Biogeography, ecology and conservation ofErebia oeme(Hübner) in the Carpathians (Lepidoptera: Nymphalidae: Satyrinae)

Abstract

[FR]L’espèce endémique Européenne, Erebia oeme (Hübner [1804]) (Lepidoptera: Nymphalidae: Satyrinae), a été découverte dans la Chaîne des Carpates d’où elle était considérée comme absente. La seule population trouvée se situe dans la partie méridionale des Carpates Roumaines (Massif du Retezat), où l’espèce est sympatrique et synchronique avec Erebia medusa ([Denis & Schiffermüller] 1775). La similarité morphologique externe entre ces deux espèces est probablement la raison pour laquelle E. oeme a été méconnu dans les Carpates ce qui a laissé un défi cit d’information inattendu au niveau du continent Européen ayant fait l’objet d’études approfondies. La morphologie des spécimens Roumains est comparée aux populations du reste de l’aire de répartition de cette espèce et avec E. medusa. D’autre part nous avons testé le codage à barres de l’ADN comme méthode pour identifi er ces deux espèces et avons confi rmé que ceci est en effet un outil effi cace d’identifi cation pour les taxons concernés. L’habitat d’ E. oeme, les adultes des deux sexes et leurs organes génitaux sont illustrés en comparaison à E. medusa. Basé sur l’étude de différentes collections, nous démontrons que E. oeme est probablement très local dans les Carpates et nous apportons des arguments pour considérer l’espèce comme vulnérable en Roumanie.

[EN]The European endemic Erebia oeme (Hübner [1804]) (Lepidoptera: Nymphalidae: Satyrinae) is discovered in the Carpathian Chain, from where it was considered to be absent. The single population found is situated in the southern part of the Romanian Carpathians (Retezat Mountains), where it fl ies sympatrically and synchronically with Erebia medusa ([Denis & Schiffermüller] 1775). The similar external morphology of these two species probably caused E. oeme to be overlooked in the Carpathians, leading to an unexpected information gap in the otherwise thoroughly studied European continent. The morphology of the Romanian specimens is compared to populations from the rest of the species’ range and to E. medusa. In addition, we tested DNA barcoding as a method to discriminate between these species and confi rmed that it represents an effective identifi cation tool for the taxa involved. The habitat of E. oeme, adults of both sexes and their genitalia are illustrated in comparison with E. medusa. Based on the study of several collections, we show that E. oeme is likely to be extremely local in the Carpathians and provide arguments to consider the species as vulnerable in Romania.
