First record of the mygalomorph spider family Paratropididae (Arachnida, Araneae) in North America with the description of a new species of Paratropis Simon from Mexico, and with new ultramorphological data for the family.

Bottom Line: The juveniles show ontogenetic variation in the number of cuspules on the labium and endites, and in the number and position of leg trichobothria.This is the second Paratropis species, and the third paratropidid known from both sexes.The scanning electron photographs (SEM) reveal new morphological data and contribute to the knowledge of the family.

ABSTRACT
A new species of the genus Paratropis is described from North America: Paratropis tuxtlensis sp. n., from a tropical rainforest in Veracruz, Mexico. This is the fifth Paratropis and the tenth paratropidid species described and the first North American record of this Neotropical family. The species is described based on adult males and females, and juveniles. The juveniles show ontogenetic variation in the number of cuspules on the labium and endites, and in the number and position of leg trichobothria. This is the second Paratropis species, and the third paratropidid known from both sexes. The scanning electron photographs (SEM) reveal new morphological data and contribute to the knowledge of the family.
