Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 7 - 8; Raggi anali molli: 9 - 10; Vertebre: 31 - 32. Distinguished by the following autapomorphy: very large lateral process on base of fifth median anal-fin radial of adult males. Differs from Phallotorynus jucundus by having 7 or 8 dorsal-fin rays (vs. 9 or 10) and from P. fasciolatus by its color pattern with one spot (vs. spotless); from P. pankalos by its color pattern comprising of one spot (vs. six to nine spots). Differs from P. jucundus and P. victoriae by having 13 epipleural ribs (vs. 11 or 12); and differs further from P. victoriae by having 9 gonopodial rays vs. 8 (Ref. 56059).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00454 - 0.02306), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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