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 based on various aspects such as morphology, burrow architecture, behaviour and habitus: Nemesia eira n. sp. from Cádiz province, N. gajui n. sp. from Córdoba municipality, N. socohina n. sp. from Guadalcázar, Córdoba, and N. ripolli n. sp. from Cártama, Málaga. In addition to the traditional diagnostic characters, this study discusses the dispersion ability, distribution, as well as the taxonomic status of the nominal species N. ariasi Simon, 1914 from Morocco and N. macrocephala occidentalis Frade & Bacelar, 1931 from Guadalajara and Valencia, Spain.
