Colombian giant spermetheca

[RazorRipley]

Heres a question for you advanced hobbyists....
Is a sub-adult (5 inches) robustums spermetheca visible to the naked eye? And does anyone happen to know what the spermetheca for this species look like???
Thanks

if it is not visible to the eye.. how can it be 5 inches?

At 5 inches, spermatheca will be visible to the naked eye. It's been a while since I last kept any Megaphobema, and I've cleaned house in the exuvia dept., so I cannot clue you in to the shape of spermatheca. It will be unmistakeable though.

The spermatheca from Megaphobema robustum is fused and has I kind of dome shape to it.It looks a little like the pic of the Haplopelma sp "longipedum" in this link Click Here ,but in Megaphobema robustum the spermatheca has a more higher dome!
Not sure if this is of any help.
