  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...

The genome sequence of the snake-back spider, Segestria senoculata (Linnaeus, 1758) (Araneae: Segestriidae)

Abstract

We present a genome assembly from an individual female Segestria senoculata (snake-back spider; Arthropoda; Arachnida; Araneae; Segestriidae). The assembly contains two haplotypes with total lengths of 3 804.19 megabases and 3 893.16 megabases. Most of haplotype 1 (95.27%) is scaffolded into 8 chromosomal pseudomolecules. Most of haplotype 2 (93.96%) is scaffolded into 8 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 14.73 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
