  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...

Abstract 

28 species of spider are newly recorded from Anguilla, a United Kingdom Overseas Territory, in the Lesser Antilles, including seven also new to science: Agyneta anguilla Sherwood, Mukhida & Connor sp. nov. (Linyphiidae), Sphecozone sandyground Sherwood, Mukhida & Connor sp. nov. (Linyphiidae), Mimetus antillensis Sherwood, Mukhida & Connor sp. nov. (Mimetidae), Modisimus anguillensis Sherwood, Mukhida & Connor sp. nov. (Pholcidae), Anelosimus blackgardens Sherwood, Mukhida & Connor sp. nov. (Theridiidae), Anelosimus covepond Sherwood, Mukhida & Connor sp. nov. (Theridiidae), and Coleosoma roadsalt Sherwood, Mukhida & Connor sp. nov. (Theridiidae). The remaining 18 species representing new faunistic records are: Hibana tenuis (L. Koch, 1866) (Anyphaenidae), Alpaida dominica Levi, 1988 (Araneidae), Eriophora ravilla (C. L. Koch, 1844) (Araneidae), Gea heptagon (Hentz, 1850) (Araneidae), Neoscona oaxacensis (Keyserling, 1864) (Araneidae), Cheiracanthium inclusum (Hentz, 1847) (Cheiracanthiidae), Hogna cf. sanctivincenti (Simon, 1898) (Lycosidae), Pardosa portoricensis Banks, 1901 (Lycosidae), Prolycosides aussereri (Keyserling, 1877) (Lycosidae), Ischnothyreus peltifer (Simon, 1892) (Oonopidae), Peucetia viridis (Blackwall, 1858) (Oxyopidae), Micropholcus fauroti (Simon, 1887) (Pholcidae), Hentzia antillana Bryant, 1940 (Salticidae), Scytodes sp. (Scytodidae), Nolavia antiguensis (Keyserling, 1880) (Sparassidae), Tetragnatha guatemalensis O. Pickard-Cambridge, 1889 (Tetragnathidae), Coleosoma acutiventer (Keyserling, 1884) (Theridiidae), Coleosoma floridanum Banks, 1900 (Theridiidae), Latrodectus geometricus C. L. Koch, 1841 (Theridiidae), Tmarus cf. vertumus Chickering, 1966 (Thomisidae), and Zosis geniculata (Olivier, 1789) (Uloboridae). The families Anyphaenidae Bertkau, 1878, Mimetidae Simon, 1881, Oonopidae Simon, 1892, and Uloboridae Thorell, 1869 are thereby recorded for the first time from Anguilla.
