title: The first troglomorphic species of the genus Phrynus Lamarck, 1801 (Amblypygi: Phrynidae) from Mexico.
abstract: A new troglomorphic species, Phrynus perrii sp. nov., is described from two adult females from Cueva del Naranjo, Municipio Cintalapa, Chiapas, Mexico. This is the first continental record of a troglomorphic Phrynus species, and the second troglomorphic species of the genus. With the description of this species, in Mexico there are ten extant species, plus one fossil of the genus Phrynus, and it is the seventh species of troglobitic whip spiders from Mexico, making it the country with the highest richness of amblypygids species worldwide.
