It was provisionally labelled here as a theridiid, but Dr Robb Bennett writes: I noticed an error  with respect to the 30 January spider of Rosemary Jorna –  nice image. Catherine Scott pointed out to us that it’s not a theridiid. For one thing, it has macrosetae (large moveable “spines”) on its legs which, characteristically, theridiids lack. So we had another  look and agree that it is a linyphiid, probably  Pityohyphantes rubrofasciatus.
