Super Administrator Location: Reading, England Posts: 7706 Joined: 12.07.04	Thanks - is there a better key for Campylocheta than the one in Tschorsnig & Herting (1994)? I noticed it doesn't have C.mariae Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London.

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..

Super Administrator Location: Reading, England Posts: 7706 Joined: 12.07.04	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?
