Wow Alonso! Right on! Bitten by the Scolo-bug huh? Glad to hear it. Take it easy with the subspinipes dude. You're gonna love it, especially feeding time.
I just scored 3 more of the Yellow Legged ssp. of the S. morsitans. A bud of mine who works at the local exotics shop owed me a few favors. In turn, I got the 3 African Yellow leg pedes (they had them labeled "Flag Tail Centipede"..I was like WTF?! I straightened them folks out though.) and the strange Mygalomorph I posted pics of in the "other arachnids" forum.
The only place I'm aware of right now is Glades Herp. They have a "Tanz. Yellow Legged Centipede" on their price list which is probably the S. morsitans ssp. I have never dealt with Glades personally though. They seem to have good prices on the bugs but the shipping cost is ridiculous imo. I'll check around to see if I can spot them elsewhere.
