South American burrowing mygalomorphs outside the tarantula family: compact diggers that line shafts in firm soil and surface mainly to take prey at the entrance.
The keeping is the burrower's program: deep, cohesive substrate, stable moisture, minimal disturbance, and acceptance that the animal is an entrance hole with occasional evidence of occupancy. Venom is undocumented; the mygalomorph no-handling default applies on principle. Females persist for years.
Trade presence is close to zero: occasional single listings on collector provenance, no keeper literature, no price history. The honest structural note is the standing one for the hobby's blank spots: a lone listing's price describes one seller's judgment and nothing else, the identification is only as good as its source, and early buyers are donating knowledge to a genus that has almost none.
The line on each tile: lowest ask per day.
Rarity BETA Rarity is supply, and only supply: the tier is how many sellers have ever carried a species, and for a single seller, how many separate listings. Price is not part of it, and neither is how recently it appeared. Tiers are given to tarantula species only.
