Need help with some ID!

[Azizan M Zen]

I've got a chance to obtain some specimens recently. However, all their ID have been mixed up by my supplier.

I have lousy camera skills. Please pardon me, will try to take more photos soon.

What species (names) did your supplier mix up?

 

[Azizan M Zen]

@mike,
These are the names that I got, there are some species that died during quarantine unfortunately. Therefore, I couldn't get their pictures.

D50
D12
Lineata
Sp. Tame
Megaptera
Breitbinden
Mitu
Viejita
Hongsloi
Olga

It's hard to ID species from just a few photos, but here are my guesses (left to right, top to bottom):
Photo 1: Weird dark markings; the caudal peduncle marking remind me (vaguely) of an ortetai-subcomplex species, but can't say from this photo.
Photo 2: Same species but different mood??? Looks like a young male of the brevis-group. Can't say more from this photo.
Photo 3: Probably sold as A. sp. D50, but based on the caudal spot shape looks more like D10.
Photo 4: Same fish as above.
Photo 5: iniridae-group species; probably A. lineata, but hard to say from only 1 photo.
Photo 6: Definitely a Mitú-subcomplex (alacrina-group) species. Probably A. sp. Mitú.
Photo 7: Since I see no dark markings on the body it is hard to ID.
Photo 8: macmasteri-subcomplex species. A. viejita?

FrankH is more familiar with the recent Colombian imports, so he might have better ideas.

Here are my ideas:

1: I agree with Mike, very weird dark markings! We definitely need to see more photos of this fish. The ones in the background look like A. cf. personata to me (see 2). Since the latter often show a blackend vertical bar 7 below the lateral band, this fish might be A. cf. personata too...
2: A. cf. personata (or less likely A. sp. D39, but in this case they should show vertically extended black blotches in vertical bars 2 & 3 sometimes).
3: one of the A. cf. alacrina forms
4: same as 3
5: probably the one sold as A. lineata, but the caudal pattern of this specimen looks more like A. flabellicauda to me.
6: I agree with Mike, A. sp. Mitu (but based on just one photo of a single specimen and without information on the catch location, it's impossible to exclude that it might be one of the closely related forms like A. sp. D53...).
7: as Mike said, impossible to be sure without seeing more of the dark markings. However, given that it is a Colombian species too, my guess would be A. velifera.
8: A. sp. Schwarzkehl or A. sp. D29 (I'm not able to distinguish these two forms other than by their catch location...).

Hey Azizan, very nice fish! It was good to see them that day

Hi Mike and Frank, it's always awesome when you guys shine light on taxonomy stuff. Thanks for that!

Yesterday I visited a friend (Edwin) who also obtained some fish from this Colombia shipment. These two fish below are the same as the ones in photos 3 and 4, but one specimen has bright yellow ventral fins. Would this feature help with ID?

Thank you so much boofeng, for adding in the photos. I'm having a hard time taking proper photos . I'll try to get more photos soon!
