Vaejovis spinigerus sexing

[photographer11]

I purchased 3 of these guys at NARBC last weekend and was told one of them was a male for sure. How can I tell which is a male. It appears to me as if I may have a gravid female as well.

Well we need pictures of their pectines for starters, and threads involving Paravaejovis spinigerus, don't seem to get much attention...

I have both a male and a female Spinigerus.
Look at their underside. Males generally have Book Lungs that extend slightly past the sides of their body. Females are generally shorter.
Hope this helps.

And def post pics. That'll help for sure.
