On the commercial shrimps of the Parapenaeopsis cornuta (Kishinouye 1900)" species group (Crustacea Decapoda Penaeidae)"

Abstract

Penaeid shrimps belonging to the Parapenaeopsis cornuta (Kishinouye, 1900) species group hold significant commercial value in the Indo-West Pacific, but their taxonomy has been problematic. A taxonomic revision of this group, supported by molecular genetic analysis using the barcoding gene COI, confirmed the validity of all four species within the group. Their distinguishing characteristics are redefined and illustrated, and a key for identifying the four species in the P. cornuta" group is provided."
