简单描述 型态特徵 | 形态测量图

脊椎骨: 35 - 36. Differs from members of the genus by the following combination of characters: absence of dark stripes on body; absence of bold concentric bands on posterior part of paired fins; pelvic fin not reaching anal-fin origin; general appearance robust, body width at dorsal-fin origin 24.2-28.0% SL; caudal peduncle depth 10.7-11.2% SL; caudal peduncle length 0.8-0.9 times in its depth; predorsal body length 51.3-53.7% SL; pelvic-fin origin in front of dorsal-fin origin; absence of cavity around mouth; skin-fold between oropectoral membrane and ventral surface of head running from pectoral-fin origin to second rostral barbel; tubercles on dorsal part of head concentrated on lateral part of snout; absence of large tubercles on branched pectoral-fin rays 15-21; and 60-70 lateral line scales (Ref. 40433).
在它的比较微暗颜色,较大中有别于亚属 Sewellia 的成员, 在雄性中的比较不明显胸鳍 tuberculation, 腹鳍失败在后部地延伸到臀鳍起源 , 与更多的脊椎骨.(35-36 对 31-34) Pectoral fin rays i23-26 ,腹鳍鳍条 i 18-20. 从 S. elongata Diardichthys 的唯一的其他成员,它在身体上不同之处为它的更加结实的身体,较深的尾柄 , 彩色标志通常更细分开 (没有例外在方式系列), 与通常较少的脊椎骨。
