Hello,

can someone help me with this ~ 7 mm ("estimated", I measured the twig afterwards) Heleomyzinae? I found it basking in the sun in a deciduous forest.
Using Illustrated draft key to the UK genera and species of Heleomyzidae by Sivell, Stubbs and Andrews (November 2024) https://dipterist...cheme/home I got to Gymnomus spectabilis.

I think I got all relevant characteristics from the key. But are there any other similar species in Germany that could be considered?

Northern Germany, Hildesheim, 28.12.2024, 233 m, ~ 7 mm

- dark spots at bases of dorsocentrals
- strong costal spines


- katepisternum with 1 strong bristle in upper hind corner
- 1 pair of vibrissae, no bristles above vibrissae
- posterior gena lacking prominent bristle


- hind femur with 2-3 anterodorsal bristles in apical third
- mid tibia with 2 ventral apical bristles


- thorax grey, abdomen orange
- anepisternum bare

Thank you in advance,
Stephan
