I spent at least an hour flipping cover in a little foresty bit of guana whilst I was there, looking for amphisbeana or blindsnakes to no avail. Two species were very abundant though. One was the cotton ginner (a tiny sphaerodactylus gecko we've featured before). The other was this tarantula.
There were absolutely loads of them - sometimes 2 or 3 under each log but they seemed confined to this particular glade - I didn't find any at the higher and drier elevations. The above shot is a crop - the full shot shows that this one had just moulted (which may explain why it didn't run away unlike all the others).
