title: On the taxonomic placement of the Cuban spider Nops ariguanabo Alayón and the description of a new Mexican Tarsonops (Araneae, Caponiidae).
abstract: The Cuban spider species Nops ariguanabo Alayón, 1986 is transferred to the genus Tarsonops Chamberlin based on the presence of several false sutures on the anterior tarsi and metatarsi, and a broad, subcircular carapace. A redescription of the species, including the description of female internal genitalia is provided. Additionally, a new species of Tarsonops from Mexico is described. The first SEM photos and a new diagnosis for the genus Tarsonops are included.
