Described by Rick west of Canada and Steve Nunn of Australia in 2010 where it was originally placed in the Coremiocnemis genus. It was later transferred in 2012 when the genus Psednocnemis was created. This spider was bred in captivity for years before it was described though while usually just being referred too as Malaysian blue femur. Not a large spider, this obgalte burrow gets only about 4 inches as adults. Super beautiful royal blue color that almost shines after a molt.
