Könsmognad: Lm ?  range ? - ? cm
Max length : 10.9 cm SL hane/ej könsbestämd; (Ref. 43281)
Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 7 - 8. Black semicircular mark on each caudal lobe (Ref. 43281). Can be distinguished from its congeners by having a small scaleless midventral region only restricted to chest. Differs from P. robustus in having slightly crenulated rostral fold with 12-15 indentations on its distal margin, a shallower caudal peduncle (depth 63.7-71.3% of its length) and a larger mental adhesive disc (length 72.7-80.7% of its width) (Ref. 49783). Also Ref. 75600.
Body shape (shape guide): elongated.
