  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 Review of the Relationships of Australian Funnel-Web Spiders with a New Species of Funnel-Web Spider from Far North-Eastern Tasmania (Hexathelidae: Atracinae: Araneae)

Abstract

A new species of funnel-web spider, Hadronyche simonfearni, is described from far north-eastern Tasmania. The family status is reviewed. Shortcomings including misidentifications and absence of supporting procedures in molecular analyses placing Atracidae as sister group to the Actinopodidae are identified and solutions proposed. The use of unanalysed venom data of the Atracidae in proposing relationship is rejected. The diagnoses of Macrothelidae and Porrhothelidae, as well as that of the Atracidae are rejected as non-diagnostic. They are the closest relatives to each other, as shown by repeated morphological analyses, with further doubt being cast upon limited molecular analyses through misidentifications. The Atracinae are replaced in the Hexathelidae and the Macrothelidae and Porrhothelidae placed in the Macrothelinae, also in the Hexathelidae. New genera and a subgenus proposed by Hoser (2017) are rejected.
