This species shares with L. micra and L. brachycephala the unique presence of a row of orange spots or an orange stripe along the dorsal mid-line of the body, extending from the nape to the caudal-fin base; differs from the two by its caudal fin deeply forked (vs. emarginate), the length of median rays 1.7-2.3 times in length of upper lobe (vs. 1.3-1.4 in micra, 1.2-1.5 in brachycephala), the pelvic fin inserted slightly posterior or inferior (vs. slightly anterior in brachycephala) to the dorsal-fin origin, a longer head, 22.5-26.8% SL (vs. 18.4-22.8% SL brachycephala) and a shorter predorsal distance 51.4-56.3% SL (vs. 58.1-59% SL in micra) (Ref. 123772)..
