Thirteen species of theraphosid spiders ("tarantulas") are described as
new. Sphaerobothria hoffmani and Aphonopelma seemannz are redescribed and the
male 01" S. seemanni is described for the first time . It is argued that the genera
discussed here, which are traditionally placed in separa te subfamilies (Grammostolinae
and Isehnocolinae) should be grouped . Common features to these
genera are the shape of the bulb (distally atenuated and curved ventrally),
spermatheea divided in two portions by a deep noteh, and coxa 1 with anterior
side covered by conic spinules. The feature formerly used to separa te the two
groups is not consistent within genera.
Keys, diagnosis and explanations to figures are included in an English
Appendi x.
