Open-access A new helminth parasite of fish: Spirocamallanus freitasi sp. n. (Nematoda - Camallanidae)

Abstract

A new species of nematode is described, Spirocamallanus freitasi sp. n. The worms were collected from fishes (Bergiaria westermanni, Pimelodus maculatus and Pimelodus sp.) living in Três Marias Dam (São Francisco River) in the State of Minas Gerais, Brazil. Spirocamallanus freitasi sp. n. differs from Procamallanus iheringi, P. amarali, P. macaensis, P. (Spirocamallanus) pimelodus, P. (S.) solani and P. (S.) pereirai by having digitated larger spicule and from P. cruzi by having not digitated terminal parts of both spicules. It differs also from P. (S.) intermedius by having not larger spicule divided in two undigitated branches and six to nine sclerotized bands in the buccal capsule; P. rarus has three to four sclerotized bands and tridigitated larger branch of longer speicule, differing from S. feitasi sp. n.
