Identification
"Similar in appearance to sac spiders, and used to be placed in the same family. They differ in that they have two rows of club-shaped hairs on the bottoms of their feet, and their tracheal spiracle is located well in front of the spinnerets, unlike most spiders which have their tracheal opening right in front of the spinnerets."(1)
