🔬 Taxonomy

🐟 Physical Description

Dorsal soft rays (total): 27 - 29; Anal soft rays: 17 - 19; Vertebrae: 32 - 34. This species is distinguished by the following characters: differs from P. paucus by having greater number of dorsal-fin rays (27-29 vs. 24-25), anal-fin rays (17-19 vs. 15-16), pectoral-fin rays (17-20 vs. 16-17), and vertebrae (32-34 vs. 31); from P. andriashevi by having fewer dorsal-fin rays (27-29 vs. 31-37), anal-fin rays (17-19 vs. 19-22), and vertebrae (32-34 vs. 36-39); and from both species by caudal-fin morphology (ventral caudal spur absent, procurrent rays cylindrical vs. ventral caudal spur present, procurrent rays flattened, bladelike); differs from P. rhyton and P. mauli by morphometrics, including a deeper body (52-64% vs. 45-52% SL), longer head length (>38% vs. 39% vs.
