Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 6; Mjukstrålar i ryggfenan (totalt) : 9; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 20 - 23. This species is distinguished by having a midventral, black, pin-like mark, about half length of pelvic fins, within a white band that encircles head of pin just anterior to anus (not present in juveniles); pectoral-fin length 3.3-3.45 in SL; preanal length 1.45-1.55 in SL; dorsal profiles of head and nape are nearly straight; iris in alcohol silvery white; differs from P. guentheri in having smaller eye size (40-50 mm in SL vs. 7.6-7.7 mm in SL in P. guentheri (Ref. 107896).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
