Caraboctonus Pocock, 1893 . Composition. This new family is established here. It includes two subfamilies: Caraboctoninae and Hadrurinae . Tribes are not recognized. Distribution . North America, South America. Biogeographic history . The family Caraboctonidae has a disjunct range, with subfamily Caraboctoninae in South America (with two disjunct genera), and subfamily Hadrurinae with disjunct range in Mexico and North America. Diagnosis . Synapomorphies. Chelal trichobothrium Et 5 positioned on fixed finger; neobothriotaxy present on external surface of patella; dorsal edge of cheliceral movable finger with two subdistal denticles; leg coxae IV elongated; lateral carinae partially present on metasomal segment IV; chela with “10-carinae” configuration. Important Symplesiomorphies. Ventral edge of cheliceral movable finger with one large denticle; ventral surface of leg tarsus with median row of spinule clusters; stigma oval in shape; chelal trichobothrial series db–dt and eb–et found on distal half of finger; patellar ventral trichobothrium v 3 found on external surface.
