Dorsale stekels (totaal) : 16 - 18; Dorsale zachte stralen (totaal) : 11 - 12; Anale stekels: 3; Anale zachte stralen: 7 - 9; Wervels: 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.
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).
