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)...

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

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
