Capoeta caelestis, a new species from Goksu River, Turkey (Teleostei: Cyprinidae)

摘要

Capoeta caelestis, new species, from Goksu drainage, southern Anatolia, is distinguished from other Anatolian Capoeta by having a weak and slender last simple dorsal-fin ray without serrae on its posterior margin and 60-68 total lateral line scales. Since the reviews of the Middle East cyprinid genus Capoeta by Karaman (1969) and Banarescu (1999), two new species of the C. tinea and one of the C. capoeta species groups were described (Turan et al, 2006a,b). Turan et al. (2008a) and Ozulug & Freyhof (2008) each described a new species of the C. trutta species group. In 2007, we (MO, JF) collected fishes from the Goksu River in Anatolia, that drains to the Mediterranean Sea east of the city of Antalya. This species has been identified as C. angorae byKiicuk et al. (2007) in their study on the fishes of Goksu. While fishes from Goksu are superficially similar to C. angorae, it was already obvious in the field that they are distinguished at least by the head shape and the lack of serrae on the last unbranched dorsal-fin ray. Capoeta angorae and the species from Goksu belong to a group of superficially similar, almost plain brown, slightly compressed species with narrow lips (C. angorae, C. bergamae, C. damascina, C. kosszvigi, C. umbla). While working on the species from Goksu, Turan (2008) presented molecular results including also the Capoeta from Goksu strongly supporting our result that the Capoeta from Goksu represents a distinct species, which is described here.
