Etymology: Iberochondrostoma: Name referring to the Iberian Peninsula where the genus is distributed.
Eponymy: There is little prospect of finding out who or what is referred to here! The original text does not help, plus there is the fact that originally Steindachner spelt the binomial as leminingii -presumably in error and not by design? (Ref. 128868), visit book page.

初熟時的長度 / 大小 / 重量 / 年齡
成熟度: Lm 4.3, range 4 - 4.5 cm
Max length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556); common length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556)
Diagnosed from its congeners by having usually 49-59 + 2-3 scales on the lateral line, 4½-7 scale rows between lateral line and pelvic origin, and eye diameter 1.0-1.5 times snout length (Ref. 59043).
Body shape (shape guide): elongated.
Adults occur in the middle reaches of streams with moderate current and abundant aquatic vegetation (Ref. 59043) and in the lower reaches of rivers with slow current and abundant submerged plants (Ref. 26100). They feed on invertebrates, plants (Ref. 26100) and zooplankton (Ref. 59043). Spawning occurs from March to May. Threatened due to water abstraction and the introduction of other species (Ref. 26100).
居住於河的中下游的一種生命期短的種, 且水流和緩水平面下植物豐盛的地方。 吃無脊椎動物與植物。 從三月到五月產卵。 受到威脅的由於水資源減少與其他魚種的引入.(參考文獻 26100)
