Brachypelma vagans?

Ok guys, still can't get any solid info on these but I'm looking to get one. I know it's a terrestrial species that burrows. It will be wild caught and most likely a sub-adult/adult T. Will a 5.5gal 16x8x10 tank be a sufficent enclosure? I can also get a 10gal. I can use a sterilite tub but I'd prefer a tank. Or use the tub as a temporary until I get the T and know it's size then move forward from there?

AphnoopelmaTX made a great educated guess. Those pictures in the links are really bad - they're all looking rather late in the moult cycle when those that got in the hobby fade in colour to dull brown. But even fresh moulted they don't come in colour similar to the St Lucia ones. The reason is that those in all the links are from Martinique, and different stock - here's a fresh one in brightest colours. https://farm1.static.flickr.com/286/31692605392_f4858936a5_b.jpg
But, both from Martinique (typically rather dull) and the St Lucia ones (typically strongly coloured) both morphologically fit with Acanthoscurria antillensis - the male is undescribed, but there's a whole series of them preserved dried in the british museum collection, with those same bright colours as the spider in question.
