  Hidden diversity in plain sight: four new species of Nemesia (Araneae: Mygalomorphae) from the Córdoba Province of Spain Abstract A taxonomic revision of the species of Nemesia Audouin, 1826, distributed in the vicinity of Córdoba City, southern Spain, is presented. Four new species are described: Nemesia morana sp. nov. (female), N. kodama sp. nov. (male and female), N. rosae sp. nov. (male and female), and N. tamajoni sp. nov. (male and female). These species are distinguished by distinct morphological characters, including the shape of the spermathecae, palpal bulbs, and spinnerets, as well as by burrow architecture. Fieldwork was conducted across two of the three major habitat types in the region—the humid, forested mountains of Sierra Morena and the croplands and riparian forests of the Guadalquivir Valley—while the third, the “campiña”, which is mainly composed of agricultural landscapes, remains poorly explored. Sampling methods included pitfall trapping and the direct e...

Three new species of Androctonus from Morocco (Arachnida: Scorpiones: Buthidae)

Abstract


New data are presented on the taxonomy and distribution of the dark species of the genus Androctonus Ehrenberg, 1828 in Morocco and Western Sahara. Three new species, A. argoubi sp. n., A. stockmanni sp. n., and A. vaneki sp. n. from Morocco are described, characterized by having metasoma I–IV ventrally punctate, a character that is well developed in A. stockmanni sp. n., and A. vaneki sp. n., and weakly developed in A. argoubi sp. n. Dark species from Morocco are compared with A. sergenti Vachon, 1948, and A. bourdoni Vachon, 1948. We describe and compare their external morphology, illustrating their characters comprehensively in color photographs. The hemispermatophores of two species are described and illustrated, and a map showing the distributions of the studied species is provided. Furthermore, for all three newly described species, we provided their karyograms, which are very similar (2n = 24) and demonstrate the karyotypic uniformity of the entire genus Androctonus.
