A big pet peeve of mine is that so few of the photos in this album are ever updated with moult confirmations. It makes trying to compare to other photos almost useless. I really wish people would provide updates.
I checked the exuvia and I didn't see anything resembling a uterus externus, or spermathecae, so I have already marked this tyke as male. I thought I would try to get a ventral shot to double check and now I am not too sure.
I've got two, and originally I was thinking they were both female, but that looks quite a bit like epiandrous fusillae to me. I figured I would get some other opinions. I thought I saw spermathecae in the molt, but it may have just been a tear
Molt confirmed female. She always looked male ventrally until this most recent molt, but it's obvious she's female now that she's reached the 3" mark. So for people with smaller versicolor slings attempting to sex them ventrally, it might be best to wait until around 3" to determine sex
