Right area, but....

Hi Joe

It certainly has 'Haplophthalmoid' sculpturing, but the bumps are extremely exaggerated and rounded (rather than ridge-like, as seen in Haplophthalmus species). Also Haplophthalmus is unable to roll into a perfect sphere. More clues given if needed!

Hi vburton

The 'greenhouse' one is Reductoniscus costulatus. It looks more or less the same, but has more ocelli and only lives indoors within tropically heated glasshouses (Kew, Eden, etc).
