Etymology: guercifensis: The species name guercifensis was selected, as because the species is mainly distributed around the Guercif village in Morocco (Ref. 107618).
Environment: milieu / climate zone / depth range / distribution range

Morphology | Morphometrics
soft rays: 8;
Vertebrae: 39 - 41. Diagnosis: This species differs from other Luciobarbus species by the following combination of characters: 45-48 scales along the lateral line, 6.5-8.5 scales above lateral line, and 5.5 scales below lateral line; the last single ray of the dorsal fin is strongly ossified with the maximum width 6.2-9.2% of its length; the last single dorsal fin ray is densely denticulated along its length, and, in adult specimens, the number of denticulations exceeds 25; the ethmoid bone is wider than its length; most specimens possess a single pharyngeal tooth in the inner row; the number of vertebrae is 39-41; the interorbital distance is 1.7-2.2 times the eye diameter; the caudal peduncle is longer than the one seen in Luciobarbus nasus, with depth 2.1-2.6 times the length of the anal peduncle; and the posterior segment, manubrium, of the lachrymal bone is short and high (Ref. 107618).
Found in large rivers, mainly in mid-stream, usually in riffle areas (Ref. 107618). It is a rare species that has been found in few places (Ref. 107618).
