[Ichthyology • 2017] Lampetra soljani • A New Brook Lamprey (Petromyzontiformes: Petromyzontidae) from the southern Adriatic Sea Basin


Lampetra soljani
Tutman, Freyhof, Dulčić, Glamuzina & Geiger, 2017


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.

[Ichthyology • 2014] Valencia robertae • A New Killifish (Cyprinodontiformes: Valenciidae) from southern Greece


Valencia robertae 
Freyhof,  Kärst & Geiger, 2014 

Valencia robertae, new species, from the lower Pinios in northern Peloponnese and Mornos Rivers in southern mainland of Greece is distinguished from V. letourneuxi and V. hispanica by having short lateral bars or vertically elongated small blotches along the midlateral body and an almost triangular anal fin in females, prominent lateral bars between the axial blotch and the caudal-fin base and a long anal fin reaching almost or to the first caudal-fin rays in males larger than 27 mm SL. It is also distinguished by 32 fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region.

Abstract

Eidinemacheilus proudlovei, new species, is described from subterranean waters in the Little Zab River drainage in Iraqi Kurdistan. After the discovery of E. smithi in 1976, E. proudlovei is the second troglomorphic nemacheilid loach found in the Middle East and the second species placed in Eidinemacheilus. Eidinemacheilus proudlovei is distinguished from E. smithi by having 8+8 or 8+7 branched caudal-fin rays, no adipose keel on the caudal peduncle, enlarged jaws and a fully developed head canal system. It furthers differs substantially in its DNA barcode (>8% K2P distance) from all other nemacheilid loaches in the Middle East, Europe and Western India.

Eidinemacheilus proudlovei is the name given by researchers from IGB and ZMFK to the new species of fish they described together with colleagues from Kurdistan.

Etymology. Named for Graham Proudlove (Manchester Museum, the University of Manchester), a world expert on subterranean fishes, for his continuous efforts documenting the diversity of troglomorphic fishes.

[Ichthyology • 2016] Sasanidus, A New Generic Name for Noemacheilus kermanshahensis Bănărescu & Nalbant, with discussion of Ilamnemacheilus and Schistura (Teleostei; Nemacheilidae)

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).
