I will have another look when i get back from sunny spain. I´m in the internet booth at the moment after having had a few too many pints. A different fish is on the menu every day in the hotel!Emma Turner wrote:I managed to get a few more pics of the other Vaillantella species yesterday:
Before I start work on the new species profile, are we all 100% sure that these are definitely V. cinnamomea and not V. euepiptera, given that all known Vaillantella species are found in Borneo? I've read and re-read Dr Kottelat's descriptions and am wondering if we need close ups of the caudal fin and maybe better shots of the anal fin? There seem to be a lot of areas that correspond to his description of V. euepiptera.... I probably just haven't had enough sleep!

Just got back to bedlam and the English weather!
According to the original description of euepiptera that fish has only 7 anal fin rays but Kottelat gives a count of 8 1/2 or 9 1/2 (read 9 or 10), which overlaps with euepiptera.
All of the other meristical differences also appear to overlap, apart from perhaps caudal vertebrae which is difficult to count on live fish. That just leaves us with colour/pattern, and locality, and morphometrics. The patterns are similar between the two species. Locality may not be useful here. In morphometrics your specimens have the right proportional head length in SL and predorsal length in SL to be cinnamomea not euepiptera.
I cant be 100% because of the pattern problem, but based on what I can see I would lean more towards cinnamomea, albeit with some reservations now (well spotted Emma).
Cheers

I would still go ahead with a Vaillantella cinnamomea profile. I've always known or believed that the Vaillantella euepiptera has a more distinct zig-zag pattern running from it's head to the lower part of the body.

Do you mean the pattern along the ridge of the back (figure 5 in the attachment you linked), or the pattern in the body? If you mean the one along the ridge of the back, the pattern in Figure 5a is present in some of Emma's specimens (see the penultimate image on her post of 24/9/07 at 10.02pm). However, I agree and think that for the time being we should class these as cinnamomea.

Hi Steve. Yes, the pattern along the ridge of the back. I don't know why but for me the lack of a pattern around the head makes me believe that these are Vaillantella cinnamomea. I can only see the markings under the long dorsal fin. The zig-zag markings are known to be strong from the head down-wards on the Vaillantella euepiptera. I'll agree with you on agreement with this one, Ooo shaded one.

Thank you. 
But......to put my mind at rest, does anyone have access to a photograph of a live V. euepiptera specimen? I still have a few doubts as to whether these really are V. cinnamomea because of the species comparison descriptions in Dr Kottelat's V. cinnamomea paper.

When looking at these in the tank alongside the V. maassi, the general body colouration looks the same and some specimens have what I would call jazzyish markings along the dorsal surface.
