Well im a little late, but for what its worth, I have two almost certainly gravid A anax with butts just like that..right down to the huge bald patch and pale, non premolt skin. Don't know if that means anything, my porteri didnt have the patch when she made a sac..it may just be coincidence.

2 of the 3 females look the same, huge butts, bald spots but pale. The 3rd female didnt put on weight and eventually molted so im hoping both of these are gravid.

Good luck man. Im just getting into breeding. I have two anax and one Lp that are hopefully going to give me sacs. My only other experience is a porteri that I got 240 slings from and she ate the other sac. And the male, poor bastard..lots of baby scorps though, those things are like bunnies :)

Here is some brief breeding notes from when I bred these earlier this year which may help you.

Bought a breeding pair from TSS around the start of October, mated them at the end of October once the male had made a sperm web. Kept the female at around 23c on fairly moist substrate throughout October. Then over the next few months let the substrate slowly dry out and the temperature drop down to 20c for a month then 17c. Female was fed about 6 adult crickets a month during this time.
Mid January I raised the temperature to 20c then at the start of February I soaked the substrate and raised the temperature up to 23c with occasional peaks of 26c during the day. Female was fed 3 or 4 adult crickets during this period.
Around the 15th of February the female began to start digging up substrate a bit and on the 21st completely dug out the substrate in her hide and packed it against the far wall of her tank. On the morning of the 26th she started laying strands of web around her hide and later on in the afternoon I caught her kicking hair off the sides of her abdomen onto this so I knew a sac was imminent. She didn't start webbing again until late that night and when I checked on her the next day she had finished her sac.
I pulled the sac after 23 days (21st March) and artificially incubated using a hammock style incubator at around 25c. The sac was full of nymph stage I (eggs with legs) at this point.
33 days after sac construction (31st March) the nymph I started to moult into nymph II.
70 days after sac construction (7th May) the nymph II started to moult into spiderlings.
568 spiderlings in total give or take a few.
