Новый род Южно-американских цихлид.
Пока к нему отнесены 3 вида:
Australoheros facetus (Jenyns, 1842)
Australoheros tembe (Casciotta et al., 1995)
Australoheros scitulus (Rican & Kullander, 2003)
Общее число видов может достигнуть в ближайшее время семи.
Типовым видом является Australoheros facetus (Jenyns, 1842), бывшая "Cichlasoma" facetum. Остальные два вида также относились к ‘Cichlasoma’-facetum группе.
Character- and tree-based delimitation of species in the 'Cichlasoma’ facetum group (Teleostei, Cichlidae) with the description of a new genus.Аbstract:
The ‘Cichlasoma’ facetum group is part of the taxonomically complex group of Neotropical cichlid fishes of the tribe Heroini. Many species groups and unplaced species of heroines are still left without a generic name following the revision of the genus Cichlasoma.
We describe here the ‘Cichlasoma’ facetum group as a new genus, Australoheros, and provide evidence for its monophyly based on phylogenetic analyses of morphological and mtDNA characters. Australoheros is morphologically characterized by the lowest values in meristic characters among heroines and by three apomorphic characters in coloration pattern. In addition to the three described species of Australoheros, our results of species delimitation based on a combination of tree- and character-based approaches identify seven putatively new species of Australoheros.
Several coding schemes of morphological characters are used to recover the intrageneric relationships within the genus, resulting in very similar topologies. Discovery of additional species within the genus is expected once material from the whole distribution area is studied.
