How do you know you actually have Phrixotrichus scrofa? I have yet to see a hobby-labelled Phrixotrichus scrofa that is actually a Phrixotrichus.

umm. well...I don't. I have/had a Paraphysa scrofa, and I thought phrixotrichus is the new genus its in? I know (or atleast thought I knew) the new name also started with a P and just assumed that was it.

It's not Phrixotrichus due to it only having a single urticating patch. Some sort of Euathlus species is more than likely.
Maybe you are seeing something I am not, but in the picture linked to at the LLL Reptile site by sdsnybny I can only see one small lateral urticating hair patch. In the picture it is right above the patella and tibia segments of leg 4 (left side). In Euathlus, there is one large urticating hair patch on the dorso-posterior region of the abdomen. Kind of odd that there would be a single lateral urticating hair patch on one side but not on the other.

My spider just molted last night I'll get some better pics of mine when it hardens up, thanks for the input.

It is a tricky angle but the species posted have almost a heart shaped single urticating setae patch. Each "side of the heart" is split at the center of the abdomen. A true Phrixotrichus patch would be further down the side of the abdomen and more covered up by leg IV in that photograph. See an example here>>> Click me <<<This photo shows the characteristic twin lateral patches of Phrixotrichus better than the photos in the paper.
