DOI: 10.3897/zse.100.118612

Abstract

Oxynoemacheilus chaboras, new species, from the stream Beyazsu in the Euphrates drainage, belongs to the O. persa species group, being closely related to O. shehabi from the Orontes, O. sarus from the Seyhan and Ceyhan, O. euphraticus from the Euphrates and Tigris, O. karunensis from the Karkheh, and O. persa from Central Iran. The new species is distinguished from others in the O. persa group by having 8–9 pores in the supraorbital canal, two distinct black blotches at the caudal-fin base, a rudimentary and shallow pelvic axillary lobe, 6–10 irregularly shaped bars on the flank, and a deep head, body, and caudal peduncle. Oxynoemacheilus chaboras sp. nov. is most closely related to O. euphraticus, from which it is differentiated by a mean uncorrected p-distance of 3.24% (min. 3.09%) in its COI barcode gene.

 Oxynoemacheilus nasreddini

Yoğurtçuoğlu, Kaya & Freyhof, 2021

DOI: 10.11646/zootaxa.4974.1.5

Abstract

Oxynoemacheilus nasreddini, new species, from Lake Akşehir, Eber, Eğirdir, and Ilgın basins in Central Anatolia is distinguished from other species of Oxynoemacheilus in Central Anatolia by having irregularly shaped blotches on flank; 2–4 dark-brown bands on caudal fin; a slender body, and an emarginate caudal fin in which the shortest middle caudal-fin ray is 76–91% of the longest ray of the upper caudal-fin lobe. Molecular data suggest that the new species is closely related to O. mediterraneus from the Aksu and Köprüçay drainages. Although the two species are separated by only a minimum K2P distance of 1.2% in the mtDNA COI barcode region, they are well distinguished morphologically. The situation is complicated by loaches from Lake Eğirdir basin that are identified as O. nasreddini by their morphological character states but are only distinguished from O. mediterraneus by a minimum K2P distance of 0.2% in the mtDNA COI barcode region.

Abstract

The Glyptothorax species inhabiting the Euphrates and Tigris drainages are reviewed and six species are recognised, one of which is described herein as new species. Glyptothorax armeniacus is endemic to headwater streams in the Euphrates drainage. Glyptothorax kurdistanicus is endemic to the upper Tigris downstream to the Lesser Zab drainage. Glyptothorax cous and G. steindachneri are riverine species widespread in both the Euphrates and Tigris drainages. Glyptothorax silviae is endemic to Iran. Glyptothorax daemon, new species, from the Greater Zab and Yanarsu in the upper Tigris drainage, is distinguished by having the thoracic adhesive apparatus strongly elevated, 1.1–1.2 times longer than wide, without tubercles on the head, well developed anteromedial striae, the medial pit without striae, and a short adipose fin. Glyptothorax daemon is separated into two mitochondrial lineages, externally indistinguishable and separated by a minimum K2P distance of 2.0% in the DNA barcode region. These lineages are paraphyletic in our analysis indicating past introgressive hybridisation with G. cous. All six species are diagnosed and all, except unstudied G. steindachneri, form distinct mitochondrial clades with between 1.2% and 3.4% minimum K2P distance between them. Species from the Euphrates and Tigris form a monophyletic mitochondrial group separated from 53 other Glyptothorax species studied from India and areas further east.

 DOI:  10.11646/zootaxa.4273.4.4 

Abstract

Lampetra soljani, new species, is described from the lower Neretva River in the Adriatic Sea basin. Previously it was identified as L. zanandreai. Based on morphological similarity and mitochondrial genetic data, it is related to L. lanceolata and L. ninae from the Black Sea basin. Lampetra soljani is distinguished from all other species of Lampetra by having a marmorate flank pattern in live, fully grown ammocoetes, and in some adults (vs. plain colour pattern). Lampetra soljani is distinguished from other Lampetra species by having three velar tentacles, 54–57 trunk myomeres between the last branchial opening and the anus, no posterial teeth and a bicuspid middle endolateral tooth. Lampetra soljani is also well distinguished by COI barcode data from its congeners. The new species is widespread in the Neretva River drainage and lampreys from Lake Skadar basin are likely to belong to this species also.

 DOI: 10.11646/zootaxa.4107.1.3  

Abstract

Sasanidus, new genus, is described for Noemacheilus kermanshahensis Bănărescu & Nalbant, endemic to the Karkheh and Karun drainages in Iran. Sasanidus kermanshahensis was initially identified as a species in Oxynoemacheilus, from which it is distinguished by the absence of an external sexual dimorphism (i.e. longer pectoral fin, and nuptial tubercles on fins, head and back in males). Sasanidus is distinguished from all other genera of Nemacheilidae in the Middle East by a combination of the following character states: pelvic-fin origin behind of a vertical of the dorsal-fin origin, anus about one eye diameter in front of the anal-fin origin, dorsal adipose keel absent, a high crest on the bony capsule of the swim bladder present and colour pattern marbled or mottled or with an irregularly shaped midlateral stripe. Ilamnemacheilus longipinnis was examined and no difference could be found between Ilamnemacheilus and Oxynoemacheilus. Therefore, Ilamnemacheilus is treated as a synonym of Oxynoemacheilus. COI barcode sequences from all nemacheilid loach genera occurring in the Middle East and western India are analysed jointly for the first time. The view that Schistura is a paraphyletic assemblage is supported by the clustering of DNA sequences from 45 specimens placed in at least 20 species in the genus Schistura analysed here.

Etymology. The genus is named for the Sassanid Empire, which was recognized as one of the leading regional powers for a period of more than 400 years. During Late Antiquity, the Sasanian Empire is considered to have been one of Iran's most important and influential historical periods. Gender masculine.

Distribution. Sasanidus kermanshahensis is known from headwaters of the Karkheh and Dez Rivers. The Dez is a tributary to the Karun and both the Karkheh and Karun flowi from the Iranian Zagros Mountains westwards into the lowermost Tigris (Abdoli 2000).
