Hi everyone,

Here is specimen caught close to my previous specimen H montana in the Pyrenes.

I believe this is H distinguenda, with those yellow hairs on reddish abdominal part and red on 4 tergites (and fin space between eyes).
To confirm, I looked to find subgenital plate. In order to do so, I tryed extracting what lies under last sternite, but I only manage to find an hidden sternite.

Before making another butchery (extraction wasn't succesfull, see last picture), I ask for some advise: do I have to look under last sternite (like I'd do for Sylvicola) or is there a better/other way to do so?

The hidden “sternite” = subgenital plate.

I can see it loud and clear in your pic.

And yes, this should be female distinguenda.

So mistery of the hidden sternite is now solved! Grin
A good thing I didn't butcher this subgenital plate!

Many thanks on preventing that and confirmation! Grin

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
