  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...

First records of Hippasosa ghost (Jocque & Jocqué, 2017) (Araneae, Lycosidae) outside of the type locality in northwestern Madagascar

Abstract

The Malagasy endemic wolf spider Hippasosa ghost (Jocque & Jocqué, 2017), previously known from a single small patch of sandy habitat adjacent to a permanent lake in the Mariarano Classified Forest in northwestern Madagascar, is recorded from two additional localities with similar habitat along the Mariarano River, 10 km and 45 km from the type locality. These finds indicate the possibility that this highly specialized species could have a larger distribution than originally thought, but also they show the importance of protecting such vulnerable habitats.
