yeah, I've got 3 T. serrulatus. there's a publication out about how T. serrulatus is just a morph of T. stigmurus and although all populations in captivity and all populations near a human population density are said to be 100% female and parthenogenetic, there have been populations found where males have existed.
as far as I know, most T. stigmurus in the hobby are also parthenogenetic because it's easier to get a scorp that pops a brood every 4-10mo than it is to track down a male and breed them. needless to say, I'm willing to put my money where my mouth is on this one and say that you're going to be busy with these guys for the next few years.
here's the article from the Journal of Arachnology: http://www.americanarachnology.org/JoA_Congress/JoA_v27_n1/arac_27_01_0154.pdf
