I did an import out of Colombia and decided to grab a bag of Farlowella. I knew when I ordered them that they would likely be a few species, and just wanted to share what came in, and get potential ID. I am not in a rush, as I bought these for my own personal tanks, but thought it might be interesting to figure out. I do have a paper I am delving into as well to help with the puzzle.
I have at least two, possibly three species with two rows of scutes, one of which is certainly vittata (over half that came in are this type). I also have some with three rows of scutes.

I will start with the types that have 2 rows of scutes. One type has a very bulbous nose, and a more honeycomb like shape to its scutes. Side view of what i am assuming is F. vittata

There are also what may be? two types with three rows of scutes, otherwise, they look nearly identical but are much more slender, with a short, thin nose. Side view:

Hi,

yes, the one with two rows of abdominal scutes and long rostrum is F. vittata.

The second one with the short rostrum should also belong to the acus species group, my guess would be F. venezuelensis.
A close pic of the head (dorsal or semi-dorsal view) could help, are there any breeding odontodes on the preorbital ridge, does it has a mid-dorsal ridge ?
Also the length of the pectoral fins would be interesting to see.

Finally, the third one reminds me of F. mariaelenae. Do you have a picture of the caudal fin ?

Have they all been in the same shipment (from Venezuela) ?

Cheers,

They were ALL out of the same shipment from Colombia.
I can certainly take a ton of pictures, I have lots more but didn't want to oversaturate the post with too many. I will get the requested shots. Thank you!

I am guessing that the shipment was a mix of collections from both Villavicencio and Leticia so will contain llanos and Amazonian species. I agree on the F.vittata and F.mariaelenae ids. The others might be more difficult.

@msjinkzd I have a PDF of the revision of the genus. PM me your email address if you are interested in looking at it.

Might be easier for you to read as you have the fish in front of you.

I believe she has the paper via another forum

Sorry to hijack this thread, but I'd love a PDF of the revision of the genus. I am fascinated by the minute differences between these catfish and I'd love to know more!
