Etymology: Pseudecheneis: Greek, pseudes = false + Greek, echein = to hold + Greek, nays = ship; remora, suckling fish; 1774 (Ref. 45335); longipectoralis: Derived from the Latin adjectives long (long) and pectoralis (pectoral fin), in reference to pectoral fin longer and extending to pelvic fin base..

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 7 - 8; Afterflossenweichstrahlen: 10 - 11; Wirbelzahl: 35. Differs from Pseudecheneis sulcata in possessing longer pelvic fin, reaching base of first anal fin ray (vs. not reaching); and from Pseudecheneis crassicauda in having longer pectoral fin, reaching origin of pelvic fin (vs. not reaching); from Pseudecheneis serracula in having shorter adipose fin base (length of adipose fin base 125-166.7% in length of anal fin base vs. larger than 200%); and from Pseudecheneis sympelvica in having separate pelvic fins (vs. fused). Can be differentiated from other congeners except Pseudecheneis immaculatus in having longer pectoral fin (28.7-38.1% SL vs. 24.5-35.9), extending to pelvic fin (vs. not extending); and differs from P. immaculatus in having yellow spots or patches on the body (vs. lacking ) (Ref. 74729).
