Abstract:

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 géneros de tarántulas Neotropicales (Theraphosidae) indican la naturaleza única de los géneros monot{\'ıpicos Mygalarachne [sic] Ausserer 1871 y Harpaxictis Simon 1892. La revisión 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 adscripción a la subfamiliaTheraphhosinae y, por tanto, su actual ubicación como "incertae sedis" es inadecuada y debe ser restaurada como género válido. Aunque no es una sino-n{\'ımia de Sericopelma, la identidad de Harpaxictis striatus es incierta, y a falta deotras caracter{\'ısticas diagnósticas proponemos considerarla como nomen dubium. Se discuten brevemente las posibles afinidades de Mygalarachne con otros géneros válidos de Theraphosinae
