Jason,
this fish was first mentioned by Kullander in the scientific description 
of A. hippolytae (published in DKG-Journal). About three or four years 
ago, I have sent him some fish from Rio Ipixuna (Rio Purus drainage) 
westward from Humaitá that he identified as so.
More recently, in a paper named "Apistogramma aus Porto Velho" 
(published in DATZ), Stawikowski published a picture from this species, 
remarked Bork & Mayland mistake, and said it came from "Porto Velho" 
(obviously a mistake, this is the export city of the fish, not the 
locality where it was collected!).
I've collected it along Rio Ipixuna and its tributaries, in the "praias" 
(sandy shores) sympatric with A. agassizii and A. resticulosa. Both 
agassizii and resticulosa are also found in the Madeira-drainage, closer 
to Humaitá; but as far as I'm concerned, A. sp. Erdfresser is found in 
Purus-drainage only.
It seems to be a A. pertensis-group fish, although lyre-tailed. Not 
difficult to breed, it is NOT from blackwater. Sometimes shy in 
aquarium, like other A. pertensis-group fishes.
Cheers.
