Found in a parcel from China
Looks like false widow, female, extremely dessicated. Giver her some water!
Thank you Mary. Thought it might be. As it’s from China (and thus different from our own) it’s been collected by an arachnid keeper at a local zoo to be taken care of. Evidently it’s none the worse from it’s long journey (China➡️UK) although, as you rightly say, somewhat desiccated!
