Really not sure what this small spider is, tossing up between some sort of jumping spider, or a small Lampona. None of the Lampona seem to have white markings on their cephalothorax. Jumping spiders like Sandalodes seem to have markings on the centre line
Thanks for the suggestion Michael. It does look quite a bit like https://www.inaturalist.org/observations/26311743 which is suggested to be Aphantaulax. If I see it again I will try to get photos of the eyes. It was quite fast moving and not keen on posing.
