Hi Hartmut,
I would like to have these references..
Russell's thesis was where I got the idea. Then Joger's studies more or less
concluded that both Phelsuma and Lygodactylus were very far away from
Pachydactylus, which is not the same as that they were related..
But, later articles by Kluge f.i. had them in separate groups (based on
some arm of the guittural cartilage or something) Pasteur had a nice theory
about how Lygodactylus conquisted Madagascar... and my paper was basically
trying to refute these two hypotheses.. I found an amazing lot of
'synapomorphies' between the Lygodactylus and Phelsuma, but given that they
are sister-groups, Domerguella should be raised to generic status and there
should be raised another genus for the mutabilis-breviceps-ocellatus-group.
All to much taxonomic adoo for me at that time..I should have studied
another thousand pickled geckoes..
Given that the classification within the Gekkonidae is still very unclear, a
lot more should have to be explained as well, but Ailuronyx and Homopholis
in my opinion were from another group and Uroplatus is a totally different
clade.. I had only one Ebenavia to count scales on, so I could not conclude
anything about that genus..
I could go into this matter much deeper if someone wishes to discuss this,
but first I will goon holyday for a week. Something very ungekkolike as
freestyle skiing..

Well, someone will have to start breeding them somewhere, too - so why not
you? By the way, should you happen to know someone who will attend the
International Gecko-Keepers Meeting in Germany in June, then you MIGHT be
able to get some from me ... ;-) At least last year we had some North
American
guests as well ... so, anyone interested?

Well, their parasite loads seem to differ from batch to batch - perhaps this
is
due to the different conditions in the importer´s cages ... after all, once
a
cage has been infested, it will probably distribute it´s load to all species
who
are put into it, even if they were "clean" before ... :-(
Best would be to do fecals and then choose appropriate treatment, but
remember that some parasites will only kill weakened animals - sometimes
it seems better to wait until the animals have come over the stress of catch
and transport, and then treat them - treating them right away will give some
animals just the little more push needed to finally kill them.

I thought that they were sistergroups was already common fact? In the book
"Faszinierende Taggeckos" (Phelsuma) the Authors mention studies done by
RUSSELL (1972) and JOGER (1985), in which (based on different aspects)
they classify an afro-madagassan group with Phelsuma, Ailuronyx, Homopholis,
Microscallabotes and Lygodactylus in it ... and concluding that they
probably
had common ancestors. Uroplatus und Ebenavia have similarities, but don´t
seem to fit completely. Later studies (KLUGE, BAUER, JOGER, NUSSBAUM)
try to bring more light into this topic, but all seem to agree that
Lygodactylus
and Phelsuma are sistergroups and share common ancestors ... .

I could only try to translate what I found in the book I mentioned above -
if
you
really want to read this stuff in detail, I could quote the
literature-titles
given in
the book for you ... ?
