Australoheros angiru sp.nov.

Australoheros angiru
Australoheros angiru (from publication)

new species from Argentina:
Australoheros angiru Rícan, Piálek, Almirón & Casciotta, 2011

distribution (from publication):
Australoheros angiru has a disjunct distribution in the rio Iguaçu and in the upper rio Uruguai. One locality is so far known from the middle río Uruguay in Misiones province, Argentina.

published in:
Rícan, O., L. Piálek, A. Almirón & J. Casciotta (2011):
Two new species of Australoheros (Teleostei: Cichlidae), with notes on diversity of the genus and biogeography of the Río de la Plata basin.
Zootaxa 2982: 1-26

abstract (from publication):
Two new species of Australoheros Rícan and Kullander are described. Australoheros ykeregua sp. nov. is described from the tributaries of the río Uruguay in Misiones province, Argentina. Australoheros angiru sp. nov. is described from the tributaries of the upper rio Uruguai and middle rio Iguaçu in Brazil. The two new species are not closely related, A. ykeregua is the sister species of A. forquilha Rícan and Kullander, while A. angiru is the sister species of A. minuano Rícan and Kullander. The diversity of the genus Australoheros is reviewed using morphological and molecular phylogenetic analyses. These analyses suggest that the described species diversity of the genus in the coastal drainages of SE Brazil is overestimated and that many described species are best understood as representing cases of intraspecific variation. The distribution patterns of Australoheros species in the Uruguay and Iguazú river drainages point to historical connections between today isolated river drainages (the lower río Iguazú with the arroyo Urugua-í, and the middle rio Iguaçu with the upper rio Uruguai). Molecular clocks are used to date these and other biogeographic patterns.
