Thiis species, together with L. citrauratea and L. micra, is distinguished from all other congeners by the presence (vs. absence) of a row of orange dots or an orange stripe extending along the dorsal mid-line of the body from the nape to the caudal-fin base; it differs from citrauratea and micra with the caudal fin emarginate (vs. forked) and in having two rounded (vs. broadly pointed) lobes, shorter head 18.4-22.8% SL (vs. 22.5-26.8% SL in citrauratea and 23.6-25.9% SL in micra), slender caudal peduncle (14.6-20.0% SL (vs. 12.1-15.8% SL in citrauratea and 11.8-13.5% SL in micra), shorter dorsal fin 9.0-11.6% SL (vs. 13.7-18% SL in citrauratea and 11.0-4.6% SL in micra), and shorter anal fin 8.1-11.4% SL (vs. 13.0-17.7% SL in citrauratea and 15.3-16.8% SL in micra) (Ref. 123772).
Cross section: oval.
Collected in fast-flowing clear water with mixed substrate including pebbles, gravels and boulders. Syntopic species included Sarcocheilichthys parvus, Acrossocheilus wenchowensis, Cobitis sinensis, and Rhinogobius giurinus (Ref. 123772).
