Possible new harvestman for Wales

I collected this large (leg span measured as 114mm) unfamiliar species off Wendell Thomas' front door frame when delivering his Christmas card today. It looks remarkably like Opilio canestrinii, which according the Spider and Harvestman Recording Scheme website has not been recorded in Wales [id confirmed by Peter Harvey, this being the first Welsh record and to date only noted at 13 other UK sites].
