MADAGASCAR PHYXELIDIDAE   :

GLOBAL RELATIONSHIPS

Phyxelidids were formerly considered as an example of multiple (perhaps three) clades that show independent relationships between Madagascar and tropical east Africa ( Griswold, 2000). The results of our molecular phylogenetic analysis, corroborated by a morphological synapomorphy, i.e. the rotation of the clasping spine on male metatarsus I from retrolateral to prolateral ( Figs 1 View Figure 1 , 9D View Figure 9 ), support the monophyly of the Malagasy phyxelidids, which are probably related to phyxelidids from eastern or southern Africa. This in turn implies a single invasion of Madagascar, not multiple invasions. Other spider examples of multiple Africa– Madagascar relationships, i.e. Cyatholipidae   and Zorocratidae ( Griswold, 2000)   , also deserve re-examination.
