Maturity: Lm ? range ? - ? cm
Max length : 14.1 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4996)
背棘 (总数) : 16 - 18; 背的软条 (总数) : 11 - 12; 臀棘: 3; 臀鳍软条: 7 - 9; 脊椎骨: 33. P. pleurotaenia is relatively small, attaining about 115 mm SL. Differs from P. kirkii, P. labridens, P. similis, P. marginatus, and P. spilonotus in the small mouth which is less than 33% of the head length. Like P. kirkii and P. labridens it has some enlarged pharyngeal teeth. Caudal fin emarginate.
P. pleurotaenia 是相当小的, 达到大约 115 mm SL 。 有别于在小的嘴中 P. kirkii ， P. labridens ， P. similis ， P. marginatus 与 P. spilonotus 是少于 33% 的头长。 例如 P. kirkii ，而且 P. labridens 它有一些增大的咽齿。 尾鳍边缘微凹的。
Found in vegetated areas between rocks and sand. Feeds on invertebrates that it locates in the sand by blowing into the upper sediment layer (Ref. 5595).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.5 ±0.37 se; based on food items.
回复力 (Ref.
