توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 16-25; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 17 - 22; مهره ها: 35 - 37. Diagnosis: A species of Bedotia that uniquely possesses a distinctive crescent-shaped to semi-circular spangle on the posterior half of many opercular and flank scales, forming golden, occasionally whitish to bluish, iridescent highlights (Ref. 84245). Bedotia alveyi is further distinguished from congeners by a single diffuse broad midlateral band, vs. two distinct bands in B. geayi and B. madagascariensis, and absence of bands in B. masoala and B. marojejy; sparse and irregular lateral blotching between scales when alive, vs. extensive spots and/or blotches present in life and preservation in B. leucopteron, B. marojejy, and B. masoala; the absence of broad white margins on the second dorsal and anal fins, vs. white margins in B. albomarginata; and rust-red caudal-fin lobes, vs. hyaline to orange in B. longianalis and broadly outlined in black in B. tricolor (Ref. 84245).
Tributaries harbouring this species are generally shallow, clear, and cool, with a moderate rate of flow, and low turbidity; the substrate ranges from rocky (small rock to large boulders) to somewhat sandy (Ref. 84245).
