Re: Tephritid for ID

I don't think this is cometa - more like divisa, I'd say

Re: Tephritid for ID

Thanks Tony.

Aargh.  Iím not doing well with these tephritids with a completely dark cell sc.  Never knowingly seen divisa and this is the second fly this year which may be that (earlier post pointed that way by Laurence Clemons but case not fully resolved - http://www.dipteristsforum.org.uk/t7190-Tephritid.html).

I suggested cometa for the current specimen as it seems to key to that in Ian White's 1988 RES key and looks like the wing in his Fig. 281 - of course divisa is not in White as it was only added to the British list in 2006?.  Looking again at Fig. 281 I suppose specimen has too much dark marking in the discal cell to be cometa?

The wing pattern for divisa is illustrated in Bernhard Merz  Insecta Helvetica 10 Tephritidae, 1994, at ABB. 52 i .  I agree specimen looks rather like that.

Specimen is quite small at winglength = 3.4 mm.

ID confirmable or specimen needed please?
