It is very difficult to see, due to the light.
Do you remember the abdomen ?
was is greyish or yellowish ?

Well, I was afraid of that. I'm lost

The femora suggest fulvus, as does the antenna.
The general colouration suggest rusticus.

Using a dice is not very scientific, so this is where it ends for me.

One year later i have come to the same place and found the same fly, more collaborative....

Posted by Zeegers on 01-08-2011 20:34

The eyes are hairy, how could I have missed this a year ago ??
SO that suggests A. latistriatus. However, it looks completely different !
Any change you have a picture in which we can see a palpus laterally ?

Thanks

I'm getting more and more confused. This is a species you are not supposed to have in Spain.
Could you describe the habitat where it was found ?

Thanks

note there is no appendix to vein R4, and the linear callus both unusual for Atylotus. I think Theo has 2 names he is considering, either would be an exciting discovery. One is from the North and the other is an enigmatic Meditteranean one;)

Habitat: very special one, very excepcional: an acid pond with Potamogeton natans, Scorpidium scorpioides, Utricularia minor, Carex lasiocarpa (very rare in Pyrenees) and C. limosa, Equisetum fluviatile, Menyanthes trifoliata, Drosera longifolia, and rotundifollia, rounded by Pinus uncinata... It is a very scarce place where also occurs relicted dragonflies tipical from boreal ecosystems, for example.
I have to come back soon and if necessary i will try to found the fly, if i found, so let me know...

OH MY GOD

Acid pond, that is what I'd love to hear !!

it is Atylotus plebejus (or just possibly sublunaticornis, need to work on that to be very sure: but that would be even more spectacular)

NEW for the IBERIAN PENINSULA.

No wonder I didn't think of it before !!!

Excellent work, excllent pics, my mistake last year.

I will come back to you on this.

Mmmm... it is a very hidden place... take portuguese Oporto wine with you...

I'm 99,8 % certain it is Atylotus plebejus, not sublunaticornis. The question is whether the hairs on occiput are white or black. In at least two pictures, they are clearly white. Picotverd might check the 'original' on this (or PM me I and will).
Great discovery, picotverd, it needs to be published !!

So, to be clear to all: Atylotus plebejus is now beyond any doubt.

Thanks

Does somebody in France has information on the presence of plebejus/sublunaticornis in France ?
I'm aware that Leclercq did mention only sublunaticornis from quite some localities in the Alps. Chvala et al mentioned only sublunaticornis, apparently based on Leclercq.
However, Leclercq identified the material wrong, at least proven so in Belgium and Netherlands: most of his 'sublunaticornis' actually is plebejes.

So, that why I am curious on new information if available

Thank, Theo

Theo, could you say something about Leclercq's species A. venturii, which also has hairy eyes and a linear callus - Portillo mentions a single record for Spain in his book.

Not so grey and with very thick palps.

The habitat 'acid pond' very clearly indicates sublunaticornis or plebejus.

Venturii, to the opposite, is a 'warm' species.

The calli are very variable in Atylotus (that is, they are small, but otherwise very variable) and of little use.

Theo, is it Atylotus plebejus or Atylotus plebeius?

Atylotus sublunaticornis is present in France. Atylotus plebeius I put as an interrogation point...

Hi Theo.

Back a few hours ago from the fantastic Pyrynees. Just fantastic indeed. I'll email you to tell some news. ;)

I saw that info in faunaeur.org.

OK, faunaeuro.org is unreliable in this, because Chvala based his west-European records on Leclercq (so it seems).
The record of sublunaticornis for NL is 100 % incorrect !!

Theo

#32

So, it must be updated and rectified...

And what about the restrictive name?

Posted by Zeegers on 14-08-2011 15:48

#33

Well, I'm not the author of faunaeur.org, .....

I don't understand the last question. Please rephrase.

Is it plebeius or plebejus ?
Eol uses the former.. but I am not sure which is correct.
I also checked here in the nomenclator: http://www.dipter...Recn=52670
