Southeast Asian fossorials pulled back out of Haplopelma and Cyriopagopus during the ongoing reshuffle of that whole group. M. albostriatus, the Thai zebra, is the one with real hobby history.
Burrowing, defensive, fast, and mostly invisible once established. They build deep and they stay down. Adult size is moderate by Asian standards and the striping is genuinely sharp on a freshly molted animal.
The genus is a naming problem more than a keeping problem. Because the species have moved between three genus names within a decade, the same animal appears in listings under all three, and there is no reliable price convergence between them. This is a case where the buyer who knows the synonymy pays materially less than the one who does not.
