Paralicella tenuipes CHEVREUX, 1908 and Paralicella caperesca SCHULENBERGER and BARNARD, 1976 are known as widely distributed deep-sea scavenging amphipods. Some recent studies based on genetic data indicated the presence of high intraspecific variation of P. caperesca suggesting it is a species complex. Based on published molecular data from the Pacific and Indian oceans and new material obtained from the North and South Atlantic, we integrated the knowledge on the intraspecific variation and species distribution of the two nominal taxa. The study included analysis of three genes (COI, 16S rRNA, 28S rRNA) and revealed the existence of a single Molecular Operational Taxonomic Unit (MOTU) within P. tenuipes and six different MOTUs forming P. caperesca. The distribution pattern of the recognized lineages varied with three (P. tenuipes, MOTU 1 and MOTU 5 of P. caperesca) being widely distributed. There was evidence of contemporary population connectivity expressed by the share of the same COI haplotypes by individuals from very distant localities. At the same time no signal of recent demographic changes was observed within the studied taxa. The time-calibrated phylogeny suggested the emergence of species to be at the time of Mesozoic/Cenozoic transition that may be associated with global changes of the ocean circulation and deep sea water cooling.

- Diego CARDEÑOSA uses DNA to track and monitor the shark fin trade. 99.8 percent of silky shark fins that were sampled originated from the Indo-Pacific Ocean. - This study emphasizes the need for increased monitoring in this region. - The long-term goal of CARDEÑOSA research is to provide information about where shark fins originate in order to better direct more concentrated shark conservation efforts and fisheries management.
