Coloration: dorsal and lateral surfaces of head and body light to medium brown, fading to cream on belly and ventral surfaces in preserved specimens; dorsal and lateral surfaces of head and body frequently with dark brown elongate spots evenly distributed and forming a reticulate pattern; snout with a series of cream spots delineating anterior and posterior nares; cheek region with 1-2 cream spots immediately ventral to orbit; cream band encircling nape at supraoccipital (Ref. 52369). Dorsal third of body with series of 4 (Ref. 81251) or 5 (Ref. 52369) cream vertical bar-shaped marks extending to lateral midline of body: 1st at middle of dorsal-fin base, 2nd at adipose-fin origin, 3rd at middle of adipose-fin base, 4th at posteriormost point of adipose-fin base (Ref. 52369, 81251) and last on caudal peduncle immediately posterior to adipose fin (Ref. 52369). Ventral third of flanks with a longitudinal series of 4-7 cream spots or vertical bar-shaped marks; adipose fin brown, with an extensive hyaline margin; dorsal, pectoral, pelvic and anal fins hyaline with 1-2 rows of elongate spots forming longitudinal brown rows; caudal fin hyaline, with elongate brown spots forming 2-3 irregular columns (Ref. 52369, 81251).
