The family Aristeidae (Wood-Manson, 1891) is part of the order Decapoda. It is widely distributed around the world and lives in deep waters, especially in muddy bottoms. In this family there are two species, Aristeus antennatus and Aristaeomorpha foliacea, which are currently the most economically important and most widely studied. The genetic studies of these two species have made it possible to make recommendations for their fisheries management, avoiding overexploitation and promoting their conservation. However, the rest of the species in this family have not been so genetically studied. Therefore, the aim of this study is to carry out a review of the genetic studies of shrimps belonging to the family Aristeidae except A. antennatus and A. foliacea. To carry out this study, a bibliographic search was carried out in two databases, WOS and SCOPUS, entering different key terms with various Boolean tools. The result of the search was a total of 13 articles, of which only 5 were selected, as they were the ones that dealt with the subject. Once selected, they were related and grouped based on the genera that are part of the Aristeidae family. It has been observed that of all the genus that make up the family Aristeidae, the genus Aristeus and the species Aristeus alcocki, are the ones with the most genetic studies, both phylogenetic and population. Despite this, at present it has not yet been possible to establish a clear phylogenetic relationship within the genus Aristeus because not all its species have been used with the same molecular markers. Only a single genetic study has been detected for the genera Cerataspis, Hemipenaeus and Aristaeopsis, and none for the other genera Aristaeomorpha, Austropenaeus, Hepomadus, Parahepomadus and Pseudoaristeus. Therefore, it is recommended that of all these genera and in particular of those for which there is no study, to sample the different geographical areas not analyzed to date and to prepare future molecular analyzes to expand their information. With regard to population studies, it has only been carried out for A. alcocki, therefore, for the rest of the species of this family, it is proposed to direct efforts to carry out these studies through microsatellites and SNPs. Currently, most species of the Aristeidae family have one or more sequenced genes, which shows that there is interest in obtaining more information about this little-analyzed group of shrimps
