Hi,
this about 2mm long fly was found indoors (probably hatched from a kitchen waste bin). Help with ID appreciated.

Dear Paul, thanks a lot!
With the key from Grootaert et al (2010) I cannot find a definite species, there is always something that doesn't fit. Unfortunately I do not have access to the key by Raffone 2013 - is it possible to get it somewhere?
As you commented at another Drapetis-request from me, are you still interested in this genus? I might send you samples.
Cheers, Lorin

Hi Lorin,

I missed Gianni's paper on the Tuscan Drapetis but requested a reprint. As to having difficulty identifying your specimen, welcome in the real world. :P
Drapetis can be quite variable when it comes to colour and using characters like the length of the setae on the antennal segments is not always quite as straightforward as it may seem. Male genital characters are still the best to identify spicies but we are working on getting some reliable satructural characters for the females as well. Patrick Grootaert and I know of at least two undescribed species so any additional material for our studies is welcome (especially males).
Mind you, males and females from the same date and locality / sample are not necessarily conspecific. I have had sample from a Malaise trap with at least four, possibly five different species.

Thanks for the update, Paul. The other one I posted is a 'flavipes'-type so I have at least two species in my kitchen waste :-)

From experience I now know that not all yellow legs mean 'flavipes' type in the taxonomical sense but only in the morphological sense.
