Looking for species I.D. from TomC "Collecting in Río Tigre / Río Pucacuro 2010"

I've been doing some research trying to find a Genus sp. name for a tetra that appears in TomC's "Collecting in Río Tigre / Río Pucacuro 2010" collection trip notes and gallery. Specifically the one found the last day with A. pantalone and A. martini in the trip notes, shown here in the following photos from his site with Nannostomus morthenthaleri:

I'm hoping that he sees this and can comment, or if anyone else can tell me what these tetras are. Based on pictorial representation, the Peruvian Red & Blue Tetra (Hyphessobrycon sp. Red-Blue Tetra) or this one from Aquarium Glaser are similar, but neither of them are close enough for me to think that it is either of the two. The closest I've found is the fish from this Twitter post, but there is no positive I.D. there either.

Thanks everyone!

Maybe close?

It could be, but Peru isn't listed as the distribution locale for that species anywhere, and this particular fish is from a smaller creek tributary of the Rio Tigre somewhere downstream of Intuto, between Intuto and Nauta in Peru.

Be aware, that especially for tetras the distribution is not always set in stone, especially with the more obscure undescribed and lesser known species. So always take infos about the locales with a grain of salt and expect them to crop up from somewhere else sometimes.

MacZ is correct. Realize that the paper lists the 'type locality' and known distribution at the time of its description. The actual distribution of a species can be much larger. I have seen this species and several other 'red-line' tetras appear in nets in many locations when collecting in northern Peru with Tom.

I can appreciate what you both mean about the distribution being larger than what is officially documented. I only mentioned the type locality because it was specifically stated as the location where the particular specimens in the photographs were collected. I thought it might be helpful to identify the species.

Is this an as-yet undescribed species then? Do you think the fish from the Twitter post, and the "Hyphessobrycon sp Super Red Line 'Rio Tigre' " Blogger page are the same species?

I'm trying to get a definitive I.D. so I can keep an eye out for them as well as A. martini and A. pantalone in the trade.

It appears to me that it is indeed what CRD suggested. Also, as Mike and Mac both stated, the distribution is more than likely wider than just Rio Tigre and it's tributaries. See this blog post (I translated from Chinese to Enlish in Google Chrome, YMMV).

I sent your pic down to a friend and shipper in Iquitos, Peru and he calls it "Tetra Red line". He does not think it has been described yet. and he did confirm it comes from the Rio Tigre area.

Hi George, I sent you a PM.
