How to ensure a species remains in oblivion: the history of Nemesia hispanica L. Koch, 1871 (Araneae: Mygalomorphae: Nemesiidae)

  How to ensure a species remains in oblivion: the history of Nemesia hispanica L. Koch, 1871 (Araneae: Mygalomorphae: Nemesiidae) Abstract The taxonomic history of Nemesia hispanica L. Koch 1871 is revised; it is a species long affected by misidentifications since 1871. New material from Monte Abantos, San Lorenzo de El Escorial, Madrid (Spain) is analyzed, providing the first descriptions of males, adult females, and burrow structure—particularly relevant given that the holotype seems to be an immature specimen. Morphology of copulatory organs and the distinctive burrow architecture allow clear differentiation from other morphologically related species. Finally, the historical chain of misidentifications is examined, along with its implications for Iberian nemesiid diversity and taxonomy. Pertegal, C., Narro, A. & Olivares, P.
