Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 11; Afterflossenweichstrahlen: 33 - 35; Wirbelzahl: 38 - 39. Distinguished from all species of Acestrocephalusexcept Acestrocephalus boehlkei and Acestrocephalus maculosus by having a dark humeral blotch. Differs from Acestrocephalus boehlkei in having fewer anal-fin rays 29-31 (vs. 34-36) and fewer scale rows around caudal peduncle 22-23 (vs. 25); and from Acestrocephalus maculosus in having more anal-fin rays 29-31 (vs. 25-27). The muscular hiatus of the pseudotympanum in Acestrocephalus stigmatus is narrower than that of Acestrocephalus boehlkei, but much more developed than that of Acestrocephalus maculosus (Ref. 75890).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00449 - 0.01852), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
