Is Peleteria rubescens the correct name? Animal collected in Portugal in the vicinity of Porto on the 26th of August. Size around 13 mm. Thanks in advance Auratus attached the following image:  [130.99Kb] Edited by Auratus on 15-09-2011 13:37 Greetings, Jan |

I don't think that it is P.rubescens because that species should have long palps ... I can just see the tips of palps on this one. If I follow the key I come out to P.meridonalis but that is very tentative because I cannot really see all the features clearly and this genus isn't very easy

Yes, that is absolutely possible, because P. meridionalis is missing in my key. When i look in the gallery however, P. meridionalis has a yellow second antenal segment. Thats the first couplet in my key, and the reason why i rulled it out. When i check the palps (not part of my key) under the microscope, i would say they are rather long and slender in this specimen.

Would you say that the palps are about 3/4 or more the length of the haustellum or only 1/2 or less as long as the haustellum? In my key it says that rubescens is usually heavily dusted on each segment but yours looks relatively undusted. Which key are you using? Do you have Mesnil in Lindner (Die Fliegen)?

The palps are indeed about 3/4 of the length of the haustellum and the animals (i collected 3 of them) are all heavily dusted. The dusting is just not visible on the foto's due to the light. The key i use is the key of Tschorsnig and Herting (translated by you? (i guess )) for the Central European species, since i don't have a key for the Southern European species.

Hmm, OK - given long palps, black 2nd antennal segment and lots of dusting then it is probably P.rubescens  If you send/donate me one then I can try keying it here and comparing it with the others in my collection but from what you say it seems to run to rubescens, unless Theo knows any other alternatives? I am using Mesnil in Lindner here ... a rough English translation of the Peleteria section ... but it is very old and there might be alternative species.
