Issue
Originally decribed as a subspecies of P. cameronensis, P. abbreviata is questionably distinct, and more reliable diagnostic characters are needed to verify its status (Ref. 81636).

背棘 (总数) : 0; 背的软条 (总数) : 9 - 11; 臀棘: 0; 臀鳍软条: 8 - 9; 脊椎骨: 37 - 38. Diagnosis: body depth 6.65-7.2 times in SL (Ref. 89136), 11.9-15.5% SL, with greatest depth at or slightly anterior to dorsal fin (Ref. 81636). Head length 4.1-4.8 times in SL (Ref. 89134, 89136), 17.9-22.7% SL (Ref. 81636). Snout length 2.65-3 times in HL (Ref. 89136). Eye dorsolateral (Ref. 81636, 89136), 3.85-4.8 times in HL, 1.4-1.8 times in snout length (Ref. 89134, 89136), 1.1-1.5 times in interorbital distance (Ref. 89136). Interorbital distance wide, 27.8-43.4% HL (Ref. 81636). Dorsal fin origin 1.15-1.2 times further from snout tip than from caudal fin origin; anal fin origin 1.85-2.15 times further from pelvic fin origin than from caudal fin origin (Ref. 89136). Pectoral fin enlarged and paddle-shaped (Ref. 81636), 4.5-5.1 times in SL (Ref. 89134, 89136), 0.9-0.95 times longer than head (Ref. 89136). Pelvic fin 6.2-7 times in SL, 1.35-1.5 times in HL (Ref. 89136). Both pectoral and pelvic fins fan out from body in the horizontal plane formed by the ventral surface (Ref. 81636). Caudal peduncle 1.4-1.7 times longer than deep (Ref. 89134, 89136).
Body shape (shape guide): elongated; Cross section: oval.
