Morfologie | Morfometrie
Dorsale stekels (totaal): 7; Dorsale zachte stralen (totaal): 9-10; Anale zachte stralen: 8 - 9; Wervels: 26. This species is distinguished by the following set of characters: D VI+I,9-10 (usually 9), with second dorsal-fin spine forming an elongate filament extending to between base of fourth and last segmented dorsal-fin ray when adpressed; A I,8–9 (usually 9); pectoral-fin rays 18; relatively broad interorbital (75-91% pupil diameter); 10-12 papillae in posterior transverse interorbital row; the upper part of opercle with about 10-12 scales arranged in 3 or 4 transverse rows; pelvic without frenum. Colour when fresh is generally yellow (including iris, except opercle, upper part of cheek, and area
immediately behind eye sometimes pinkish); head, body, and fins covered with numerous pepper-like melanophores, most prominent on side of body; fins yellow, except pelvic fins translucent; second dorsal fin, caudal fin, and anal fin with blue margin, widest on anal fin; dorsal fins with narrow blue stripe at base, second dorsal fin also with longitudinal row of blue spots just above stripe; filamentous extension of second dorsal-fin spine blue (Ref. 118649).
Specimens were collected using rotenone in a sheltered bay on a mainly flat mud bottom in 30 m depth. Seldom collected due to its small size and predilection for seldom-dived, mud-bottom habitat. It is likely to live in the burrows of larger mud-dwelling fishes such as jawfish or Oxymetopon ribbongobies (for P. aithiops found at the type locality also shelters in the burrows of Oxymetopon compressus) (Ref. 118649).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.

Weerstandsvermogen (Ref.
