  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...

Six new species of Pandercetes L. Koch, 1875 (Araneae: Sparassidae: Heteropodinae) from Southeast Asia

Abstract

Six new species, Pandercetes batak sp. nov. (♂♀), P. barisanensis sp. nov. (♀; both from Sumatra, Indonesia), P. cheemai sp. nov. (♂♀; Laos), P. mindanaoensis sp. nov. (♂; Philippines, Mindanao), P. jaegeri sp. nov. (♀) and P. bataanensis sp. nov. (♀; both from Philippines, Luzon) are described. The genus is recorded from Laos, Philippines and Sumatra for the first time. The discovery of P. cheemai sp. nov. represents the northernmost record for the genus range. Genus Pandercetes is re-diagnosed. For two species, P. longipes Thorell, 1881 and P. peronianus (Walckenaer, 1837), the distribution data listed in the World Spider Catalog was found to be inaccurate and has now been revised. Detailed descriptions, digital photographs and a distributional map of all new species are provided.
