Kullander's 1980 original description lists A. meinkeni sympatric with A. uaupesi, A.
brevis, and A. elizabethae. This is the only confirmed location for this species, but a
wider distribution is probable. A. meinkeni - or one or two very closely related
species - is reported from the Rio Tefé on the Rio Solimões and comes in with apistos
from the mid-lower Rio Negro (A. pertensis & A. hippolytae).

I strongly recommend the original description of A. meinkeni by 
Kullander, 1980: there is a black & white picture of a preserved 
specimen, but you can count about 6-7 dark bars on caudal fin.  It must 
be noted that the clear interspaces are broader (when closer to caudal 
fin end) than the dark bars or about same size (when closer to caudal 
peduncle). Worthy to check the picture.

Cheers, Marco.

Dear Mike:

You can find it at a library.
Look for: "Bonner Zoologische Monographien, Nr. 14, 1980". This is 
Kullander's paper containing A. meinkeni's original description, as well 
as many other species.
I agree with what Mike Wise suggested, i.e., that A. pertensis is not a 
single, but a complex of species. So many of the so-called A. pertensis-
populations, A. cf. pertensis, A. aff. pertensis or ditto for the A. 
meinkeni in the hobby should represent distinct, closely related 
species.
I've collected myself the real A. meinkeni (from type locality, the 
village of Trovao at Rio Uaupes) and can tell you that the light 
interspaces are always broader or equal in width to the dark bars, just 
exactly as in Kullander's picture. I have preserved a few specimens (now 
deposited at the NR Museum in Stockholm, where Kullander works) and have 
a slide from this specimen (dead, after preservation in formaline, but 
caudal fin pattern clearly visible).

The real A. pertensis, like Mike Wise said, is best referred to as 
Haseman's photo/drawing.
It's a fish from Rio Negro.

I've collected some fishes like A. meinkeni, as the so-called A. cf. 
meinkeni "Tefé", but it may represent another distinct, closely related 
species. (I've shown a slide of this fish at last Apistogramma Study 
Group lecture in St. Louis).

Cheers.
