  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...

Identity check: documenting the type specimens of historical Malagasy wolf spiders (Araneae: Lycosidae)

Abstract
This work aims to digitize and disseminate knowledge on historical specimens of Malagasy lycosids, as a foundation for future researchers intending to undertake a comprehensive review of this fauna. The types of Arctosa atroventrosa (Lenz, 1886), Geolycosa nossibeensis (Strand, 1907), Hippasosa fera (Strand, 1907), and Trochosa urbana hova Strand, 1907 were examined, figured, and their taxonomic identities discussed herein. Arctosa atroventrosa is proposed as a nomen dubium. Geolycosa nossibeensis is clearly misplaced in Geolycosa Montgomery, 1904 and is transferred to Trochosa C. L. Koch, 1847 as Trochosa nossibeensis comb. nov. Likewise, H. fera is a valid species but is misplaced in Hippasosa Roewer, 1960 and does not belong to this genus. Trochosa urbana hova, recently synonymised with the nominal species is confirmed in its current taxonomic placement. Lycosa madagascariensis Vinson, 1863 is treated as a species inquirenda as the types cannot be located but the mention of specific localities in Madagascar could allow future workers to designate a neotype to recognise this species. Lycosa signata Lenz, 1886 is treated as a valid species, although a neotype designation will be required in future as the holotype was destroyed as a result of bombing raids on the Museum of Lübeck during the World War II and its vulva never previously illustrated.
