Abstract

Recently collected specimens of Australoheros mattosi in water courses around locality type (Das Velhas River drainage, including Upper Cipó River, Minas Gerais, Brazil) revealed new data on the adult live coloration (iridescent markings on the base of the dorsal and anal fins and reddish to grayish hyaline coloration on the distal margin of the caudal-fin), population (dorsal head profile and head ground coloration) and ontogenetic variations (variation in the nostril position, head ventral profile, scales on the cheek and the anal and dorsal fins, spot on the posterior margin of the operculum, and ground coloration in alcohol) on the external morphology and new morphometric data (pelvic-pectoral distance, eye position in relation to the horizontal axis at the symphysis and the 5th ceratobranchial levels) on adult individuals.
