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.
