  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 Paratropis Simon, 1889 (Araneae: Mygalomorphae: Paratropididae) from Brazil and Colombia

Abstract

The Paratropididae Simon, 1889 comprises small to medium-sized (6.0–18.5 mm) mygalomorph spiders with 26 species distributed in four genera: Anisaspis Simon, 1892; Anisaspoides F. O. Pickard-Cambridge, 1896; Paratropis Simon, 1889 and Stormtropis Perafán, Galvis & Pérez-Miles, 2019. Paratropidids can be found in tropical and mountain forests, in caves, near rivers, under fallen logs and rocks, leaf litter, moss and ravines. Most species are distributed in South America, mainly in Colombia, Ecuador and Brazil. Despite recent efforts in understanding the taxonomy of the family, paratropidids are still poorly studied. Herein, three new species of Paratropis are described: Paratropis celiae sp. nov. and Paratropis manauara sp. nov., both from Manaus in the state of Amazonas, Brazil; and Paratropis vulcanix sp. nov. from Departamento Tolima-Calda Nevado del Ruiz, Colombia. An updated geographical distribution map for the entire genus is presented and a discussion on the taxonomic problems of the family is provided.
