Pérez Farfante & Kensley (1997) revised the genus Penaeus, splitting it into several genera, the status of which have been subject to considerable controversy since. We have elected here to maintain this genus with full generic status, following De Grave & Fransen, 2011. At this stage, three names for this species (Penaeus plebejus, Penaeus (Melicertus) plebejus and Melicertus plebejus) will be encountered in the literature, with no real consensus on which is more valid.
