Squalius namak, a new chub from Lake Namak basin in Iran (Teleostei: Cyprinidae)

Abstract

Squalius namak, new species, from the endorheic Lake Namak and Kavir basins in Iran, is distinguished from the species of the genus Squalius in the Persian Gulf and the southern Caspian Sea basins by having a wide and thick symphysial knob on the lower jaw, a convex posterior anal-fin margin, a bold, dark-grey or brown, roundish or crescent-shaped blotch at the posterior tip of each flank scale and orange caudal-, anal- and pelvic-fin rays in life. Squalius namak is also characterized by four fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region.

Capoeta ekmekciae Turan, Kottelat, Kirankaya & Engin, 2006, a junior synonym of Capoeta capoeta (Güldenstädt, 1773) (Teleostei: Cyprinidae)

“…2019), and Squalius orintale from the Caspian Sea basin and S. turcicus from the Çoruh River basin share identical COI genes (Khaefi et al . 2016). Therefore, two allopatric species, that is, the C. ekmekciae and C. capoeta forms, have perhaps recently been isolated.…”

Length-weight and length-length relationships for three species of Squalius (Cyprinidae; Leuciscinae) from the Caspian Sea, Namak and Tigris basins of Iran

“…In this study, the parameters of the length–weight and length‐length relationships are reported for three species of Squalius from different basins of Iran. A newly described species is including in the study ( Squalius namak ), which was previously considered to belong to the Squalius cephalus group (Khaefi, Esmaeili, Sayyadzadeh, Geiger, & Freyhof, ).…”
