Etymology: Acentrophryne: Greek, 'a' = without + Greek, 'kentron' = prickle or spine + Greek, 'phryne' = toad (highlighting the single most important distinguishing feature of this genus: the absence of a preopercular spine) (Ref. 86949); dolichonema: Name from the Greek word 'dolichos', meaning long; 'nema' meaning filament or thread, in allusion to the long, filamentous , distal escal appendage of this species.

Rayons mous dorsaux (Total) : 3; Rayons mous anaux: 3. Diagnosis: Metamorphosed females of Acentrophryne dolichonema differs from A. longidens in having a much longer distal escal appendage (27.6-35.7% SL vs. 2.3-2.5% SL ); a longer illicium (63.6-70.5% SL vs. 35.7-54.9% SL); a narrower head (25-28.1% SL vs. 35.7-37.3% SL); and a fewer number of pectoral fin rays (16 vs. 18-19) (Ref. 54827); caudal fin rays 9, ninth ray (ventral most) 10.5-17.3% SL (Ref. 86949).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
