Paradiastylis Calman, 1904

Type species. Paradiastylis brachyura Calman, 1904 .

Diagnosis. Female. Without exopod on maxilliped 3. Adult male. Bases of pereopods 1–4 greatly expanded, bases of exopods on pereopods 1–4 expanded.

Remarks. Paradiastylis and Dimorphostylis can only be reliably separated by the maxilliped 3 exopod, absent in Paradiastylis females and present in Dimorphostylis females. If females are not present, it may not be possible to differentiate between the two genera.
