Thread subject: Diptera.info :: female Asilidae : Dysmachus fuscipennis ??

A friend sent me a picture of an Asilidae. She said it was approximately 18 mm. I think it might be a female Dysmachus fuscipennis, but I don't know the species. Is it possible to make a determination based on these pictures ? Another suggestion is Eutolmus rufibarbis (automatic ID observation.org)...

Thanks in advance, Tjitske Lubach

Hi Tjitske,

I agree, the front femur with bristles excludes Didysmachus, furthermore there is only a short pile of hair on the ovipositor anteroventrally while for Di. picipes you would expect an ovipositor with long hairs antero-ventrally.
Eu. rufibarbis can be excluded the easiest on the form of the ovipositor as the ventral margin would have an "sinuation" and the cerci would point upwards.

Best, Jonne
