New Geophagus sp : G pyrineusi

Post by Philippe Burnel »

Geophagus pyrineusi a new species from the rio Teles Pires, rio Tapajós basin, Brazil (Cichliformes: Cichlidae: Geophagini)

Abstract
Geophagus pyrineusi, new species, is described from the rio Teles Pires drainage, rio Tapajós basin, Brazil. The new species can be diagnosed from the majority of the congeners by presenting a complete infraorbital bar. Additionally, it differs from all other congeners by several coloration-related character states: flank bars 5 and 6–7 as dark as the infraorbital bar, and almost as dark as the midlateral spot; retention of dorsal melanophoric patch 6 as a distinct mark (not connected to any lateral melanophoric patch), and almost as dark as the midlateral spot in adults; retention of lateral melanophoric patch 1p and almost complete absence of dorsal- and caudal-fin color patterns in adults, among other characters.

Thanks! Would this be Geophagus sp. 'rio são francisco'? It has the complete infraorbital bar, and the dorsal melanophoric patch 6 as a distinct mark. This does not check though: flank bars 5 and 6–7 as dark as the infraorbital bar, and almost as dark as the midlateral spot, but I dont think any Geophagus has these bars all the time

Sao Franscico is a member of the brasiliensis group, does the new one belongs to this group ?

I haven't read the paper yet either, but doubt this species belongs to the 'G.' brasiliensis complex - at the very least, because of it's range.
The Rio Tele Pires is formed in south-central Mato Grosso at the confluence of the Rio Sao Manoel and the Rio Paranatinga
and flows north towards the Rio Tapajos. If the new Geophagus was described from material collected in the Rio Tele Pires - regardless of where
in the Rio Tele Pires, then that puts this new fish about 2,000 kms west of the general ranges for the ten (currently) species in the 'G.' brasiliensis group, which are all relatively coastal at this point. Again, not having seen the paper, it looks like a Geophagus, not a 'Geophagus'!

Although, there is an example of disparate ranges in Neotropical cichlids... the two species of Mikrogeophagus...

Discovery consists of looking at the same thing as everyone else and thinking something different
