another specimen

It's a difficult one ... it is quite elongate in the body and the post-bend part of the median vein is very stretched and concave, suggesting a sarcophagid but ... does it have a subscutellum? :)

Nice insect though - looks interesting :)

does it have a subscutellum?

A good question :@
It seems, it has not

BAsed on these pictures, it might go either way.
My gut feeling says Sarcophagidae, though.


IF you send it, I can get a genus for you.

I think we have seen this one before: Sarcotachina umbrinervis.

Please compare specimen with nice pictures of Rui Andrade:

Thank you Chris and Theo.
Theo, I have a lot of pureblooded Tachinidae waiting for ID to genus and species. When you will have luck of material just let me know!
This fly was somewhat too nice to my test and unusual. I checked that arista is bare and didn't check subscutellum. I dicided that probably I can get full ID of this fly and made image.

Aaaa! Though Sarco, but still Tachina! :@
Thank you Liekele!
Looks very like Rui's fly (I guess Rui's is female, both mine are males).
Liekele, my males have parafrontalia and interfrontalia almost same white dusted (interfrontalia yellowish-white), Rui's fly has much more distinct colour difference of para- and interfrontalia. Is it still OK for S.umbrinervis or I can't be sure in species level ID?

Rui caught both male and female. Male has indeed parafrontals and frons white dusted.

I have checked for possibility of other known species within Sarcotachina, but S. umbrinervis is the only dark species within the genus. Others are very different in appaerance.

So id on species level is ok.

Thank you, Liekele!
So, it was a good idea to make image of this fly :D

To prevent mistakes

Sarcotachina is in Sarcophagidae !!


(so my gut feeling.... was right)
