Hello, this Suillia was collected the 20th of August 2022 in Ede, the Netherlands, in a muddy area.
I took a lot of pictures and placed them here:

Trying to ID it, with this online key based on Withers (1987) I would arrive at Suillia imberbis.
https://dipterists.org.uk/sites/default/files/scheme-files/Withers%20illustrated%20key%202024.pdf
I was not sure if there was a broad or small median area on the scutellum bare. So I prepared the genitalia to make a conclusion but it did not help me out, because:
- The left and right surstylus seem to fit S. laevifrons
- The aedeagus seems to be different from the drawing of laevifrons.
Can somebody help?
(first picture is the right surstylus)

My picture of the aedeagus seems similar to this one here, identified as
Suillia laevifrons: https://www.spessart-fliegen.de/diptera/heleomyzidae/suillia/suillia_laevifrons/suillia_laevifrons.html
However, it looks different from Withers (1987). See the drawings of Withers (1987) in the attachment.
Or am I wrong and is my picture not the aedeagus?
