Because fleas are such a highly
derived group, phylogenetic relationships
among the species have never been established
using formal character analysis. We are
sequencing multiple molecular markers
for a wide range of flea taxa, and beginning
to compile a morphological matrix for
phylogenetic analysis. In addition, we
have established a flea website for the
photo documentation of flea species, and
the dissemination of flea related data.
Preliminary results suggest that the majority
of flea families are paraphyletic, and
that the group is going to require major
