Here is a pseudoscorpion from Warnham Local Nature Reserve leaf litter leaf litter sampled 14-Mar-2019, here in Horsham UK. I think it may be Chthonius ischnocheles, but would appreciate confirmation, or otherwise. The specimen was mounted in Brunel Alcoholic Mountant (BAM).

EDIT: I had some correspondence with Gerald Legg (who co-authored the FSC key), and based on the epistome and the galea on the cheliceral finger he concluded it is probably C. ischnocheles , so now have come full circle after considering some alternatives.

Though we lean upon the same balustrade, the colours of the mountain are different.
