Abstract: |
|
| |
|
The holotype of
Polyspinosa schulzei, type species of the genus Polyspinosa,
(Eumenophorinae) is revised. It presents spiniform setae on the coxae of
legs and palpi and stridulatory setae on the coxa of leg I. The presence
of this character and the information that the specimen was African were
probably the reasons for including it in the Eumenophorinae. However,
the discovery of type-IV urticating hair in the holotype indicates that
the species should belong to the New World Theraphosinae, since the
presence of this type of urticating hair is a synapomorphy of this
subfamily's genera. The presence of stridulatory setae as well as the
type of urticating hair found and the shape of the spermathecae are
characters shared by species of the genus Grammostola
(Theraphosinae). Thus, Grammostola schulzei (Schmidt, 1994) comb.
n. is established and the genus Polyspinosa Schmidt, 1999 is
considered a junior synonym of Grammostola Simon, 1892 syn. n. |

Resumen: |
|
| |
|
Se ha revisado el
holotipo de Polyspinosa shulzei, especie-tipo del género Polyspinosa
(Eumenophorinae). El espécimen presenta cerdas espiniformes en las coxas
de patas y pedipalpos, y cerdas estridulatorias en la coxa de la pata I.
La presencia de estas cerdas y el dato de que el espécimen era africano
fueron probablemente los motivos para su inclusión en los
Eumenophorinae. Sin embargo, la presencia de pelos urticantes del tipo
IV en el holotipo, que corresponde a una sinapomorfía de los géneros de
Theraphosinae, indica que se trata de una especie del Nuevo Mundo. Las
cerdas estridulatorias, el tipo de pelo urticante encontrado y la
morfología de la espermateca son característicos del género
Grammostola (Theraphosinae). Así, la especie se transfiere a
Grammostola schulzei comb. n., y el género Polyspinosa se
considera sinónimo posterior de Grammostola syn. n. |
