Procamallanus (Spirocamallanus) chetumalensis n. sp. (Nematoda: Camallanidae) from the Mayan sea catfish, Ariopsis assimilis, off the Caribbean coast of México.
Procamallanus (Spirocamallanus) chetumalensis n. sp. is described from the stomach and intestine of the Mayan sea catfish Ariopsis assimilis (Günther, 1864), from the Bay of Chetumal, Quintana Roo, México. It is characterized by bifurcate deirids; males have 3 pairs of preanal papillae, 6 pairs of postanal papillae, 2 pairs of transverse elongate adanal papillae surrounding the cloacal aperture, wide caudal alae, spicules of unequal length, and a gubernaculum, and females have a rounded tail bearing a digit-like process terminating in 2 spines. This is the seventh Procamallanus (Spirocamallanus) species reported from fishes in Mexico and the first one recorded in sea catfishes of the Ariidae.
