I bought 2 pairs of these 6 cm.+ Pyrrhulinas recently but I'm struggeling a bit to identify it. The shopkeeper couldn't remember where they were imported from.

I have an eye at P. filamentosus, but not shure at all...

Yes I feel for them right away!

I've had a suggestion for Pyrrhulina laeta "Rio Magdalena" at another forum...not many pics on Google though.

No idea either, but it's really beautiful. /cool.gif" style="vertical-align:middle" emoid="B)" border="0" alt="cool.gif" />

On P. laeta, it was described from northern Peru (río Ampiyacu) but according to the Géry book the type specimen lacks the anterior portion of the body including the head! Don't know if it's been redescribed since but can't find a reference if so?

P. lugubris is the only species in the genus described from Colombia and the types are from Barrigón, not too far from the Río Magdalena mainstream. Anyone know what that one looks like?

There are a couple of pictures on p. 23 (11th page of the paper) of P. lugubris in this:

http://www.vertebrate-zoology....../vz61-1/02...61-1_Zarske.pdf

And there are certain similarities there too.

Given the geography (if we can trust the Rio Magdalena-detail) and the pic of P. lugubris in Plesners link I think it's a very possible ID.

Great link. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Maybe interesting that two of the specimens there are labelled as collected in Guyana though?

Taphorn (1992) states that P. lugubris occurs in the Orinoco basin and describes its live colouration thus:

The body is purple in life. A narrow black stripe extends from the snout, passes back through the eye, and continues a few scales behind opercle. The sides are marked with several rows of red or orange spots. The dorsal fin has a dark black blotch and is edged anteriorly in white. The margins of the anal, pectoral and pelvic fins are black in males.

Hmm...mine has some red/orange in the dorsal and blue in tha caudal instead of black...

But in the link Plesner provided above it says:

Der schwarze Fleck in der Dorsale ist bei P. lugubris
in der Regel größer und distal spitz zulaufend. Allerdings
kann in manchen Populationen bei lebenden
Tieren dem schwarzen Fleck ein roter Streifen vorgelagert
sein, so dass der schwarze Fleck sehr schmal erscheint
(Abb. 10 bis 11).

...so they CAN show red colours in the dorsal.

Aha. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Wonder why Zarske doesn't discuss distribution in his paper?

Yes, would have been nice. Anyway, P. lugubris seems to be a very close match.
