of definitive hosts such as herons (Ardeidae), cormorants (Phalacrocoracidae) and ibis (Threskiornithidae) are together in the phylogenetic tree, even though they differ markedly from each other in some morphological characters, especially shape and size of rostellar hooks.<\/jats:p>","DOI":"10.1017\/s0022149x18000846","type":"journal-article","created":{"date-parts":[[2018,9,20]],"date-time":"2018-09-20T06:38:22Z","timestamp":1537425502000},"page":"763-771","source":"Crossref","is-referenced-by-count":7,"title":["Phylogenetic relationships of the family Gryporhynchidae (Cestoda: Cyclophyllidea) inferred through SSU and LSU rDNA sequences"],"prefix":"10.1017","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0499-6768","authenticated-orcid":false,"given":"M.P.","family":"Ortega-Olivares","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7050-8825","authenticated-orcid":false,"given":"M.","family":"Garc\u00eda-Varela","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2018,9,20]]},"reference":[{"key":"S0022149X18000846_ref16","first-page":"127","volume-title":"Interrelationships of the Platyhelminthes","author":"Mariaux","year":"2001"},{"key":"S0022149X18000846_ref17","first-page":"77","volume-title":"Planetary Biodiversity Inventory (2008\u20132017): Tapeworms from Vertebrates Bowels of the Earth","author":"Mariaux","year":"2017"},{"key":"S0022149X18000846_ref15","doi-asserted-by":"publisher","DOI":"10.2307\/3284540"},{"key":"S0022149X18000846_ref5","volume-title":"Parascript: Parasites and the Language of Evolution","author":"Brooks","year":"1993"},{"key":"S0022149X18000846_ref4","first-page":"651","article-title":"Preliminary phylogenetic systematic analysis of the major lineages of the Eucestoda (Platyhelminthes: Cercomeria)","volume":"104","author":"Brooks","year":"1991","journal-title":"Proceedings of the Biological Society of Washington"},{"key":"S0022149X18000846_ref36","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/25.24.4876"},{"key":"S0022149X18000846_ref9","doi-asserted-by":"publisher","DOI":"10.1023\/A:1006100629059"},{"key":"S0022149X18000846_ref3","first-page":"443","volume-title":"Key to the Cestode Parasites of Vertebrates","author":"Bona","year":"1994"},{"key":"S0022149X18000846_ref6","volume-title":"Planetary Biodiversity Inventory (2008\u20132017): Tapeworms from Vertebrate Bowels of the Earth","author":"Caira","year":"2017"},{"key":"S0022149X18000846_ref13","volume-title":"Parasitic Flatworms: Molecular Biology, Biochemistry, Immunology and Physiology","author":"Littlewood","year":"2006"},{"key":"S0022149X18000846_ref18","doi-asserted-by":"publisher","DOI":"10.1654\/4346.1"},{"key":"S0022149X18000846_ref1","first-page":"91","article-title":"Revisi\u00f3n des cestodes Dilepididae Fuhrm., 1907 des Ardeiformes: note pr\u00e9liminaire","volume":"6","author":"Baer","year":"1960","journal-title":"Bolletino di Istituto del Museo de Zoolog\u00eda"},{"key":"S0022149X18000846_ref7","doi-asserted-by":"publisher","DOI":"10.2307\/3284374"},{"key":"S0022149X18000846_ref8","doi-asserted-by":"publisher","DOI":"10.1023\/A:1006099009495"},{"key":"S0022149X18000846_ref33","first-page":"56","article-title":"[A new subfamily Gryporhynchinae subfam n.
