  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...

A new species of the lyrate curtain-web spider genus Trechona C. L. Koch, 1850 from South Brazil and the hitherto unknown female of T. excursora (Araneae: Dipluridae)

Abstract

A new species of the lyrate curtain-web spider genus Trechona C. L. Koch, 1850, Trechona minuana sp. nov., is described, based on males and females from Santa Catarina state, South Brazil. It is the first species of the genus from this Brazilian region. Additionally, we describe for the first time the female of Trechona excursora Pedroso, Miranda & Baptista, 2019 based on specimens from its type localities.
