A larger picture would be geratly appreciated;)

Where was this critter collected?

Posted by Kahis on 08-08-2006 21:48

Argh. I've seen a fly like this somewhere, but I cannot recall where. Aaargh! I'll be back in a minute.

Hmm. It does actually look a bit like the extinct basal cyclorrhaphan Chimeromyia:o, but the wing venation does not match. Could we get a closer look of the venation?

I( am definitely not claiming it is near Chimeromyia, but to confuse myself further I'll link to the original paper [PDF, 4 megs!] describing this genus.

Edit: perhaps I should stop serial posting after midnight. :D

A clearer picture would be great. In the meantime, my guess is Chyliza (Psilidae).

Virginia - tabaco capital, approx as south as Turkey.

I was more wondering about the proximity of Florida (Caraibean influences) and Mexico (Neotropical influences).

My other suggestion would be Strongylophthalmyia, but I'm not sure it gets that far south. (Also wrong size.)

For comparison here's my simple page on the European species: http://www.elisan...a/strongy/

Thanks, Kahis - excellent page.
So not Strongylophthalmyia.

AFAIK only one Strongylophthalmyid is known from North America: Strongylophthalmyia angustipennis Melander 1920. The Manual of Nearctic Diptera gives its distribution as 'southern Canada and northern US'. The illustration differ from Your fly by the color of legs (yellow) and shape of apical spot. Important? Perhaps.

There are similarities, which is why I made the suggestion, but your specimen is 9mm, while Strongylophthalmyia are only up to 4mm. Also the wings on your specimen are comparatively short.

Call her: "dear friend, it is an urgency! I have here a fly that I don?t know identity since 1975... and now I have opportunity to kow FINALLY what it could be! But I need the photos now because I have in diptera.info (net forum) "hungry" guys that ask for the photos!!!! So, come on here now. Even you are in Barbados." :DB)

Well, I guess we can wait for a few weeks if the question has been floating around for 30 eyars.

Now we must wait for new and relevant photos!

to tell the truth...im still not sure what the 30 year old question is

As it is pinned I gather you collect insects. Did you collect this fly yourself? In what habitat was it found? What time of the year was it? If you didn't collect it yourself it's maybe wrongly labeled and could be from e.g. South America or something!? It still got to have a name though ...

no i did not collect it
i know nothing of its origins aside from what i have told you
the lable on the fly is practicaly rusted on to the pin
the place may be wrong but the date fits the condition of the specimen

How about packing the specimen up and sending it to someone knowledgeable. Enough people here who would jump to have a go at it... ;)
