For the sake of an old argument I just recently had my male and female p.subfuscas that were from the same egg sac molt on the exact same day. And what is strikingly odd and funny somewhat proving my theory. Is that my male just molted into a confirmed female "lowland" while my confirmed female "highland" stayed the same.... I contacted my close friend immediately after finding out and we are contacting the original seller who sold them to him at one inch to make completely sure they are from the same egg sac. They are both 5" now and extremely gorgeous and without a single doubt by all characteristics and identifications highland and lowland females. So my theory of believing they are possible somewhat colormorphs from one another do to the regions they are from has been even more strengthened. I am now in 99% belief these are the exact same species. I have also compared many male and females of both species just in case. And they are without a doubt females of the variations in the species.
