Dorsal spines (total): 4-4; Dorsal soft rays (total): 6-6; Anal spines: 4-4; Anal soft rays: 5-5; Vertebrae: 36-40. This species is distinguished from its congeners by the following characters: with a narrow conspicuous dark brown band between the base of outer rostral barbel and eye (vs. absence, or light and/or indistinct if present) and eyes located dorsally on the head (vs. dorsolaterally); differs from L. costata, L. pleskei, L. nikkonis, and L. sayu by absence of a rhomboid or triangular dark blotch on the middle of the caudal-fin base (vs. presence); differs from L. echigonia by absence of dark spots on the dorsal and caudal fins, or sparse if present (vs. presence) (Ref. 128930). |
| Occurs at the uppermost reaches of mountain streams surrounded by dense natural vegetation; preferring sandy bottoms with gravel or pebbles, where it hides under rocks and stones. It is syntopically distributed together with L. echigonia in the Yura and Kako rivers, although L. echigonia has a tendency to inhabit more lentic waters in swampy streams and ditches (Ref. 128930). |
