According to Kottelat & Lim 1992, L. hasselti is distinguished from other described species of Lepidocephalichthys in Southeast Asia in usually having an ocellated black spot centered at base of branched caudal rays 3-4; or it replaced by black or darker area. Its size is up to 45 mm SL; body with a median longitudinal stripe or a row of adjacent black spots, with an unpigmented stripe above it, back marmorated, finely spotted or blotched. Caudal fin with series (usually 3-6) of vertical bars; dorsal origin above posterior extremity of pelvic base.[5]
