Comparative notes
The aedeagus of the new species bears a long and narrow ventral appendix. Other species of
Amanota
with a ventral appendix of the aedeagus are
A. perinetensis
(
Pace,
2006
) and
A. madecassa
(
Cameron
,
1944
), both from
Madagascar
, and
A. namibiensis
Pace,
1999
from
Tanzania
. In none of these species is the ventral appendix of the aedeagus as narrow and as long as in the new species.
