A Mexican tarantula genus of one species, formally valid, practically invisible: decades in the literature, almost nothing in the trade.
The frame is Mexican terrestrial: New World, urticating hairs, arid-leaning keeping with substrate depth and patience, slow growth, long life. Mexican export closure means anything legal descends from a founder base that may be no wider than a handful of animals.
The trade record rounds to zero, and every standing rule for the map's blank spots applies: provenance is the identification, a lone listing prices in a vacuum, and early keepers write the care sheet. The genus persists as a name waiting for either revision or rediscovery, and its page here is mostly a marker that the name exists.
