Ahh, does this mean that females cannot reliably be identified ... or just that it is a female
C.latigena ? :)

Chris,
latigena is a rather southern species, you shouldnt exclude mariae that has strongly modified female postabdomen..

Thanks - is there a better key for
Campylocheta than the one in Tschorsnig & Herting (1994)? I noticed it doesn't have
C.mariae :)

If you check Erikas recent post, there is an easy habitus difference, incl. the lack of strong costal bristle. Same as for the male; to my opinion both
C. praecox.
C. mariae and
C. ziegleri(!!) were described only recently (2001), so that's why they're not in T&H. Shortly: genal dilation black haired, strong costal bristle, wings without infuscated spots, tibia almost black, parafacial narrower than third antennal segment. -->
mariae
Otherwise as above, but parafacial wider, mid- and hind tibiae yellow and male terminalia different -->
ziegleri.
Always nice to dig through some strange specimen sets, never knows what to expect..:)

Thanks - I have had another look and I agree with
C.praecox now - it has many more rows of black bristles behind the head than
C.latigena should have :)

I just wish to add to Jaakko`s comment that tibiae are dark in mariae males only, while in females all tibiae are usually reddish!

Thanks for that - I have added all comments to my copy of T&H. Has anyone tried to modify T&H to insert the new species into the couplets? :)
