Notes: Type host for N. golvani was reported as Cichlasoma aureum; however, this species is not distributed in Lago de Catemaco; Vieja fenestrata is currently considered type host for this acanthocephalan species (Salgado-Maldonado et al. 2005 b). Not assigned to either subgenus proposed by Amin (2002) because information on egg shape and membranes is lacking. A recent molecular study suggested that N. golvani represents a complex of cryptic species, which is composed of at least 3 lineages. The first lineage, corresponding with N. golvani sensu stricto, shows a wide distribution, including localities from northeastern Mexico, southwards through central and southeastern Mexico, and further down to Costa Rica. This lineage is associated with cichlid fishes in strictly freshwater environments. Lineages 2 and 3 are distributed in brackish water systems along the Gulf of Mexico and Pacific slopes, respectively; both are associated with eleotrid fishes, and represent 2 cryptic species (Martínez-Aquino et al. 2009).
