[QUOTE="AndrewClayton, post: 235843, member: 28745"] The most recent major revision of the Brachypelma genus occurred in 2020, when the genus was split into two: Brachypelma and a new genus, Tliltocatl. This reclassification was based on molecular and morphological data. The "red-legged" species, such as B. hamorii and B. smithi, remained in Brachypelma, while the "red-rumped" species, like T. vagans and T. albopilosum, were moved to Tliltocatl. Key diagnostic differences include coloration patterns and genital morphology. For example, Brachypelma species typically have red or orange leg patterns, while Tliltocatl species lack these features. Additionally, their conservation status remains critical, with many species listed under CITES due to habitat loss and overharvesting. Species Remaining in Brachypelma (Red-legged group): Brachypelma albiceps Brachypelma auratum Brachypelma baumgarteni Brachypelma boehmei Brachypelma emilia Brachypelma hamorii Brachypelma klaasi Brachypelma smithi Species Transferred to Tliltocatl (Red-rumped group): Tliltocatl albopilosus (formerly Brachypelma albopilosum) Tliltocatl epicureanum (formerly Brachypelma epicureanum) Tliltocatl kahlenbergi (formerly Brachypelma kahlenbergi) Tliltocatl sabulosum (formerly Brachypelma sabulosum) Tliltocatl schroederi (formerly Brachypelma schroederi) Tliltocatl vagans (formerly Brachypelma vagans) Tliltocatl verdezi (formerly Brachypelma verdezi) Additionally: Brachypelma fossorium was moved to the genus Stichoplastoris and three species (T. alvarezi, T. andrewi, and T. aureoceps) were transferred to Tliltocatl but are considered nomina dubia. The revision to this is not freely available, although here is a link to the abstract and if you would like to pay to access you can, the whole revision is on there with subscription access.
