简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 7; 背的软条 (总数) : 13 - 14; 臀棘: 1; 臀鳍软条: 12 - 13; 脊椎骨: 26. This species is distinguished by the following set of characters: D VI + I,13 (rarely I,14); anterior rim of posterior nostril raised, without well-developed flap; mainly cycloid on body; head and body pale, with reticulate mottling dorsally (Ref. 115539).
非常近似 X. chapmani 有分段背鳍棘条与臀鳍棘条的圆形鳞片与相当高数量。
Found on sand and rubble with small patches of mostly dead coral or at the base of a drop-off.
栖息于沙子了，而且碎石有小的大部份死珊瑚的区块或在急下降的基底。
