Brazilian terrestrials, a small genus erected relatively recently, and one where the honest position is that hobby knowledge is limited.
Moderate size, terrestrial to semi-fossorial, and generally calm. Husbandry appears to be standard Brazilian terrestrial: warm, moderate humidity, substrate depth for burrowing when young. That description is inferred from close relatives more than from a body of keeper experience.
Brazilian export closure means captive lines only, breeding reports are sparse, and listings appear irregularly. There is not enough transaction history to say whether prices are trending. If you buy one, you are early, which cuts both ways.
