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&eacute;neros de tar&aacute;ntulas Neotropicales (Theraphosidae) indican la naturaleza &uacute;nica de los g&eacute;neros monot{\&#39;ıpicos Mygalarachne [sic] Ausserer 1871 y Harpaxictis Simon 1892. La revisi&oacute;n 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&oacute;n a la subfamiliaTheraphhosinae y, por tanto, su actual ubicaci&oacute;n como &quot;incertae sedis&quot; es inadecuada y debe ser restaurada como g&eacute;nero v&aacute;lido. Aunque no es una sino-n{\&#39;ımia de Sericopelma, la identidad de Harpaxictis striatus es incierta, y a falta deotras caracter{\&#39;ısticas diagn&oacute;sticas proponemos considerarla como nomen dubium. Se discuten brevemente las posibles afinidades de Mygalarachne con otros g&eacute;neros v&aacute;lidos de Theraphosinae</p>
