Teleostei (teleosts) > Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Cichlinae
Etymology: Isthmoheros: Name from combination of ‘ isthmos’ meaning narrow passage or neck of land, with the old cichlid genus name Heros (meaning hero); referring to the isthmian hero, as it is the only eastern Isthmian genus that has its sister-genus on the opposite side of the Isthmus in western Panamá-Costa Rica..

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00706 - 0.03245), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
