Atlantor, a new generic name for Barbus reinii Günther, 1874 from Morocco(Teleostei: Cyprinidae).

Atlantor, new genus, is proposed for Barbus reinii from the Atlantic basin in Morocco. The sole species of the genus is clearly separated from related genera based on its phylogenetic position, and from Carasobarbus, Mesopotamichthys and Pterocapoeta in its morphological characters. Atlantor was previously included in Labeobarbus, making this genus paraphyletic with respect to several genera from Western Asia and North Africa. With the description of Atlantor, all these genera become monophyletic. Within Torinae, Atlantor can be diagnosed by having 5½ branched anal-fin rays, modally 8½ branched dorsal-fin rays, two pairs of long barbels, and by its distinct phylogenetic position.

Revision of the Garra species of the Hajar Mountains in Oman and the United Arab Emirates with the description of two new species (Teleostei: Cyprinidae).

The Garra species inhabiting the Hajar Mountains are revised and five species are recognised, two of which are newly species described herein. Garra barreimiae, from the United Arab Emirates (UAE) and Northern Oman, is distinguished from other Garra species in the Hajar Mountains by a strongly mottled flank pattern with individual or series of midlateral orange scales, a white dorsal-fin tip, an orange spot at the upper operculum, and more gill rakers on the lower limb of the first gill arch. Garra barreimiae shawkahensis is a synonym of G. barreimiae. Garra gallagheri, from the Wadi Bani Khalid drainage in Oman, is distinguished by flank-scale margins the same colour or slightly darker than the centre of the scales. Garra longipinnis, from the interior wadis in the Central Hajar Mountains in Oman, is distinguished by flank-scale margins being clearly darker than the centre of scales. The original description of G. longipinnis was based on a few individuals with very large fins, which are here considered aberrant. Garra shamal, new species, from the coastal drainages around Muscat in Oman, is distinguished by a strongly mottled flank pattern usually without orange midlateral scales, a white dorsal-fin tip, no orange spot at the upper operculum, and middle caudal-fin rays and membranes the same colour or slightly darker than the rest of the fins in colouration. Garra sharq, new species, from the Wadi Kabbah drainage and a few interior springs in Oman, is distinguished by a strongly mottled flank pattern with individual or series of orange midlateral scales, no orange spot at the upper opercle, and dorsal-fin tip and membranes between central caudal-fin rays the same colour as the rest of the fins. All five species are well differentiated genetically and form distinct mitochondrial clades with between 2.1 and 9.2% differences (p-distances) in the mitochondrial COI.

Molecular phylogeny of the tribe Torini Karaman, 1971 (Actinopterygii: Cypriniformes) from the Middle East and North Africa.

Freshwater fishes of the cyprinid tribe Torini are widespread in Africa the Middle East and Indomalaya. The relationships of Middle-Eastern Torini are analysed based on mitochondrial markers (Cyt b, ND4) of the majority of relevant species. I present a larely well resolved phylogeny, which confirms the validity of the morphologically defined genera Arabibarbus, Carasobarbus, Mesopotamichthys and Pterocapoeta. The Torini originated in Indomalaya and colonised Africa via the Middle East. Morocco was colonised two times independently, first from sub-Saharan Africa and secondly along the southern margin of the Mediterranean Sea. The Tigris-Euphrates system is an important crossroad for the colonisation of the Jordan River, the Orontes River and the watercourses of the Arabian Peninsula by freshwater fishes. The Jordan lost its connection to the Euphrates earlier than the Orontes. The Arabian Peninsula was colonised from the Tigris-Euphrates system in at least two independent events.

Taxonomic revision of the genus Carasobarbus Karaman, 1971 (Actinopterygii, Cyprinidae).

Representatives of the fish genus Carasobarbus Karaman, 1971 (Actinopterygii: Cyprinidae) from the Middle East and North Africa were previously placed in 14 different genus-group taxa (Barbellion, Barbus, Barynotus, Capoeta, Carasobarbus, Cyclocheilichthys, Kosswigobarbus, Labeobarbus, Luciobarbus, Pseudotor, Puntius, Systomus, Tor and Varicorhinus). The generic assignment of several species changed frequently, necessitating a re-evaluation of their taxonomic status. In this study, the genus Carasobarbus is revised based on comparative morphological examinations of about 1300 preserved specimens from collections of several museums and freshly collected material. The species Carasobarbus apoensis, Carasobarbus canis, Carasobarbus chantrei, Carasobarbus exulatus, Carasobarbus fritschii, Carasobarbus harterti, Carasobarbus kosswigi, Carasobarbus luteus and Carasobarbus sublimus form a monophyletic group that shares the following combination of characters: medium-sized barbels with a smooth last unbranched dorsal-fin ray, nine or 10 branched dorsal-fin rays and six branched anal fin-rays; scales large, shield-shaped, with many parallel radii; the lateral line containing 25 to 39 scales; the pharyngeal teeth hooked, 2.3.5-5.3.2 or 2.3.4-4.3.2; one or two pairs of barbels. The species are described in detail, their taxonomic status is re-evaluated and an identification key is provided. A lectotype of Systomus luteus Heckel, 1843 is designated. Carasobarbus Karaman, 1971, Kosswigobarbus Karaman, 1971, and Pseudotor Karaman, 1971 are subjective synonyms, and acting as First Reviser we gave precedence to the name Carasobarbus.
