Length-weight and length-length relationships are presented for three endemic Pseudophoxinus species in Turkey. This study provides the first references for these relationships in the species examined.
Three new species of the genus Pseudophoxinus are described from Turkey. Pseudophoxinus elizavetae sp. n. is distinguished from all other species of the genus by having terminal mouth; eye diameter less than snout length; lateral line incomplete, narrowly interrupted on caudal peduncle, number of lateral line scales 42-60; scales in lateral series 60-68; number of gill rakers 11-13; total vertebrae (36)37; caudal vertebrae 15(16); no lateral stripe in alive individuals. Pseudophoxinus zekayi sp. n. differs in terminal mouth; eye diameter markedly greater than snout length; lateral line complete, number of lateral line scales 37-42; number of gill rakers 8; total vertebrae 36-37; caudal vertebrae 15-16; no lateral stripe in alive individuals. Pseudophoxinus firati sp. n. is distinguished by dorsal fin with commonly 4 simple rays; subterminal mouth; eye diameter less than snout length; back markedly humped; lateral line complete or slightly incomplete (narrowly interrupted on caudal peduncle); number of lateral line scales 15-44; scales in lateral series 45-51; number of gill rakers 6-7, rarely 8; total vertebrae 37-38(39); caudal vertebrae 16-17; deep dark lateral stripe in alive individuals. A comparison with other species of Pseudophoxinus s. str. from Turkey and the type species of the genus, P. zeregi, is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
