Type genus: Paragoniosoma gen. nov. Subfamily monotypic.

Diagnosis. Gonyleptidae of large body. Two pairs of ozopores. Four areas on opisthosomal scutum with spots of thick serous layer. Pedipalps long and robust with long and strong setae on tibia and tarsus. Long legs. Coxa IV with a strong ectal apophysis. Tarsal process large. Penis with a large ventral plate with concave distal margin, two rows of five macrosetae A and two large B and glans with a ventral process with flabellum and a dorsal process. It differs from Goniosomatinae by having four areas on dorsal scutum with transversal groove II almost straight, ectal apophysis of coxa IV longitudinal, presence of serous layer (instead of dry-mark) on dorsal scutum, absence of dry-mark on coxa IV, absence of ventral armature on pedipalp femur, and penis with two rows of five macrosetae A and large B.
