Oxynoemacheilus Muefiti

📖 Overview

Oxynoemacheilus Muefiti (Oxynoemacheilus muefiti), first described by Freyhof, Kaya, Turan & Geiger, 2019 is a small fish in the family Nemacheilidae (order Cypriniformes). Adults typically reach 7.00 cm in maximum length. It inhabits freshwater systems including rivers, streams, and lakes. It occurs in Subtropical waters. It is broadly omnivorous, taking invertebrates, plant matter, and detritus.

🔬 Taxonomy

🐟 Physical Description

This species is distinguished from O. arsaniasus by not having a central pore in the supratemporal canal (vs. present); with mottled colour pattern on the caudal-fin base (vs. a bold bar, usually fused with a roundish or vertically elongate, dark-brown blotch at the vertical midline); fine, brown, mottled colour pattern on the flank, usually organised in narrow, pale-brown bars on the flank behind the dorsal-fin base (vs. flank marmorate, often with a midlateral series of large, bold, dark-brown, very irregularly shaped blotches or short bars); bars on caudal peduncle not separated from the adjacent saddles on the back (vs. separated); narrow, pale-brown, indistinct bands on the caudal fin (vs. usually bands wide, bold and dark-brown). It differs from O. ercisianus by the longer and more slender caudal peduncle, the caudal peduncle length 1.3-1.6 times its depth (vs. 1.0-1.3) in individuals larger than 5.0 cm SL; narrower body, its body width at dorsal-fin origin 11-13% SL (vs. 13-17); a shallow dorsal adipose crest on the caudal peduncle reaching to the vertical through the base of the last anal-fin ray in individuals larger than 5.0 cm SL (vs. higher crest, not reaching to the vertical through the base of the last anal-fin ray base in individuals larger than 5.0 cm SL). It differs from O. hazarensis with suborbital groove in the male absent (vs. present); no scales on the caudal peduncle (vs. with scales); shorter outer rostral barbel, 20-34% HL (vs. 34-41); shorter maxillary barbel, 25-33% HL (vs. 32-40). It differs from O. kaynaki with lateral line incomplete (vs. complete); pelvic axillary lobe absent (vs. present); no scales (vs. present); bold, black bar at the caudal fin origin absent (vs. present). It differs from O. tigris by having a mottled flank pattern without bold bars (vs. 10-16 bold bars, very prominent on the caudal peduncle); bold, black spots at the upper and lower caudal-fin base absent (vs. with 2 bold, black spots in most individuals); no scales (vs. present). It further differs from the other species inhabiting the Euphrates drainage not belonging to the O. tigris species group by the following: distinguished from O. araxensis with suborbital groove in the male absent (vs. present); lacking scales (vs. present); differs from O. argyrogramma, O. bergianus, O. euphraticus, O. samanticus by having a slightly emarginate caudal-fin (vs. deeply emarginate or slightly forked); suborbital groove in the male absent (vs. present); no scales (vs. present), and no black spots at the caudal-fin base (vs. two bold black jet spots in O. argyrogramma, O. euphraticus); differs from O. paucilepis with lateral line incomplete (vs. complete), no scales (vs. flank covered by often isolated scales) .Cross section: oval.
