Description of an unexpected troglobitic species of the genus Lithobius Leach, 1814 from a Pyrenean cave in France, with a synthesis on the troglobitic centipedes from Pyrenees (Myriapoda: Chilopoda)

&
 

Summary

New information on several Pyrenean troglobitic species of centipedes is given in this paper. A new species of the genus Lithobius is described: L. poneli Iorio, n. sp., found in the cave Grotte de Haiouat de Pelou (Hautes-Pyrénées). Lithobius allotyphlus Silvestri, 1908 has been found again in France after 71 years, and the only previous quotation of this species in Spain probably refers to L. typhlus Latzel, 1886. A syntype of L. reiseri Verhoeff, 1900 is examined and additional details are described for it. The Spanish species quoted as L. reiseri in the past belongs to another species, probably new but further research is necessary and it is tentatively named here “Lithobius sp. of Guipúzcoa”. A distribution map is included for each troglobitic Pyrenean endemic quoted in France, together with the bibliography. An identification key is proposed for several Lithobius rather close morphologically. A checklist of the currently known troglobitic centipedes in the Pyrenees and/or their surroundings is given.

Résumé

Description d'une espèce troglobie inattendue du genre Lithobius Leach, 1814 d'une grotte pyrénéenne en France, avec une synthèse sur les centipèdes troglobies des Pyrénées (Myriapoda : Chilopoda). Des données nouvelles sont fournies sur plusieurs espèces de chilopodes troglobies des Pyrénées. Une nouvelle espèce du genre Lithobius est décrite : L. poneli Iorio, n. sp., trouvé dans la Grotte de Haiouat de Pelou (Hautes-Pyrénées). Lithobius allotyphlus Silvestri, Citation1908 a été retrouvé en France après 71 ans sans aucune récolte, tandis que l’unique citation de cette espèce en Espagne se réfère probablement à L. typhlus Latzel, Citation1886. Un syntype de L. reiseri Verhoeff, Citation1900 est examiné et des éléments complémentaires sont décrits sur lui. L’espèce espagnole citée sous L. reiseri dans le passé appartient en réalité à une autre espèce, probablement nouvelle ; mais d’autres recherches seront nécessaires. Elle est nommée provisoirement “Lithobius sp. de Guipúzcoa”. Une carte de répartition est incluse pour chaque troglobionte endémique pyrénéen cité en France, en incluant la bibliographie. Une clé d’identification est proposée pour plusieurs Lithobius assez proches morphologiquement. Une liste des chilopodes troglobies actuellement connus dans les Pyrénées et/ou à leurs abords immédiats est donnée.
