Legs mainly black
Wing base distincly yellow

Thank you both. Helina deleta would be an exceptional find, Erik, as it has not yet been recorded in the Netherlands. I am attaching a photo of the wingbase but I doubt it's good enough. Look forward to your reactions.

Hi James, I've checked all possible Helinas following Gregor et al's key 8 Radial node setulose and this is the result (with one excluding criterion for our flies):
cilipes => frons male broad
trivittata => frons male broad
decipiens => 3dc post, legs ±yellow
moedlingensis => frons male broad
fratercula => 3dc post
vicina => legs ±yellow
pollinosa => South Europe
consimils => 3dc post, legs ±yellow
crinita => legs ±yellow
ciliatocosta => legs ±yellow
confinis => legs ±yellow

Compared to the description of delete we can see:
? longest aristal hairs about 2x postpedicel
y pra > p npl
y wings intensively yellow basally
y calypters conspicuously yellow
y legs black
y? tibia II 3 p
y tibia III 3-5 av, 2 ad

your male
y? eyes densely pale haired
y very narrow fronto-orbital plates separated by linear frontal vitta
y? tibia I 0 p
? tibia III few elongated p setae
? abdomen densely grey dusted, 2 pairs of spots

my female
y eyes only sparesly haired
? tibia I 1 p
y tibia III no elongated p setae
? abdomen grey dusted, shifting black spots
You'll find the thread here:

Résumé:
I think, both flies are Helina deleta but I'm not an expert!


Greetings, Eric

Eric, thank you so much for your detailed study of this male. I will see what they say on the Dutch forum (Waarneming.nl) and I will report back if I get an answer. I doubt they will accept a new species without a specimen.
