Hello,
It is probably Campylocheta fuscinervis, that was abundant in Lithuania in April in recent years. Records of this species elsewhere in Europe are scarce. I have no source of newly decribed C. similis Ziegler & Shima and thats why have doabts. Thanks in advance.

HI Erikas

All great finds !

C. similis = C. fuscinervis sensu Mesnil, nec Stein.

The following key is given by Ziegler & Shima:
all with parafacialia bare (at most 5 hairs below lowest bristle; otherwise it is praecox complex)

similis:
Vertex narrow, in male 0,52 - 0,62 x width of eye, in female 0,85 - 0,95. Hind tibia with 2 dorsal preapicals.

fuscinervis (and confusa, for that matter)
Vertex broad, in male 0,8 - 1,0 x width of an eye, in female 1,0 - 1,2 x. Hind tibia with 3 dorsal preapicals.


And don't forget C. mariae Bystrowski !
(seen Tachinid Times)


Good luck, hope this helps

Dear Theo,

Thanks a lot for this key! I have checked a few specimens and it they seem to be fuscinervis, but I have much more material to check. Of course, to be sure I need description of mariae..

Thanks again

---

I have asked description of Campylocheta mariae at Cezary Bystrowski and it is actually in the inepta complex, so the question no longer arises, fuscinervis it is!

---

Thanks for posting this up, Erikas. I have completely neglected similis. I checked my specimens, all fuscinervis. I found the species new for Finland in 2005.. :D Also seemed locally numerous here, but haven't seen it since. Two locations known from Finland. Still waiting for mariae to appear here.

Thanks for sharing the results !

You mean, you are personally still waiting for mariae ?
It has been found by Tiensuu in Finnish Karelia, see Tachinid Times some years ago.
Surely you know ?

Well guys,
I think I foud Campylocheta mariae as well, but Cezary must see it first..
Theo, I thought that Karelia was "liberated" from Finland by Russia ;)

Hi Erikas

You are right. Tiensuu lived at the Finnish site of the (current) border, but his material of mariae was collected as the Russian site.

Yes, the article is familiar... :)

During the war Tiensuu was on a commission in Kentjärvi, which was actually Russian but temporarily "liberated" for few years by Finns. Also all the C. "karelica" material are from the Russian side of the old border. Kolatselkä was quite close to the border though.

So officially the species has never been found within any recognized borders of Finland. I'm sure the air must be swarming of them in the South-Eastern part of the country in the spring...
