  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 tiny tarantulas of the genus Thalerommata Ausserer, 1875 (Araneae, Theraphosidae) from northern Colombia


Abstract

Thalerommata Ausserer, 1875 is a theraphosid genus with very small species that resemble Trichopelma, although they lack the dot pattern on the abdomen. They are also distinguished from all other Theraphosidae by the presence of flattened, iridescent setae covering the abdomen, and sometimes, the legs too. Its current distribution includes the following countries: Argentina, Bahamas, Colombia, Cuba, Jamaica and Venezuela. Three new species of tiny tarantulas of the genus Thalerommata are described from northern Colombia: Thalerommata yukpa sp. nov. from Cesar Department, Thalerommata kogui sp. nov. and Thalerommata margarita sp. nov. from Magdalena Department. Colombia has now seven of the thirteen Thalerommata species.
