Huntsman relatives in Sparassidae, Asian, and a genus where I would rather say less than guess.
They are flat, nocturnal, fast, and arboreal or bark-dwelling like the rest of the family, and hobby husbandry follows the general Sparassidae pattern: vertical cork bark, cross ventilation, moderate humidity, and an enclosure you open carefully. Beyond that, accumulated keeper experience with this specific genus is thin.
Supply is occasional Southeast Asian wild-caught material with no consistency, and species identification in the trade is approximate at best. If you buy one, you are buying a huntsman of uncertain species with limited published guidance, which is fine if that is what you want and worth knowing if it is not.
