摘要

Purpose

Describe a new species of Spauligodon Skrjabin, Schikhobalova, and Lagodovskaja, 1960, parasitizing Thecadactylus rapicauda (Houttuyn, 1782) in Brazilian Amazon.

Methods

A total of 40 host specimens were collected, anesthetized, and necropsied to search for helminths. The adult nematodes were collected, killed, and preserved in 70% ethanol. Specimens of both sexes were examined under a light microscope and a scanning electron microscope.

Results

The diagnosis of the new species was based on a set of characteristics: the number of caudal spines in both males and females, absence of a spicule, number and arrangement of cloacal papillae in males, egg shape, and vulva position in females. We provide an identification key to the species from the Neotropical and Panamanian realms. We also analyzed the egg morphology in the species description of Spauligodon and proposed a classification for egg morphology and shape.

Conclusions

Spauligodon caxiuana n. sp. is the 56th species of the genus, the fourth for the Neotropical realm, the third species record of Spauligodon spp. in Brazil, and the first in the Brazilian Amazon.
