Hello everyone,

What I see is :

Subgenus :

1. Male genitalia without an envelope covering entire aedeagus
2. Wing with two radial cells
3. Clypeus divided into separate sclerites => Pseudoculicoides (in part)

Sorry, this is trying to use this key : https://doi.org/10.2478/v10200-012-0009-8

Unfortunately, ... and obviously ... Shock 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).

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.
