Some updates on my mated females.
P.muticus. Still nothing from the mated female. The male was passed on to my other female and lived with her for a bout a week. Then found bits and pieces of him in the enclosure, so hope he did his thing. Currently warming the mated female.
M.balfouri. My female that was mated with Scarab's male doesn't seem to be really fattening up.

Might try rehouse her away from the slings, as everytime I feed her, she seems to give her food away to the babies and ends up with nothing.
P.ornata. I have warmed and flooded her enclosure, so will see what she does. She has started webbing a bit, so might just get a sac out of her (Although the market is so flooded with these at the moment, they will probably go cheap if there is any success)
P.fasciata. Also warmed and flooded her. She has started heavily webbing, so looks good for a sac (Although these would probably also go for cheap if it were to be successful)
P.regalis. Rehoused, warmed and flooded her tonight. She has stopped eating, but not really webbing yet, so still waiting for her to decide what she is going to do.
P.striata. Also rehoused tonight. She is looking very fat, but not quite ready to warm and flood yet. Will give her another few weeks.
P.metallica. She has webbed herself up totally, hopefully preparing to drop. She has been warmed and flooded, but from Scarab's advice, these seem to be a bit on the slow side, so its a waiting game.
P.formosa. Also been warmed and flooded. And also started webbing. Will keep an eye on her.
P.subfusca. Looks like she won't be dropping a sac. She hasn't really picked up weight and will probably moult out. Atleast Scarab was successful, so some subfusca slings will hit the market.
P.rufilata. After numerous unsuccessful attempts with my female, I pretty much gave up mating them this year. Spoke to the owner of the male, and he agreed to let me cohabit them together. Had them together for a week and have now removed the male for the next person to use. Hopefully he got a mating in while living with her.
Now the good news.

Came home on Monday to my
P.miranda sitting on a nice sac.

The male was Hendriks. Will be pulling the sac in 2 weeks time and put up an official breeding report hopefully with some good news.
And then, when watering my spiders on Tuesday night I peeked into my
P.pederseni's enclosure and she is sitting on a huge sac. She was extremely fat before dropping, so hoping for a good number of slings if the sac is successful. Will pull her sac on the same day as the miranda, so will put a breeding report up for her as well then. Hopefully successful as I don't know of anyone else who has bred these in SA before.
