Sorry, this is trying to use this key : https://doi.org/10.2478/v10200-012-0009-8 Unfortunately, ... and obviously ...  I didn't use this technique :All specimens were preserved in 75% ethanol, then subsequently cleared in phenol-ethanol and mounted on microscope slides in
phenol-Canada balsam by the methods described in WIRTH & MARSTON (1968). Edited by pat_der2003 on 02-08-2023 07:07 |

Hello, I'm back with th dgenitalia following this protocol : 24h in lactic acid then mounted in Euparal. I think it looks better, close to the pictures in this key !

Following the previous key, I see : 1. Male genitalia without an envelope covering entire aedeagus 2. Wing with two radial cells 3. Clypeus not divided into separate sclerites => Dicryptoscena then : 1. Fifth palpal segment as long as fourth palpal segment, with single row of long setae 2. Gonostylus with slender apex 3. ??? I am hesitating between Dasyhelea notata and lucida/stellata, but my preference goes to the description of male notata ... Althought there are two other european species not in this key : D. fulvosa REMM and D. kurensis REMM ... so ? EDIT : in this paper, it is said that D. fulvosa is present from Czech Republic and Azerbaijan. Dasyhelea kurensis is present from Ukraine (Crimea), Romania, Azerbaijan.
