Morphology | Morphometrics
soft rays: 8. Differs from all other Japanese striated spined loaches by having the following characters: prepelvic myotome number commonly 13; body color pattern consisting of 5 longitudinal lines of pigmentation (abbreviated as lines L1 to L5) (line L3 formed by sharp longitudinal line, reaching to caudal base; line L4 formed by narrow longitudinal line, reaching beyond dorsal fin, narrower than L3 in male of non-spawning season; line L5 organized in 11-14 roundish, oblong or ovoid blotches in non-spawning season); caudal fin and dorsal fin with 3-4 arcuate bars; upper spot at the caudal base jet-black comparable in size to eye diameter; lower spot at caudal base faint or missing; lamina circularis at the base of the pectoral fin of adult male simple roundish plate, the upper segments of the first branched soft ray narrow and weak; egg yolk diameter approximately 1.0 mm; and karyotype diploid (Ref. 92393).
Oviparous, with distinct pairing during breeding (Ref. 205).
