A brief generic diagnosis is provided for each genus. Fourteen  out of the currently 23 living crocodilian species have been recorded as being  host to one or more pentastomes. Out of the 32 pentastome species six are  considered species inquirendae. Presently, six genera of crocodilian  pentastomes, Agema, Alofia, Leiperia, Sebekia, Selfia and  Subtriquetra are recognized. African crocodiles harbour eight pentastome  species, six of which have been recorded from the Nile crocodile, Crocodylus  niloticus. Three species belong to the genus Sebekia, Alofia being  represented by two and Leiperia by only one species. Two species,  Alofia parva and Agema silvaepalustris, occur in the dwarf  crocodile, Osteolaemus tetraspis, and the slender-snouted crocodile,  Crocodylus cataphractus, exclusively, but a single Sebekia species  is shared with the Nile crocodile. The genus Agema is endemic to the  African region. Infective stages of the pentastome Sub triquetra rileyi,  thought to utilize Nile crocodiles as final hosts, have been recovered only from  fishes. The largest number of pentastome species is found in the Australasian  region. Of these, the Indo-Pacific croc odile, Crocodylus porosus,  harbours seven, representing the genera Alofia, Sebekia, Lei peria and  Selfia. Selfia is exclusive to the latter host. The genus Subtriquetra has been reported from \"Indian crocodiles\", a term possibly referring to  either Crocodylus palustris, Crocodylus porosus or Gavialis  gangeticus. Ten species of pentastomes parasitizing the crocodilian genera  Alligator, Caiman, Crocodylus and Melanosuchus have been recorded  from the Neotropical region including the southern states of the North American  continent. The two most wide-spread pentastome genera, Alofia and  Sebekia, have been recorded together with representatives of the genus  Sub triquetra and immature and larval forms of Leiperia. To  date the two monospecific genera, Pelonia, from two terrapin species,  Pelusios sinuatus and Pelomedusa subrufa, in South Africa, and  Diesingia from Hydraspis geoffroyana and Hydromedusa  tectifera in South America, are the only chelonian pentastomes recovered  world-wide. A possible exception is the crocodilian pentastome Sebekia  mississippiensis which can reach maturity in exper imentally infected  terrapins.<\/jats:p>","DOI":"10.4102\/ojvr.v73i1.167","type":"journal-article","created":{"date-parts":[[2012,8,27]],"date-time":"2012-08-27T03:22:00Z","timestamp":1346037720000},"source":"Crossref","is-referenced-by-count":19,"title":["A check-list of the pentastomid parasites of crocodilians and freshwater chelonians"],"prefix":"10.4102","volume":"73","author":[{"given":"K.","family":"Junker","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Boomker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2006,9,13]]},"container-title":["Onderstepoort J Vet Res"],"original-title":[],"link":[{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/viewFile\/167\/161","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,1]],"date-time":"2017-06-01T07:21:14Z","timestamp":1496301674000},"score":1,"resource":{"primary":{"URL":"http:\/\/ojvr.org\/index.php\/ojvr\/article\/view\/167"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,9,13]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2006,9,13]]}},"URL":"https:\/\/doi.org\/10.4102\/ojvr.v73i1.167","relation":{},"ISSN":["2219-0635","0030-2465"],"issn-type":[{"value":"2219-0635","type":"electronic"},{"value":"0030-2465","type":"print"}],"subject":[],"published":{"date-parts":[[2006,9,13]]}}}
