Synhimantus (Synhimantus) magnipapillatus n. sp. (Nematoda, Acuarioidea) from the Yellow-crowned Night-heron, Nyctanassa violacea cayennensis (Gmelin) (Aves, Ardeidae)

Abstract

Synhimantus (Synhimantus) magnipapillatus n. sp., mainly considering the outstanding size of the cervical papillae and the delicate structure of the cephalic cordons, is not related to any other species of the genus, except for S. (S.) laticeps, concerning the similarities regarding the spicules, that justify their comparison.
