I was thinking the same thing, John.
it resembles Trichogena rubricosa with the mid stripe, pale tip of scutellum, wing venation and chaetotaxy. Any other angles?

Best wishes,
John

Thanks to both of you, I did not think about Rhinophoridae because of the gray-yellowish color, but Trichogena rubricosa works very well.
Sorry, no different view.

Trichogena is very often mistaken for a Tachinid.

Hi,

isn't it Tricogena (without the 'h')?

Hello everyone,

I think that taxonomists prefer the Rondani spelling, which is Tricogena. So you are perfectly fine with that spelling.

I think it was originally Tachina rubricosa (I could be wrong). Anyway, the name Tricogena is of taxonomical value only since Rondani didn't discover the species. Thus, i don't see why the spelling Trichogena is not accepted. I use Trichogena rubricosa on my unpublished website and i have no intentions of changing it. I prefer the hairy-cheeked definition as opposed to the evasive cheeked meaning.

To each his own.

Best wishes,
John

No problem John, on insect.org we follow Fauna Europaea and INPN who spell Tricogena rubricosa (Meigen, 1824).
As you say, to each his one.
Thanks again.
Eugene

Hello John,

because it makes no sense? It means "generating hairs"... I don't think that the author who introduced the genus name, intended that.
Best regards,
Jürgen

Gena is a Latin word for cheek, also adopted into English language entomology. Typically it means the head below the eye.

Hmm.. I thought it was derived from "generare" = generate.

and it is the origin of jaw, jowl, chew, chin etc.

I thought that i had cracked the secrets of old linguists (exciting!) until i discovered an old French book (via Google books) that had some of my rules. Still i was able to understand the methods without external help so that it pretty cool.

Juergen,
for generare see genus and think of kin, clan etc

Best wishes,
John
