Pomphorhynchidae and Quadrigyridae (Acanthocephala), including a new genus and species (Pallisentinae), from freshwater fishes, Cobitidae and Cyprinodontidae, in Turkey

Abstract

Production and training institute, antalya, turkey abstract: During a survey of freshwater fishes from Turkey two species of Acanthocephala, one of them new, were found. Pomphorhynchus tereticollis (Pomphorhynchidae) is reported at 24% prevalence in 37 Cobitis bilseli (cobitidae) from lake Beysehir, Konya, for the first time. The eoacanthoacaphalan Triaspiron aphanii gen. n. et sp. n. (Quadrigyridae), at a prevalence of 90%, is described from 29 Aphanius mento (cyprinodontidae), from Kirkgöz springs, antalya. the new genus most closely resembles Raosentis Datta, 1947, both having a small spindle shaped trunk, and Acanthogyrus thapar, 1927, both having a proboscis armature of three circles of hooks. Triaspiron differs from Raosentis in proboscis shape, cylindrical not globular, proboscis armature, three circles, a total of 16 hooks in all, not four circles, a total of 26-30 hooks in all, and trunk spination, two fields of spines in the anterior field with spines arranged in up to 40 circular rows, not a single field with 9-17 rows of spines. Triaspiron differs from Acanthogyrus in having fewer proboscis hooks, 16 compared with 18-24, arranged in three circles, one anterior and two posteriorly placed, with an unarmed region between, not three circles of hooks evenly spaced, and two fields of trunk spines, not one.

The occurrence of Pomphorhynchus laevis (Acanthocephala) in cage-reared rainbow trout (Oncorhynchus mykiss) from Işıklı Spring, Çivril, Turkey

“…In Turkey, some authors have recorded P. laevis in freshwater fishes and also amphibian hosts (Yıldız and Çavuşoğlu 2003). On the other hand, Smales et al, (2012) recorded P. tereticollis in Great Beyşehir Spined Loach Cobitis bilseli Battalgil, 1942 (Cobitidae) from Lake Beysehir, Turkey. Düşen and Oğuz (2008), recovered P. laevis from Marsh frog (Rana ridibunda) in Lake Işıklı.…”

Acanthocephala From Seven Species of Freshwater Fish (Cyprinidae and Cyprinodontidae) From Turkey with the Description of a New Species ofParalongicollum(Pomphorhynchidae)

“…The genera are distinguished primarily by the characteristics of the long neck and the shape of the proboscis (Amin et al, 1991). To our knowledge only species of Pomphorhynchus-Pomphorhynchus laevis (Zoega in Müller, 1776), Pomphorhynchus tereticollis (Rudolphi, 1809), and Pomphorhynchus spindletruncatus Amin, Abdullah, and Mhaisen, 2003-have been reported from Turkey (see for example Akmirza, 2002;Ozturk, 2002;Amin et al, 2003a;Yıldız, 2003;Buhurcu et al, 2007;Heckman et al, 2010;Aydogdu et al, 2011;Smales et al, 2012). Paralongicollum is distinguished from the other 3 genera by having a combination of characters, including a more or less cylindrical trunk not enlarged anteriorly, a cylindrical proboscis that may be enlarged anteriorly, a very long cylindrical neck that is neither twisted nor with a bulbous swelling, and a proboscis receptacle that is not much longer than the neck (Amin et al, 1991).…”

“…Neoechinorhynchus rutili (Müller, 1780) has been widely reported, and Neoechinorhynchus zabensis Amin, Abdullah, and Mhaisen, 2003 has been reported more recently from Turkey (Aydogdu et al, 1997(Aydogdu et al, , 2000Saglam and Sarieyyupoglu, 2002;Amin et al, 2003b;Uzunay and Soylu, 2006;Ozer, 2007;Dörücü et al, 2008;Ozturk and Ozer, 2008;Koyun, 2012;Oguz et al, 2012). A tenth species, Triaspiron aphanii Smales, Aydogdu, and Emre, 2012 (Quadrigyridae), is discussed elsewhere (Smales et al, 2012).…”
