Hi,

yesterday I took a few pictures of a small greenish fly with a metallic tinge. I would suspect, that it is a male of Dolichopus sp.. Is that correct and/or is it possible to determine the species from the pictures?

Germany, Southern Bavaria, Munich (-West), shrub leaf, 16.06.2024, app. 5 mm

Greetings, Uli

Hercostomus nigriplantis? Note the enlarged mid fifth tarsomere.

Hi John,

thank you very much for the determination. Do you think that could go without a cf.?

I don't have the experience for this kind of determination, but the three criteria listed in the "Grichanov Checklist & keys" seem to be met ("Mid basitarsus without ventral setae; scutellum bare dorsally; 5th segment of midtarsus slightly dilated;").

Greetings, Uli

The key by Grichanov is for Europe north of Germany. I do not know if there are any similar species in Bavaria.

Hi John,

I don't know either, obviously. But thanks for the additional info, I will leave it at Hercostomus cf. nigriplantis.

Thank you and greetings, Uli

Europe has no similar species. Hercostomus nigriplantis.

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
