Hi,

my camera just managed to focus on the mirror image, but hope ID is possible nevertheless.
Psila fimetaria?

Looks quite delicate for Psila, so it might be one of the pale Chamaepsila, but difficult to say without indication of size.

I am now very confident that Paul is right in his opinion that this is a Chamaepsila species. Eye shape, apparently two dc pairs exclude Psila.

I have a species list of Chamaepsila for Austria that comprises 16 species. It doesn't include Ch. lutea (is that a valid species?) and I don't have information about the characters of Ch. andreji, so I am left with 3 species having a yellow thorax and abdomen: Ch. obscuritarsis, Ch. pallida & Ch. rufa.

I am almost certain I can see two dc pairs (which also excludes Psila), which leaves me with Ch. pallida. Also the third antennal segment is darkened, which is ok for Ch. pallida (according to HENNIG; I don't have new literature).

Is anyone with me? awkward

Cheers,
Lorin

Hi Carnifex,

Besides the extra pair of dorso-centrals Psila lack post-vertical bristles.

For a definitive species ID I'd need to know scutellar bristles, how many verticals (vt) are present. The ID looks to be a female C. pallida indeed. To be sure I'd have to examine the specimen...

Greetings,

Ectemnius

I might add that this is a great resource and I am really thankful for all the members help.

Thanks for the explanation Paul. It definitely stopped me from flooding the forum with my threads Wink

Each user has a maximum of ten new threads per day (24 hours). Just to prevent a single user from sending scores of his unidentified fly photos at once and thus drain out any other threads.

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?

SabineH: you have to be logged in to see "New Thread" in the right upper corner of each "forum" site. In the case of accidental logout you have to start over.
