Resumen:
We report the occurrence of the invasive amphipod Monocorophiumacherusicumin Mar del Plata port, Argentina, usingmorphological andmolecular analysis and estimatedmean abundance to detectmonthlyvariations of this population. We compared M. acherusicummorphology with that of M. insidiosum and Crassicorophium bonelli,the two most similar locally occurring species, to establish thediagnostic characteristics for the correct identification of them;moreover, we provide some taxonomic notes about otherscorophiids regionally distributed. M. acherusicum were collected in asubtidal biofouling community and its mean abundance wasmaximum in summer. In the molecular analysis, the maximumlikelihoodtree showed that specimens from Mar del Plata wereclustered with M. acherusicum specimens from GenBank andBoldsystems. We support and confirm the species identity in Mardel Plata port using DNA barcoding and with taxonomic methods.
