Issue
This species is questionably a junior synonym of Eudontomyzon mariae (Berg, 1931) in Renaud (2011; Re. 89241:41). Please send references, or more studies are needed. Considered a subspecies of Eudontomyzon mariae by authors (Ref. 12283).

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 0. With 61 - 67 trunk myomeres; trunk not mottled in live ammocoetes. The caudal fin is hyaline, of a spade-like shape.
具有 61- 67 軀幹 myomeres; 軀幹不是有斑點在活的 ammocoetes 中。 尾鰭是透明的,像鏟子一樣形狀。
Adults inhabit clear, well-oxygenated brooks in piedmont and mountain zones. They are non-parasitic and remain in freshwater. Ammocoetes live in detritus-rich sands or clay sediments. Ammocoete stage lasts 3.5-4.5 years. Ammocoetes feed on detritus and micro-organisms. They metamorphose in July - September and spawn in March - May. Males dig shallow nests in habitats with moderate currents (Ref. 59043). Males and females die after spawning.
成魚棲息於清澈的, 在 piedmont 與山區域中的溶氧量高的小溪; 他們是非寄生而且逗留在淡水。 Ammocoete 階段持續 3-4 年; 仔魚以碎屑與微為食-生物。 他們在七月變形 - 九月而且產卵於三月中 - 五月。 雄性挖在棲息地的淺灘巢且水流平穩的地方.(參考文獻 59043) 雄性與雌性在產卵之後死亡。

Males dig shallow nests in habitats with moderate current. Spawning occurs when temperature reach 7-10°C at higher elevations (Ref. 59043).歐洲: Donau 與它的支流。 被認為是一個 烏克蘭雙齒七鰓鰻〔Eudontomyzon mariae〕 的亞種由命名者了。 (參考文獻 12283)
