There is very little reference material of spermathecae for this species available, so it makes it difficult. I would say the images with a single, small lobe are from a male (like this one), but the ones where there appears to be 2 small humps side by side are possible females - like this:
Thanks for the reply.
This particular exuvium has two humps too.
When stretching the exuvium, theese two "humps" and central flap form some sort of triangle. Another exuvium shows central structure and two tiny tubes aside. Not sure, if these are assesory organs.
Ofc, i will continue making photos. I have 9 slings at the moment.
If situation becomes clear - I will post a little thread with comparison and development stages.
