Etymology: Bedotia: After Maurice Bedot, 1859-1927; born in Geneva, systematist on Hydrozoan; alveyi: This species is named in honour of Dr. Mark Alvey (FMNH) in recognition of his tremendous efforts to promote natural history research and species discovery during his tenure as Administrative Director of Academic Affairs (Ref. 84245).

Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 16 - 25; Duri dubur: 0; Sirip dubur lunak: 17 - 22; vertebrata, bertulang belakang: 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).
