A new species of Trachelas L. Koch, 1872 belonging to the tranquillus species group (Araneae: Trachelidae) from southern Mexico

The family Trachelidae comprises 29 genera and 300 species recognized worldwide (World Spider Catalog 2025). In North America, two genera have been recorded: Meriola Banks, 1895, and Trachelas L. Koch, 1872. Trachelas is the most diverse genus within Trachelidae, with 93 species documented globally. It has been suggested that the New World representatives of this genus are not congeneric with the type species or other Old World members due to substantial somatic and genitalic differences (see Platnick & Shadab 1974a: 3 for further discussion, particularly regarding American species).
