Diagnosis

Males own a palpal bulb with two prolateral keels, with the tip curved retrolaterally. The tibial apophyses has retrolateral spines and a spine on the retrolateral branch which almost reached the apex. And a urticating patch in the center of the opisthosoma, which own mainly type 3 and 4 urticating hairs. Females also can be distinguished by two 4 sided spermathecal receptacles, with sphere like chambers.^[4]
