Abstract

Acanthocephalan fauna are  distributed globally as visceral parasites of vertebrates and arthropods. Morphological description of four known species of the newly described class Polyacanthocephala has been replete with controversies. However,  Mitochondrial  COI  gene  of  two  new  cystacanths  sequences;  Polyacanthorhynchus nigerianus  n.sp.  (NG1 KC904074)  and  Polyacanthorhynchus  echiyensis  n.sp.  (NG5   KC904075)  infecting  some  parentenic  individuals  of Synodontis batensoda in Nigeria were sequenced. The resulting sequences were aligned with 36  other sequences of acanthocephalans  representing   three   widely   recognized   classes;   Archiacanthocephala,  Palaeacanthocephala  and Eoacanthocephala.   The   only   representative   of   the   new   class   Polyacanthocephala   in   the   GenBank/NCBI Polyacanthorhynchus caballeroi (DQ089724) formed a common clade with these two new sequences. This study thus supports existence of the new class Polyacanthocephala as an independent class within Acanthocephala.
