背鰭 (合計) : 8; 臀鰭: 10; 脊つい: 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). Can be differentiated further from Pseudecheneis serracula in having a shorter adipose fin base (length of adipose fin base 125-166.7% in length of anal fin base vs. larger than 200%), from Pseudecheneis sympelvica in having separate pelvic fins (vs. fused), from Pseudecheneis paviei in having 14-18 transverse ridges (laminae) of thoracic apparatus (vs. 9-13), further from Pseudecheneis paviei and Pseudecheneis sulcatoides in having a furcated neural spine of complex vertebra (vs. single), from Pseudecheneis immaculatus in having yellow spots and patches on some parts of the body except occipital and posttemporal (vs. absent), from Pseudecheneis tchangi and Pseudecheneis brachyurus in lacking yellow spots and patches on occipital and posttemporal (vs. presence), from Pseudecheneis longipectoralis in having shorter pectoral fin, not extending to base of pelvic fin (vs. extending), and from Pseudecheneis gracilis and Pseudecheneis stenura in having a shorter caudal peduncle (23.9-29.3% SL vs. 26.0-35.8) (Ref. 74729).
Body shape (shape guide): elongated.
