Hi, I found two specimens of this fly (both females; I think they are the same sp.) near Faliraki, on 16.06.2015 and 18.06.2015, respectively. They are quite sizable, around 30mm. Is it possible to say something about their ID?
Thanks in advance!
Greetings,
Henrik

I can imagine why you are thinking of Neomochtherus (ovipositor?) but the facial gibbosity is too large and the mystax too "full"...... I do not have an answer for you but maybe have a look at Kurzenkoiellus, (formerly in Machimus)....

Hi Reinoud!
Thank you very much for your time and interest! Yes, I guessed at Neomochterus because of the shape of the ovipositor. Thanks to your explanation, I can see now why it can not be that genus. Following your advise, I compared these flies to Kurzenkoiellus, but I think there are a number of of features that do not match, for example the ovipositor is sightly upturned in Kurzenkoiellus, while it it somewhat downturned in these flies, and the color of the large bristles are also different. So it seems these remain unnamed.
Thanks again!
Greetings,
Henrik

We overlooked something that might give us an answer : ) at least for the last two pictures.....There seems to be a row bristles present on the anepisternum/mesopleuron > Acanthopleura > Engelepogon...these creatures might well be Engelepogon sp. > naxia and relatives

That must be it! :) Thanks a lot Reinoud!
Maybe even the sp. could be ID-d at the end...
I post an enlargement showing anepisternum.

In fact, E. naxia seems to fit quite well, according to Engel (as Acanthopleura longimanus Loew).

I ended up there too in Engel, but Tsacas did a revision 1964 and he comes up withe several new species from the archipelago so we will have to study those... too : )
