Etymology: Pseudochondrostoma: Name refers to its morphological similarity with the genus Chondrostoma as a consequence of homoplasy in multiple traits.
Eponymy: Heinrich Moritz Willkomm (1821–1895) was a German botanist and academic who collected (1844–1845 & 1850–1851) and studied the flora of Spain and Portugal, where this cyprinid occurs. [...] (Ref. 128868), visit book page.

Diagnosed from its congeners by having the following characters: slightly arched lower jaw edge; 56-71 + 3-4 scales on lateral line; anal fin with 9-10½ branched rays; 26-35 gill rakers; usually 7-6 pharyngeal teeth; and caudal peduncle depth 2.2-2.4 times in its length (Ref. 59043).
Body shape (shape guide): fusiform / normal.
Adults are found in the middle stretches of rivers, in areas with current and also frequently in still water. They occur in groups, especially during pre-reproduction migration (Ref. 59043). A long-lived species which also inhabits water bodies on low plains (Ref. 26100). Adults feed on invertebrates, plants and detritus (Ref. 59043). Spawning takes place in April. Threatened due to pollution and the introduction of other species (Ref. 26100). Max. length (Alejandro Ramos, pers. comm., 2002).
