On two allied species of the genus Diastylis from southern South America: D. granulata Zimmer, 1921 and D. argentata Calman, 1912 (Crustacea: Cumacea: Diastylidae)
The adult male and female of Diastylis granulata Zimmer, 1921 are herein described on the basis of specimens collected near its type locality. This species was previously known from a single subadult male collected south of the Río de la Plata mouth (Argentina) during the Swedish Eugenie Expedition...
