Abstract
Abstract
A new species of Camallanidae was found parasitizing Amazonian fish. The new species of Spirocamallanus Olsen 1952 has a mouth capsule armed with 15-19 spirals, a pre-equatorial vulva, and the presence of a digitiform projection with two small terminal cuticular spines on the tail of the female, while the tail of the male is conical, with the presence of a caudal wing and a tip with two small terminal cuticular spines. Morphologically, the new species shares features with S. pereirai, S. macaensis, S. cruzi and S. halithophus, which are parasites of marine fishes. However, it differs from the new species in spicule morphology, distribution and number of caudal papillae in males, and host environment (freshwater). The new species is added to the fish parasite biodiversity of the Brazilian Amazon.
