Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.

Rick C. West is a Canadian arachnologist and an expert on the taxonomy of tarantula spiders. West was born in Victoria, British Columbia. He has been interested in spiders since childhood, and collected his first tarantula, Aphonopelma eutylenum, at the age of 13. He worked primarily as a Chief Constable for a local Animal Humane Society, but also have been involved with the collecting, breeding, rearing and photography of theraphosid spiders. West has traveled to over 27 countries to document and study them in their environment, has been a host, presenter and co-producer in several tarantula documentaries and has also described several genera and species.
Spinosatibiapalpus is a genus of tarantulas erected by Gabriel and Sherwood in 2020 for a newly discovered species and two other previously described species bearing a unique palpal bulb morphology. The name is a reference to the spines found on the fourth section of the pedipalp in adult males. This distinctive feature was also found in Pseudhapalopus species, but because it is never mentioned in the original description of that genus, Gabriel and Sherwood called into question the validity of Pseudohapalopus, and moved all its species except P. aculeatus, known only from a single male found in Bolivia in 1907. It is impossible to place P. aculeatus because the holotype was destroyed when the museum housing it was bombed during World War II, and it has been declared as nomen dubium.
Anqasha is a monotypic genus of Peruvian tarantulas, containing one species, Anqasha picta, first described by Danniella Sherwood and Ray Gabriel in 2022. The type species was initially described under the name Hapalopus pictus in 1903 by Reginald Innes Pocock, but was later moved to the Homoeomma genus, until finally becoming Anqasha. Its name comes from the Quechuan word for blue, "anqash".
