背的软条 (总数) : 6 - 7; 臀鳍软条: 8 - 9; 脊椎骨: 31. This species is distinguished from its congeners and all species of other genera of the subfamily Rivulinae by the following characters: pelvic-fin rays 4 in females, 5 in males(vs. 5-7 in both sexes of other congeners, 6-9 in other rivulines), branchiostegal rays 4 (vs. 5-6); anterior portion of anal fin, involving the space occupied by the first two fin rays, white in both sexes; differs from all its congeners, except L. uatuman, by having the caudal fin dark coloured in males (dark crimson red in L. jauaperi, dark grey in L. uatuman) with a contrasting distal white band (vs. caudal fin never dark coloured, distal white band absent); further differs from
L. uatuman by having caudal fin dark crimson red in both sexes (vs. dark grey in males, hyaline in females) and with five pelvic-fin rays in male and four in female (vs. six in both sexes) (Ref. 95090).
