Abstract
As part of an ongoing taxonomic revision of the genus

Heptapterus

from the Laguna dos Patos and Uruguay River drainages and Atlantic coastal streams of southern Brazil and Uruguay, two new species closely related to

Heptapterus mustelinus

were identified. Both species are endemic to small tributaries of the Uruguay River. The two new species are distinguished from each other and from other species of Heptapterus by arrangement of cephalic and trunk laterosensory systems, number of vertebrae and number of dorsal, pectoral and anal‐fin rays. Phylogenetic analyses of mitochondrial DNA (coI and cytb) sequence data further supports distinctiveness of the two new species.

Heptapterus carnatus

Heptapterus exilis

Too bad it is not open acces. I wondered whether I've kept one of these new species or not.

Thank you

The fishes I've kept came from the south of Uruguay - and the new speceis from South Braqsil, actually quite close to the Uruguay border.

So I did not keep them.
