Mostar minnow

Phoxinellus pseudalepidotus has a broad, dark stripe running from the eye to base of the caudal fin, this sits within a pigmented area on the back and flanks. The dorsal and anal fins both have 7+1⁄2 branched rays. The snout is blunt and clearly rounded with a subterminal mouth. The body is largely scale-less but there are 54-77 scales in the lateral line and a few scales above and below the lateral line to the rear of the head. This species has a maximum standard length of 10.3 cm (4.1 in).

Phoxinellus pseudalepidotus is only known from the Mostarsko Blato, a polje in the Dinaric Karst region of southern Bosnia and Herzegovina, where it is found in the middle and lower reaches of the Lištica River, as well as a series of associated springs, tributaries and subsurface water bodies. The Mostar minnow occurs in shallow channels with a slow current and clear water.

Phoxinellus pseudalepidotus is the type species of the genus Phoxinellus. This name is a diminutive of Phoxinus, the genus of the "true" Eurasian minnows. Heckel may have coined this name due to the small size of P. alepidotus when compared to Cyprinus phoxinus. The specific name, pseudalepidotus, prefixes pseud-, which means "false", onto the specific name of the type species of Phoxinellus, P, alepidotus, to indicate that this species is similar but not the same as that species.
