Further study on Procamallanus (Spirocamallanus) pintoi (Kohn et Fernandes, 1988) (Nematoda: Camallanidae) in Corydoras paleatus and Corydoras micracanthus (Siluriformes: Callichthyidae) from Salta, Argentina, with a key to congeneric species from Neotropical Realm

This study describes the morphology of Procamallanus (Spirocamallanus) pintoi (Kohn et Fernandes, 1988), isolated from the intestine of Corydoras micracanthus Regan, 1912 and C. paleatus (Jenyns, 1842) (both Callichthyidae, Siluriformes) from Bermejo and Juramento River basins, respectively, province of Salta, Argentina. This is the first record of P. (S.) pintoi in C. micracanthus from Northwestern Argentina. The light and scanning electron microscopy observations of P. (S.) pintoi, revealed a few previously unreported morphological details of the cephalic region, vulva and caudal region of males. In addition, morphometric variability was observed in, mainly body size, glandular oesophagus length and position of the vulva between present specimens and those described in previous studies. A key to the species of Procamallanus (Spirocamallanus) from the Neotropical Realm is proposed.
