The Curly Hair Tarantula, scientifically known as Tliltocatl albopilosus, derives its common name from the distinctive long, curly setae that cover its body, creating a unique fluffy appearance unlike any other tarantula. The scientific epithet albopilosus comes from Latin meaning 'white-haired,' referencing the lighter coloration of these characteristic bristles. The genus Tliltocatl is relatively recently established, with this species formerly classified as Brachypelma albopilosum in older literature and hobby sources.
Multiple common names circulate for this popular species. Most frequently encountered are Curly Hair Tarantula, Honduran Curly Hair, and simply 'Curly Hair' or 'T. albo' among enthusiasts. The Honduran reference reflects one of the countries within its native range, though the species actually occurs across multiple Central American nations. Some sources distinguish between a Honduran color form displaying more golden setae and a Nicaraguan/Costa Rican form with whiter bristles, though these may represent separate populations or even species rather than simple color variants.
The taxonomic history includes the reclassification from Brachypelma to Tliltocatl, reflecting updated scientific understanding of tarantula relationships. Older care guides, dealer listings, and hobbyist discussions frequently use the Brachypelma designation. For practical keeping purposes, both names refer to the same animal with identical care requirements. This species has been a hobby staple since the 1980s, establishing a long track record that confirms its suitability for beginning keepers.
