Genus Haploclastus

India's spectacular burrowers, including the purple-washed showpieces that circulate in photographs far more than in collections, and a genus governed by a border before any biology.

India prohibits wildlife export, so every legal animal descends from pre-ban stock and the world supply is a closed European founder loop. That is the entire market structure, shared with Poecilotheria and Thrigmopoeus, and it does not change.

The animals are deep fossorial old worlds: fast, defensive, venom undocumented and treated as significant, no handling, serious substrate depth. The color that makes the genus famous shows on fresh molts and vanishes down a burrow otherwise, which is worth calibrating before paying closed-loop prices for an animal you will rarely see.
