I was expecting these to be Canace sp., but they don't have the bristles on the cheeks, or at least only along the bottom edge, not in the middle of the cheeks. They are in alcohol.

They were collected from an intertidal rock outcrop in a beach, Tywyn Aberffraw, Anglesey, North Wales, 19 July 2016.

Thanks. In the AIDGAP key to families it came to Tethinidae or Milichidae, but there was something that didn't fit either, but I'll have another look. One of the two previous North Wales records of T. illota is from Tywyn Aberffraw. Can you recommend a key to Tethinidae, please?

That was quick. Thanks very much. T. illota looks to be correct just from the photos, but I'll take the key home and make sure.

Thanks Paul, interesting point

'Holding' might not be the perfect description. Apparently the armature makes contact with sensitive places on the female, coaxing her to agree to mate.

16.11.17 13:43
Is was not quite sure whether the word would apply correctly, but, yes, that is okay.

15.11.17 11:29
How about armature, would that fit? based on http://onlinelibra

.2008.00422.x/pdf
it would seem that these spines etc are used to hold the female!

14.11.17 09:22
All spines, ridges, lobes, etc. on the femur.

14.11.17 08:36
I think bewaffnung is like weapons (on femur 1).

Hello can any1 tell me how to translate bewaffnung des femur 1? Thx
