Etymology: Leporinus: Latin, lepus, leporis = rabbit (Ref. 45335); arimaspi: Named after the mythical Arimaspi people of northern Scythia in Greek mythology. The large black spot on the midlateral portion of the body in this new species is reminiscent of the single, pronounced, centrally located eye that the Arimaspi people were said to possess. A noun in apposition..

简单描述
型态特徵 | 形态测量图
背的软条 (总数): 12; 臀鳍软条: 10; 脊椎骨: 38. Leporinus arimaspi is distinguished from all other congeners except L. aripuanaensis, L. amazonicus, L. apollo, L. cylindriformis, L. niceforoi, and L. ortomaculatus by the combination of an extremely dorsoventrally slender body (body depth immediately anterior to the dorsal-fin origin of 19-27% SL, versus 29% SL or greater) and the pigmentation pattern consisting of one or more dark spots centered along the lateral-line scale row. It differs from L. apollo, L. cylindriformis, L. niceforoi, and L. ortomaculatus by the lack of the dark spot along the lateral-line posterior to the dorsal-fin insertion and anterior to the adipose-fin origin (vs. presence of an intense dark spot). It further differs from L. apollo and L. cylindriformis by having five upper transverse scale rows (vs. six in most specimens), and four lower transverse scale rows (vs. five in most specimens), and from L. ortomaculatus by the absence of rows of spots dorsal and ventral to the lateral-line scale row (vs. presence); from L. amazonicus by having 37- 40 total scales on lateral line (vs. 43–45), 38 vertebrae (vs. 41), and four lower transverse scale rows at the pelvic-fin insertion (vs. 5 in most specimens). It is readily distinguished from the most similar species, L. aripuanaensis, by the absence (or faint presence) of a circular dark spot over the hypural plate (vs. presence of an intensely pigmented dark spot in that position). It can be further diagnosed from L. aripuanaensis by having 12 modal predorsal scales (vs. 11), as well as the following morphometrics in specimens between 7.0 and 9.2 cm SL: interorbital width 34-44% HL (vs. 29-34% HL) and eye diameter 29-34% HL (vs. 25-30% HL) (Ref. 96504).
Found in rivers. Some specimens were collected near bedrock outcroppings and banks (Ref. 96504).
