Leg 1 with 2 claws; chelicerae 2.5 to 3 times longer than wide; tiny to moderate-sized species...........................................................................................................Therobatinae....
Fixed chelicera! finger style-like or needle-like and straight, curved or undulate but not S-shaped; mesoventral groove present or absent; dorsal flagellum complex setae striate, ventral setae striate or plumose....
Fixed cheliceral finger with a mesoventral groove that varies from one or more indistinct creases to an elongate hollow or cup; small to moderate-sized species...............................
...............................................................................................................Eremochelis Roewer


"Small to large Therobatinae. Male fixed cheliceral finger with dorsomesal, mesal, or mesoventral groove. Dorsal setae of flagellum complex weakly to strongly striate, ventral setae weakly to strongly plumose. Plumose setae partially to completely cover mesal, mesoventral, or dorsomesal groove. Apical striate and apical plumose setae not especially modified on most species groups. However, in the branchi group the apical plumose seta is distinctly flattened. In the andreasana group both apical setae are strong and striate. The bilobatus species has both dorsal and ventral setae of complex plumose. Males, in addition to usual palpal clothing, often have femora, tibiae, and metatarsi provided below with one or two unequal rows of elongate spinelike setae. Female opercula extremely variable within genus but relatively consistent within species groups."
