背棘 (总数) : 15 - 16; 背的软条 (总数) : 10 - 11; 臀棘: 3; 臀鳍软条: 9 - 10; 脊椎骨: 31. Distinguished from P. taeniolatus by the more strongly marked pattern of longitudinal and vertical black stripes and in having fewer and larger teeth in the outer row of the upper jaw and on the lower pharyngeal bone, in having more fleshy lips which partly obscure the posterior teeth of the upper jaw, and in having fewer gill rakers, with the anterior ones very low and blunt. Differs from P. virgatus in not having the posterior teeth of the two inner rows of the lower pharyngeal enlarged.
更强烈与 P. taeniolatus 区分藉由标示了纵向而垂直黑色的斑纹图案而且在上颌的外部列中与在下面的咽骨上有较少与较大的齿, 有更多的肉质部分使上颌的后面的齿阴暗, 而且有较少的鳃耙的唇, 藉由前面的一些非常低而钝的。 有别于 P. virgatus 在没有两者的后面齿内部的列下面的咽增大。
Inhabits rocky shores and adjacent sandy areas. Characteristic of areas where the rocks are covered with a sediment layer. Feeds by blowing sediment off the rocks and picking at food items remaining (Ref. 267).
栖息于岩岸与毗连的沙地。 岩石被覆盖着沉淀物层的区域的特性。 吃藉由把沉淀物吹走岩石而且啄食保持的食物组成.(参考文献 267)
