Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 11; Épines anales: 0; Rayons mous anaux: 20 - 22; Vertèbres: 33 - 35. Diagnosis: Distinguished from its congeners except L. insularis, L. lankensis, L. ruhuna, and L. varuna by its colour pattern, including a dark stripe along the middle of the posterior third of the side or slightly shorter, anteriorly replaced by 6–11 short vertical bars (vs. presence of a dark stripe along the side but no bars in L. fasciata, L. parafasciata, and L. trevori; plain sides or presence of a very narrow posterior stripe in L. khujairokensis, L. latens, and L. laubuca; indistinct vertical bars anteriorly on the side, followed by a dark stripe ending in a triangular spot on the caudal-fin base in L. siamensis; a few dark bars present anteriorly on the side but lateral band absent in L. caeruleostigmata); distinguished from L. fasciata, L. latens and L. trevori also by more dorsal-fin rays (ii.8½ vs. ii.7½) and from L. siamensis by the absence of a dark spot on the caudal-fin base; distinguished from L. insularis by fewer scales in the lateral line (29–32 vs. 34–36), shorter pelvic fin (not reaching to vent, vs. reaching to bases of anal-fin rays 3–8); from L. lankensis by fewer scales in the lateral line (29–32 vs. 34–37); from L. ruhuna and L. varuna by the presence of an entire, narrow lateral band on the posterior third of the body, vs. a series of blotches along the side which may form a broad band extending anteriorly to about the middle of the side (Ref. 118870).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
