New subgeneric names for the most commercially important shrimp genus Penaeus Fabricius, 1798 (Crustacea, Decapoda, Penaeidae)

Although a recent comprehensive molecular phylogenetic study on Penaeus Fabricius, 1798 reinstated a single genus for these economically important shrimps, several clades in the molecular phylogenetic tree do not have formal names. Subgeneric names are given herein to five of these clades if Penaeus is to be split. A key to the subgenera in Penaeus is also provided.

Automated summary

A recent study on Penaeus Fabricius, 1798 suggests that all economically important shrimps should belong to a single genus, but there are some clades in the molecular phylogenetic tree that lack formal names. This study proposes subgeneric names for five of these clades in case Penaeus is split. A key to the subgenera in Penaeus is provided.
