A genus that has been carved apart repeatedly, and the practical consequence is that most of its famous species are no longer in it.
The Costa Rican tiger rump, sold as C. fasciatum for decades, now sits in Davus. Other species have moved to Spinosatibiapalpus and elsewhere. What remains under Cyclosternum is a smaller residual group of small Central and South American terrestrials.
That history is the reason to read this page. A large volume of listings still use the old genus name for animals that formally belong elsewhere, and those listings frequently sit below current market because buyers search the new name. Cross-referencing both names here is a repeatable way to buy the same spider for less.
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.
