 Hello ereryone,

is my determination correct? And if so, a determination to species is not possible from a foto, if I understood it right. Length 14 mm.

Location: Germany, Rhineland-Palatinum, 53572 Unkel, river Rhine valley, Stux hill, dry and warm habitat (grapeyards), nearby deciduous forest (oak, Fagus ...), July 17th, 2026, about 70m NN; the fly was attracted by light.

Thanks in advance,

Michael

 Hi Michael,

Neoitamus is not correct. This species lacks the forward bending hairs you would expect on the hindside of the head and the ovipositor looks different. Have a look at the genus Tolmerus,

Best,
Jonne

 Hello Jonne,

thanks for your answer. Maybe Tolmerus atricapillus?

Greetings from the Stux hill,

Michael

 Hello Piros,

yes, Tolmerus cingulatus seems to fit better. Thank you for determination!

It is sad news. I read him a month ago, as he replied to me about a wrong identification. He was brilliant, as always.

I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.
