Relationships among populations (southeast Atlantic and northern Gulf coast, USA) of a ubiquitous, estuarine, harpacticoid copepod (Microarthridion littorale Poppe) were estimated using sequence data from two loci: one mitochondrial [cytochrome b (Cyt b)] and one nuclear [®rst internal transcribed spacer of ribosomal DNA (ITS-1)]. Copepods were collected from seven estuaries in 1997/98. Allelic phylogenies based on both genes were generally concordant, and suggested that M. littorale populations are structured over large geographic scales (hundreds of kilometers). Three wellsupported groups were found in both gene trees comprising clades of alleles sampled from South Carolina, Florida, and Louisiana. Alleles from the Savannah, Georgia sample formed a monophyletic group using the Cyt b data, but this clade was not distinguishable with comparable ITS-1 data. A single specimen from Louisiana was classi®ed in di€erent clades depending on the locus assayed.
