The tarantula genus Sericopelma was originally defined based on male specimens, most notably lacking tibial spurs on leg I. Early female specimens were unrecognised as Sericopelma, and typically placed in Eurypelma \– a dumping ground for problem specimens. The first females were only later recognised, but authors failed to adequately define female Sericopelma. Here, the holotypes of the Southern-most alleged Brachypelma species, B. embrithes (Chamberlin \& Ivie, 1936) and B. angustum Valerio, 1980 were examined, and finding both to possess defining characteristics of Sericopelma were transferred. The taxonomic attributes to define Sericopelma relative to Brachypelma and select other Neotropical genera are discussed, especially for females. As important diagnostic characters for Sericopelma, the single (unilobar) spermathecae swollen at the apex forming a P-shaped cross-section, metatarsus IV with trace scopula, femur IV with a dense retrolateral pad of plumose hair, plus other attributes. Some past confusion in these characters are clarified and Sericopelma relative to Brachypelma and Megaphobema mesomelas are discussed. Finally recommendations are given about these taxonomic changes for CITES regulations.

The examination of specimens from various Neotropical tarantula genera (Theraphosidae) indicated the unique nature of monotypic genera Mygalarachne [sic] Ausserer 1871 and Harpaxictis Simon 1892. Review of the both holotypes leadsus to argue that Mygalarachne [sic] and Harpaxictis should be removed from their current synonymy with Sericopelma Ausserer 1875. The presence of type I andIII urticating hairs on the holotype specimen of Mygalarachnae [sic] firmly place it inthe subfamily Theraphosinae and we argue should be restored as a valid genus,so that current placement of incertae sedis is inappropriate. The identity of Harpaxictis striatus is less certain, but here removed from synonymy with Sericopelma, and due to a lack of other diagnostic features is suggested as nomen dubium. Possible affinities of Mygalarachne with other valid genera of Theraphosinae are briefly discussed. El estudio de los ejemplares de varios g\éneros de tar\ántulas Neotropicales (Theraphosidae) indican la naturaleza \única de los g\éneros monot{\&$\#$39;{\i}picos Mygalarachne [sic] Ausserer 1871 y Harpaxictis Simon 1892. La revisi\ón de ambos holotipos nos lleva a proponer que Mygalarachne [sic] y Harpaxictis no son sinonimias de Sericopelma Ausserer 1875. La presencia de pelos urticantes tipo I y III en elholotipo de Mygalarachne [sic] apoya claramente su adscripci\ón a la subfamiliaTheraphhosinae y, por tanto, su actual ubicaci\ón como \"incertae sedis\" es inadecuada y debe ser restaurada como g\énero v\álido. Aunque no es una sino-n{\&$\#$39;{\i}mia de Sericopelma, la identidad de Harpaxictis striatus es incierta, y a falta deotras caracter{\&$\#$39;{\i}sticas diagn\ósticas proponemos considerarla como nomen dubium.
