简单描述 型态特徵 | 形态测量图

背棘 (总数): 2; 背的软条 (总数): 6-7; 臀棘 0; 臀鳍软条: 10 - 12; 脊椎骨: 35 - 37. Body compressed (Ref. 52369). Predorsal profile steep; postdorsal body sloping gently ventrally (Ref. 52369). Head depressed and broad, broadly rounded when viewed laterally and with rounded snout margin when viewed from above (Ref. 52369). Eye large and ovoid, horizontal axis longest (Ref. 52369). Mouth inferior and crescent-shaped; lips plicate (Ref. 52369). Barbels in three pairs; maxillary barbel long and slender, extending to just beyond base of last pectoral-fin ray; inner mandibular-barbel origin close to midline, extending to base of pectoral spine and with 2 short, thin branches on anterior half and 3-4 long, thin branches on posterior half; outer mandibular barbel originates posterolateral of inner mandibular barbel, extending to middle of pectoral-fin base and with 3-4 long, thin branches (Ref. 52369). (Ref. 52369). Gill openings narrow, extending from immediately ventral to posttemporal to immediately ventral to base of pectoral spine (Ref. 52369). Dorsal fin located at anterior third of body, with convex margin; dorsal-fin spine long, stout and slightly curved, smooth on both anterior and posterior margins (Ref. 52369). Adipose fin moderately long; margin slightly convex for entire length and posterior end deeply incised (Ref. 52369). Caudal fin rounded, with i,5-6,6,i principal rays (Ref. 52369). Anal-fin base located ventral to posterior half of adipose fin, with iii-iv,7-8 rays and convex margin (Ref. 52369). Pelvic-fin origin at vertical ventral to posterior end of dorsal-fin base, with slightly convex margin (Ref. 52369). Pectoral-fin spine slightly curved and stout; anterior spine margin with 3-16 small serrations along entire length of spine, serrations antrorse on distal two-thirds and anteriorly directed on proximal third; posterior spine margin with 6-12 strong serrations along entire length (Ref. 52369). Lateral line complete and midlateral (Ref. 52369). 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 (Ref. 52369). Snout with a series of cream spots delineating anterior and posterior nares; cheek region with one or two cream spots immediately ventral to orbit; cream band encircling nape at supraoccipital (Ref. 52369). Dorsal third of body with series of five cream vertical bar-shaped marks extending to lateral midline of body: first at middle of dorsal-fin base, second at adipose-fin origin, third at middle of adipose-fin base, fourth at posteriormost point of adipose-fin base and last on caudal peduncle immediately posterior to adipose fin (Ref. 52369). Ventral third of flanks with a longitudinal series of four to seven cream spots or vertical bar-shaped marks (Ref. 52369). Adipose fin brown, with an extensive hyaline margin; dorsal, pectoral, pelvic and anal fins hyaline with one to two rows of elongate spots forming longitudinal brown rows; caudal fin hyaline, with elongate brown spots forming two to three irregular columns (Ref. 52369)
