Does anyone know the incubation period for Selenops eggs?

I have a female Selenops (flatty) that I caught in Phoenix, AZ back in June. Over the past month-and-a-half or so, she's made three egg sacs.

Has anyone ever raised/bred these spiders before? I'm wondering approximately how long it should take the eggs to hatch - if they're even fertile, that is! The mother was wild-caught, so I don't know if she had mated or not. I do know that she has not molted since I've had her.

Also, are Selenops one of the genera where the mother helps to tear open the egg sac when the babies are ready to emerge, or can they get out on their own?

Thank you!

Generally trues take about two-three weeks to hatch.

From what i've read, some selenops species guard their eggs, others just oviposit and leave.
