Proterebia phegea (Borkhausen, 1788) (Lepidoptera: Nymphalidae: Satyrinae) is a butterfly with a restricted and fragmented distribution in the Balkan Peninsula. During a field trip on 26.iv.2022, within the area of the artificial Vau-Dejës Lake in northern Albania, the first author observed one female of P. phegea. The butterfly was found in a forest habitat on sandy, dark-reddish ophiolite rocky substrate. Twenty butterfly species were recorded in that area during the field trips, between March 2021 to September 2022, including Hipparchia fagi (Scopoli, 1763) occurring together with Hipparchia syriaca (Staudinger, 1871), Hipparchia statilinus (Hufnagel, 1766), and ten species of Odonata. This is only the second locality in Albania where P. phegea has been found. These two distant localities form a bridge between the well-documented populations of Croatia, Bosnia-Herzegovina, and Greece. The dragonfly, Trithemis annulata (Palisot de Beauvois, 1807) is new for northern Albania. The known and potential distribution, phenology and conservation status of P. phegea in Albania are discussed.

13 páginas, 8 figuras, 1 tabla., [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., [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., Financiación para este proyecto de investigación: Ministerio de Ciencia e Innovación (CGL2007-60516/BOS) para Roger Vila y Vlad Dincă, beca predoctoral de la Universitat Autònoma de Barcelona para Vlad Dincă, y subvenciones de NSERC y Genome Canada para Paul D.

Pseudophilotes bavius (Eversmann, 1832) is a butterfly species of European conservation concern (listed in Annexes II and IV of the Habitats Directive 92/43/EEC) with a restricted and fragmented distribution. In Romania, where it reaches the north-western limit of its range, P. bavius has disjunct populations: Transylvania in the north-west and Dobrogea in the south-east, with a gap of about 400 km between the two. In this study we provide an overview on the distribution of P. bavius in Dobrogea, while reporting three new sites which double the number of known localities and extend the species’ distribution about 60 km north in this region. The known and potential distribution, habitat, phenology and conservation status of P. bavius in Dobrogea are discussed., Support for this research was provided by the Ministerio de Ciencia e Innovación project (CGL2007-60516/BOS), and a predoctoral fellowship from Universitat Autònoma de Barcelona to V.
