  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...

Two new species and a new synonym of Oedignatha Thorell, 1881 from China (Araneae: Liocranidae)

Abstract

Two new species of Oedignatha Thorell, 1881 are described from China: O. tongbiguan sp. nov. (♂♀) from Yunnan Province and O. zham sp. nov. (♂♀) from Xizang Autonomous Region. Images and detailed descriptions of the habitus and copulatory organs of both species are provided. Moreover, Koppe ninger Chu & Li, 2023 is proposed as a junior synonym of Oedignatha dian Lu & Li, 2023.
