檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 7; 背的軟條 (總數) : 13 - 14; 臀棘: 1; 臀鰭軟條: 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 有分段背鰭棘條與臀鰭棘條的圓形鱗片與相當高數量。
Found on sand and rubble with small patches of mostly dead coral or at the base of a drop-off.
棲息於沙子了，而且碎石有小的大部份死珊瑚的區塊或在急下降的基底。
