@cold blood Nope, this is a full fledged tarantula. She unfortunately passed not long ago. No idea why, she had just taken a meal about a week prior. Too bad, I've never seen these for sale since then.
@cold bloodCatumiri argentinense is the species. I believe that this is the only species of this genus in the hobby. I couldn't really find any more information on their husbandry, so it was a bit of a guessing game. She seemed to enjoy a mildly humid environment, similar to Acanthocurria. Although, again, I may have made a misstep.
