[Re:] Cryptic Species Discussion

[Thomas Schlemmermeyer]

Allopatric speciation may be inflicted by geological events. I still
do not know the history of the region, but it seems there is a lot of
volcanism going on.

Maybe one population with the hemipenis characters in question was
geographically isolated and than these genes were fixed (genetic drift) without
that there even was selection, or selection acted in the past and was then
fixed by drift.
