Diagnosis. All four teeth on fixed finger of chelicera are distinct (i.e., the median and basal teeth do not form a bicusp). The movable finger has one subdistal and one basal tooth on the external margin; external distal tooth smaller than the internal distal; internal margin with distinct serration or a row of small teeth. Trichobothrial pattern is of Type B. All species possess the fundamental number and pattern of Type B (Vachon 1974). The coxapophyses have broadly expanded anterior lobes. The sternum is subpentagonal. The legs lack tibial spurs, but both prolateral and retrolateral pedal spurs are present. Tarsi bear two rows of ventral setae and a median row of spinules. The telson is without a subaculear tubercle.
