[Ammotrechinae whose 2nd and 3 Tarsus each bear 1.2.2.1 ventral spines and whose 4th tarsus bears 2.2/2/2.1 ventral spines (Fig. 335, b, h).  Immovable finger of chelicerae with 2 anterior teeth in front of the median tooth and movable finger with 1 medial cheek tooth next to the main tooth (Fig. 337, d-f).]
