Hello,
I have two specimens of
Hybomitra species of
bimaculata group to confirm.
Found in a alkalin marsh (by Malaise trap - 31/07/2024).
- notopleural lobes yellow/orange
- first and second antennal segment orange
- basal callus brown
- orange on tergite 1-3 and a orange spot on tergite 4
- black hairs on tergite 2-3
- cercus short not rounded
- subgenital plate with basal notch
With light notopleural lobes,
bimaculata is exclude,
distinguenda doesn't have black hairs on tergite 2-3 (and a different subgenital plate) and
muehlfeldi have the two first antennal segment grey and not orange. Cercus are quite different.
So for me :
solstitialis
The only difference with the second specimen (second post) is on venter : here, we have a dark median spot on tergite 1 with an clear extension on tergite 2.
