Hope this helps,

The Rio Japurá isn't collected much, especially farther upstream. Species that I know that come from this river include A. agassizii, A. bitaeniata, A. cf. pertensis, & possibly A. cacatuoides. In the Colombian part of this river (called the Rio Caquetá) only A. sp. Rotpunk/Red-spot is known from the upper headwaters. I doubt that they will be found in the lower reaches, however. Other possible species I wouldn't be surprised to see from this river include A. sp. Gelbwangen/Yellow-cheeks, A. hippolytae, & Taeniacara candidi. A. juruensis does not come from the Japurá; it is from the Rio Juruá

Hi Mike,

Is it possible, that you don't know, that meanwhile the Ap. sp. "Rotpunkt" is described as A. alacrina (Ichthyol. Explor. Freswaters, Vol. 15, March 2004) by Kullander? 8O

But Kullanders description met with a lot of criticism, because there are no pictures of living specimen or informations about common names in aquaristic (even though it's a well known form), so it's difficult to say, which form of the Rotpunkt group is exactely described (especially because of not exactly known localities of Rotpunkt forms). Koslowski separated these forms, but now they are joined in one species.

greetings,
Rolo

A. elizabethae is from tributaries of the Rio Uaupes.

Rolo,

The original A. sp. Rotpunkt first introduced into the hobby by Kullander in 1974, if I remember correctly, is not included on the list of type material. I believe that wild caught specimens of this form are available in museum collections & could be included, but were not used for some reason. This Rotpunkt form also has black markings that are subtly different from those described for A. alacrina (both the holotype & paratypes). Perhaps this is why Dr. Kullander did not use them. Therefore, I prefer to keep A. sp. Rotpunk/Schwarzsaum/Puerto Nariño separate from A. alacrina at this time.

I am one of the many who have problems with Dr. Kullander's description. Some of his diagnostic features do not appear on the material collected with the holotype from the Guaviare system. They only are seen on paratypes from the Rio Orteguaza (= A. sp. Rotpunk Ortequaza in Koslowski 2002 & Aqualog's SACII as A. sp. Red-point I). Other features are seen only on the holotype form and do not appear on the Orteguaza paratypes. The two collecting localities belong to 2 different river systems, indicating that population isolation presently exists. I fear that Dr. Kullander has mixed 2 closely related forms together and that no fish from the wild will show all of the diagnostic features described in the paper.

Hi Mike,

these are quite interesting informations. Thank you.
I talked to Frank Schäfer a few weeks ago, who published an article about this description. He told me, that all these Rotpunkt forms have to be called A. alacrina. As far as I know (and as Volker Bohnet told me) is the type location of the original A. sp. Rotpunkt unknown, so it's impossible to separate or mix these forms clearly without pictures of living A. alacrina. Anyway, Frank also told me, that the "original" A. alacrina is the Caqueta form, but if I read the description correctly, the Caqueta form ist just a paratype and the holotype is from Rio Guaviare/Rio Ariari. So I'm a bit confused... maybe I misunderstood him.
Did you asked Ingo for his opinion? (or does he not want to know anything about Apistos any longer? *g*)

greetings,
Rolo

 

[patrick1]

are there any more species of dwarfcichlids out the rio japura then only a. rotpunkt?>

other species then apistogramma maybe?> nanacara, laetacara< someone ?
