Remark: Redescription, as <i>Heros appendiculatus</i>, in Kullander (1986: 219), based on Peruvian material, with bibliography, diagnosis, description, distribution and illustration. Oldest available name now applied. Status of the included nominal species needs further analysis.
Comments: Has been caught, sporadically, in lentic environment such as zones of flooded grounds, as well as estuaries where the tidal current is notable, along the banks with thick riverine vegetation.  Omnivorous but mainly frugivorous (Ref. 35237).
