Cystacanths of Oncicola venezuelensis (Acanthocephala: Oligacanthorhynchidae) in Caribbean termites and various paratenic hosts in the US Virgin Islands

Cystacanths of Oncicola venezuelensis (Acanthocephala: Oligacanthorhynchidae) were discovered in the hemocoel of Caribbean termites (Nasutitermes acajutlae) on St. Thomas and St. John islands ill the U.S. Virgin Islands. In addition to Occurring in the insect intermediate host. cystacanths were present in subcutaneous nodules of lizards (,Anolis cristaellus and Anolis stratulus). in the greater omentum of small Indian mongooses (Herpestes auropunctatus). and embedded in mesenteries of pearly-eyed thrashers (Margarops fuscatus). These vertebrates likely are paratenic hosts. although a definitive host in the Virgin Islands is yet to be discovered. Cystacanths from intermediate and paratenic hosts agree fully with the original description of proboscis armature. including size and shape of hooks and their roots. of the species. Qualitative features of developing and rowing Structures agree with the original description of the species, but the sizes Lire smaller.
