Etymology: Lepidocephalichthys: Greek, lepas = limpet + Greek, ichtys = fish (Ref. 45335); alkaia: Alkaia is Greek for "lion’s tail", in reference to the tail-like dark stripe on the caudal fin (Ref. 83671).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 26°N - 16°N, 97°E - 98°E
Lepidocephalichthys alkaia is known from four collections from Myanmar. The holotype and paratypes are from the Nan Kwe River, Irrawaddy drainage, Kachin Province. Other specimens are from the Salween drainage, Kayin Province. Habitats where these collections were made include streams and oxbow lakes. Some collections included L. goalparensis, which is often associated with slow flowing-streams and dense vegetation (Ref. 83671).

Morphology | Morphometrics
Lepidocephalichthys alkaia is distinguished from all other Lepidocephalichthys by a midlateral dark stripe on caudal fin, extending from base to terminus of fin, usually spanning rays 7–10. It is further distinguished from all Lepidocephalichthys by the combination of a truncated or rounded caudal fin; scales absent on top of head; usually dark stripe, sometimes dark spots on side; dorsal-fin origin just posterior to pelvic-fin origin; 8–10 predorsal, 8–10 postdorsal, dark bars on dorsum; moderate size (to 38 mm SL) (Ref. 83671).
