Dear Kathy and Erik:
Well, here goes my id's and comments.
Mike Wise, pls criticize them. As I in my id's will not go deep into
pertensis-meinkeni-"Balzfleck", regani-like fish differences.
Rio Cuieiras:
1. Crenicichla sp.: Kathy, I feel this specimen is C. regani, but not
very sure, bcs the spot near caudal peduncle is larger than usual; if
not a real dwarf pike (like C. regani), then it is a young C. johana,
also common in Rio Negro drainage. Vinny, pls clear us with this.
2. and 3. A. sp. Rotkeil (Red-wedged) [that is possibly same fish as A.
uaupesi], young specimens. At this stage, they are easy to misidentify
as A. pertensis. Bellow lateral line the Rotkeil-Apisto has black points
arranged as lines, this is how I separate both (Rotkeil and pertensis)
when young.
4. A. paucisquamis
5. A. sp. Rotkeil
6. A. paucisquamis; note: the caudal-fin pattern is not clear in some
specimens; if only horizontal stripes, the fish may be A. mendezi,
although all of them seem to be not A. mendezi (that is much more rare
than A. mendezi; from almost 400 A. paucisquamis which I have collected
in Rio Negro drainage, only 3 or 4 were real A. mendezi).
7. Pyrrhulina semifasciata, a species described by Steindachner in 1876,
with type locality "mouth of Rio Negro" (pararypes from other localities
along the Rio Solimões (=Amazonas after the confluence with Rio Negro).
Cow pond:
I think all related to A. regani, and would identify all as so, but in
most specimens in your photos the caudal spot is not extended vertically
as in A. regani (Kullander's fig. 10 in the original description is very
clear about the the shape of the caudal spot).
Mike, pls help me with this id!!!
The other fish is likely a Hoplosternum-species, although there has been
published recently a revision with several Hoplosternum-related new
genera (Cascadura was one of these new genera, I don't remember the
names of the others).
Rio Negro:
1. and 2. A. hippolytae confirmed
3. A. paucisquamis
4. A. regani
5. A. pertensis
Solimões (various):
1, 2, 3 and 4: A. cf. regani
5. and 6.: An Abramites species; as far as I know, only two valid
species within this genus: A. solarii (from Rio Paraguay drainage) and
A. hypselonotus (synonym: A. microcephalus). So, I would id them as A.
hypselonotus.
Creek off Rio Negro:
1. out-of-focus photo, possibly A. pertensis
2. and 3. A. paucisquamis
4. and 5. A. hippolytae
6. and 7. (first plane fish): A. pertensis
7. (second plane fish): A. paucisquamis
Locations can't remember:
1. A. cf. regani
Comments, please!
Marco.
