In my opinion it is very dangerous to try and identify or confirm species identification of complex male palps, especially but not exclusively, in linyphiids, from photographs without being able to examine the whole palp oneself and the whole spider, for the reasons I have already given. There is a world fauna out there which has to be considered as well as the known British fauna, as unexpected species continue to turn up in this country, some recent arrivals, but by no means all. Wet grassland is a very odd habitat for D. latifrons, which is normally a spider of leaf litter in woodlands

Diplocephalus latifrons (?)
Thanks

Interesting, as I have been told that there is sufficient detail with the characteristic 'claw' to identify this one to species. Although I don't have the larger Roberts online references appear to confirm this. What are other candidates?

Sorry, can't be done from photos - male palps of most spiders and Linyphiidae are too complex and 3-dimensional to enable accurate identification in this way, since one needs to see other details of other parts of the spider and of the palps at different angles to be sure of anything. You are welcome to post the specimen to me at 32 Lodge Lane, Grays, Essex RM16 2YP

Many thanks Alistair. Your Araneus quadratus will be juvenile at this time of year, but is recognisable as a large juvenile. Records for this species can be submitted directly through the Four Spot Orbweaver page, but I will enter your record into the database.

By way of record submission, here's a poor shot of a semi-drowned Araneus quadratus from NT187875, 10/03/2015

Dear Lee

It is impossible to sure of much from the photograph, but it is most likely to be Amaurobius ferox, a local 'lace weaver spider' usually found under debris and stones etc in gardens or near buildings. It is harmless to humans.

Enlarging and lightening the image makes it clear it is not a tube web spider Segestria species.

best regards

Peter Harvey

Unknown large spider - Derby DE21
I have seen similar looking "stocky", jet black spiders before but none quite as big as this beauty!

This was at the bottom of a hallway with stairs leading up to 2 flats. Location is DE21 4LU, Derby.

Unfortunately I'm quite heavily arachnophobic and this was as close as I dared to get. I believe it's possibly a tube web spider?
