Revealing new species within a species complex of  Nemesia  Audouin, 1826 (Araneae, Mygalomorphae) trapdoor spiders from Andalusia (Spain)

Four new species of the Nemesia dorthesi group , morphologically similar to Nemesia shenlongi Pertegal, García, Molero-Baltanás & Knapp, 2022, from Andalusia (Spain), are described on the basis of various aspects such as morphology, burrow architecture, behavior and habitus: Nemesia eira n. sp. from the province of Cadiz, N. gajui n. sp. from the municipality of Cordoba, N. socohina n. sp. from Guadalcázar, Cordoba, and N. ripolli n. sp. from Cártama, Málaga. In addition to traditional diagnostic characteristics, this study analyzes the dispersal capacity, distribution, and taxonomic status of the nominate species N. ariasi Simon, 1914 from Morocco and N. macrocephala occidentalis Frade & Bacelar, 1931 from Guadalajara and Valencia, Spain.
