Abstract: |
|
| |
|
The examination of
specimens from various Neotropical tarantula genera (Theraphosidae)
indicated the unique nature of monotypic genera Mygalarachnae
Ausserer 1871 and Harpaxictis Simon 1892. Review of the both
holotypes leads us to argue that Mygalarachnae and Harpaxictis
should be removed from their current synonymy with Sericopelma
Ausserer 1875. The presence of type I and III urticating hairs on the
holotype specimen of Mygalarachnae firmly place it in the
subfamily Theraphosinae and we argue should be restored as a valid
genus, so that current placement of "incertae sedis" in 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 suggesteg as nomen dubium. Possible
affinities of Mygalarachne with other valid genera of
Theraphosinae are briefly discussed. |

Resumen: |
|
| |
|
El estudio de los
ejemplares de varios géneros de tarántulas Neotropicales (Theraphosidae)
indican la naturaleza única de los géneros monotípicos Mygalarachnae
Ausserer 1871 y Harpaxictis Simon 1892. La revisión de ambos
holotipos nos lleva a proponer que Mygalarachnae y Harpaxictis
no son sinonimias de Sericopelma Ausserer apoya claramente su
adscripción a la subfamilia Theraphosinae y, por tanto, su actual
ubicación como "incertae sedis" es inadecuada y debe ser restaurada como
género válido. Aunque no es una sinonímia de Sericopelma, la
identidad de Harpaxictis striatus es incierta, y a falta de otras
características diagnósticas proponemos considerarla como nomen dubium.
Se discuten brevemente las posibles afinidades de Mygalarachne
con otros géneros válidos de Theraphosinae. |
