Forty adult specimens of Atypus affinis were collected during one year in Asturias and Cantabria with pitfall traps emptied fortnightly. Specimens were collected in sampling places with different natural and managed plant formations. The captures show the spatial and temporal activity of the males of this species in the Cantabrian area. Their greatest activity was recorded in the first fortnight of December. Knowledge of mygalomorph spiders in the Iberian Peninsula is increasing with new faunal data, the description of new taxa, and the relocation of those already known, especially from the southeast of the Iberian Peninsula and the Balearic Islands. These changes make it necessary to update the Ibero-Balearic catalogue of the infraorder Mygalomorphae. This catalogue includes 39 species from five families. The families Atypidae, Macrothelidae, and Theraphosidae have only one species each, the family Halonoproctidae has two and the family Nemesiidae has 34 in three genera: Amblyocarenum, with one species, Iberesia, with six species and Nemesia, with 27 species.
