Duri punggung (Keseluruhan (total)) : 1; duri punggung lunak (Keseluruhan (total)) : 7; Sirip dubur lunak: 6; vertebrata, bertulang belakang: 26. This species is distinguished from all congeners except H. spectabile, by the pattern of abdominal plates, consisting of a pair of slender plates posterior to the coracoids followed by a series of 1-3 unpaired medial abdominal plates (vs. 2 or 3 series of abdominal plates); by having the posterior process of the coracoid strongly curved, its distal tip pointing dorsally (vs. posterior process smoothly curved and distal tip pointing posterodorsally); and by the absence of basipterygium fenestrae (vs. with basipterygium fenestrae). This species is distinguished from H. spectabile by the presence of thoracic plates; greater number of total lateral plates 21-22 (21) (vs. 20-22 (20)); greater number of dentary teeth, 21-37 (30) (vs. 20-31 (24)); greater dorsal interorbital distance with mean dorsal interorbital distance 63.5 (vs. 58.5); pelvic fin placed more posteriorly, mean pectoral-pelvic distance 15.5 (vs. 12.7); and longer pectoral fin, length reaching or surpassing the anal-fin origin, the mean pectoral-fin spine length 39.3 (vs. 29.8) (Ref. 84367).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.4 ±0.1 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
