Andinoacara rivulatus (Günther, 1860)
Vieja.
27-Nov-2012 — A new species of Andinoacara
By Rico Morgenstern
A new species of Andinoacara from the Rio Esmeraldas drainage in Ecuador has been described: Andinoacara blombergi Wijkmark, Kullander & Barriga Salazar, 2012. The new species is very similar to Andinoacara rivulatus (Günther, 1860), which was redescribed in the present paper based on specimens from the Guayas, Tumbes and Zarumilla drainages in Ecuador and Peru. A common lectotype for this species and Acara aequinoctialis Regan, 1905 has been designated. The status of the latter as an objective junior synonym is thus confirmed.
The new species was previously believed to be conspecific with, or sometimes, indeed, to represent the 'true' A. rivulatus. However, the present study demonstrates that this name correctly applies to the species well known in the aquarium hobby as 'Goldsaum' cichlid..
