We describe a new nematode species, Baylisascaris potosis n. sp., isolated from captive kinkajou, Potos flavus, from the Cooperative Republic of Guyana. The nematode was found in fecal specimens, identified morphologically, and confirmed genetically. The new species is similar to Baylisascaris procyonis, Baylisascaris columnaris, and other Baylisascaris species, but is distinguished by the position of the male phasmidial pole. Nuclear and mitochondrial DNA sequence analyses confirmed that the new species is phylogenetically distinct from all the members of the genus Baylisascaris, and groups with B. procyonis and B. columnaris. This nematode is the 10th species assigned to the genus Baylisascaris.
