Etymology: Thymallus: Greek, thymallos, -ou = a kind of fish similar to salmon (Ref. 45335); tugarinae: Named for Professor Polina Yakovlevna Tugarina, Irkutsk State University.
Eponymy: Praskov’ya (Polina) Yakovlevna Tugarina (1928–2004) was a Russian ichthyologist as well as being a ‘renowned’ researcher of the graylings of Siberia and Russia’s Far East, especially in the Lake Baikal Region. [...] (Ref. 128868), visit book page.

脊椎骨: 49 - 55. The species is characterized by the following: Pored lateral line scales 75-91; unbranched rays in first dorsal fin 8-12, in second dorsal fin 13-17, total dorsal fin rays 23-26; number of vertebrae excluding urostyle 49-55; pyloric caeca 11-20; a wide red to maroon edging with the width 5-6 mm is seen along the upper margin of the dorsal fin, broadening towards the posterior end of the fin (in large males it may be 10 mm in width or more); below it , parallel with the edging, there are 4-5 rows (bands) of same-color spots; the upper row is slightly separated
from the edging and the bands below, and consists of the largest, slightly horizontally elongated oval spots; the lowest row of the spots, adjoined to the fin base, is weakly pronounced; bright orange sinuous stripes between the scale rows going along the body.; upper jaw overlaps with the anterior margin of the eye; length of dorsal fin base is from 25.3 to 33.3% SL; body significantly compressed laterally, its average depth is 22.9% SL; no teeth on vomer (Ref. 57969).
Body shape (shape guide): fusiform / normal.
此魚種特徵為那在:之後 有細孔的側線鱗片 75-91; 在第一背鰭 8-12 中的不分枝的鰭條, 在第二背鰭鰭 13-17, 總背鰭鰭條 23-26; 排除尾桿骨 49-55 的脊椎骨的數字; 幽門的盲腸 11-20; 一個寬的紅色到褐紅色的邊緣用寬度 5-6 mm 被見到沿著背鰭的上緣, 擴大向鰭的後端;(在大的雄性中它寬度可能是 10 mm 或更多) 下面它 , 與邊緣平行, 有相同-彩色斑點的 4-5 列 (條紋); 上面的列些微地被分開
從邊緣與條紋在下面, 而且由最大的組成, 些微地水平地延長橢圓形斑點; 斑點的最低列, 鄰接了到鰭的基底, 微弱明顯; 在去的鱗片列之間的鮮橘色的彎曲斑紋沿著身體。; 上頜與眼的前緣部分重疊; 背鰭長基底是從 25.3 對 33.3% SL; 身體重要地扁長形的側面地，它的平均深度是 22.9% SL; 沒有牙齒在犛骨.(參考文獻 57969)
The species spawns in rivers of the Amur Basin from the middle to the end of May, 7-10 days
before the T. grubei flavomaculatus. The autumn downstream migration in tributaries of
the lower Amur takes place from September to October. The range of the food components of the Lower Amur grayling in the Anyui River in July is represented by various zoobenthos organisms. The most weight part in the food boluses of fish older than the age 3+ is
represented by mayfly and stonefly larvae, imago caddis and bugs. The composition and the frequency of occurrence of different organisms in the food boluses of the Lower Amur grayling. Comparison of the feeding spectra in the Lower Amur and yellow-spotted graylings caught in the same stations did not reveal any significant differences in the diversity of the food components (Ref. 57969).
此魚種在阿穆爾河流域從中央到五月底的河中產卵, 7-10 天
