A sp. "Icana"

[blueblue]

After some readings, I start to have some interests in A sp. "Icana",
and I have learnt that Icana's caudal fin has the same characteristics as Eliza's!! Are there any sharings
on this species? Any suggestions will be most welcome. Thanks

Interesting, blueblue, I haven't even heard of this species so it will be interesting to see if anyone can give some information Have you seen any pics?

Yes, i have read its photos from Datz (A161),
and i have probably also seen some specimen in fish stores...
while i haven't kept it before.

A. sp. Içana is a species closely related to A. uaupesi. It is a member of the iniridae-group. Like A. elizabethae & A. sp. Schwanzzipfel/Tail-point, the tail starts out double-tipped, but commonly changes into a spade/lance-shaped form. It comes from the Rio Içana, upstream from the Rio Uaupés on the Rio Negro. Koslowski (2002) gives a discussion of the species, collecting locality, & breeding of this species.

Thanks Mike. A further question, in your opinion,
between uaupesi and iniridae, which one is the closest relative of
Icana? Thanks.

 

[Mike Wise]

Definitely A. uaupesi!

Definitely A. uaupesi!

Thanks Mike. I first thought Icana is similar to Blutkehl, which is more closely related to Iniridae than Uaupesi ...

Remarks: Besides the abdominal pattern as mentioned in Datz, i paid special attention to the horizontal and vertical patterns in the caudal fin... it convinces me that Blutkehl, Segelflossen, Putzer are very closely related to Iniridae because the caudal fin's line-patterns among them are almost the same (which are very different compared to Uaupesi's... )

pictures anyone?

Koslowski (2002) places A. uaupesi, A. sp. Blutkehl/Cutthroat, Seglflossen/Sailfin & A. ininridae in the iniridae-group because they all have a lateral band that enters the base of the caudal fin without a separate caudal spot. More importantly, they all show a reduced number of infraorbital pores. A. sp. Putzer/Cleaner is placed in the velifera-complex of the pertensis-group (together with A. velifera) because it has a caudal spot separate from the lateral band & normally has a full set of cephalic pore (although some specimens have reduced pores on at least one side of the body). I have little doubt that the species of the iniridae-group evolved from a velifera-complex species.

Thanks Mike. Let me pay attention to these features when i check those fish up in fish stores
