背的软条 (总数) : 7 - 8; 臀鳍软条: 9 - 10; 脊椎骨: 35 - 36. Can be differentiated from Pseudecheneis paviei in possessing 14-20 transverse ridges (laminae) of thoracic apparatus (vs. 9-13); from Pseudecheneis paviei and Pseudecheneis sulcatoides in having furcated neural spine of complex vertebra (vs. single); from P. immaculatus, P. tchangi, and P. paucipunctatus in having yellow spots and patches at occipital, post-temporal, origin and base end of the dorsal fin and adipose fin, and caudal fin base (vs. absent or lacking); from Pseudecheneis gracilis and Pseudecheneis stenura in having a shorter caudal peduncle (19.9-30.0% SL vs. 26.0-35.8); from Pseudecheneis sulcata in having a longer pelvic fin, reaching base of first anal fin ray (vs. not reaching); and from Pseudecheneis crassicuada in having a longer pectoral fin, reaching origin of pelvic fin (vs. not reaching); and 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%); and from Pseudecheneis sympelvica in having separate pelvic fins (vs. fused) (Ref. 74729).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00260 - 0.01333), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
