Barnwell, F. H., and C. L. Thurman II. 1984. Taxonomy and biogeography of the fiddler crabs (Ocypodidae: Genus Uca) of the Atlantic and Gulf Coasts of eastern North America. Zoological Journal of the Linnean Society 81: 23–87.

A single specimen from the mouth of the Rio Grande River in extreme southern Texas was previously identified as this species (D. L. Felder, unpublished notes), but cannot be located among archived materials; this northern record thus remains questionable in the absence of a confirmable voucher; recent report of the warm-temperate Carolinean species U. pugnax (Smith, 1870) from Tabasco, Mexico, was noted by the authors (Álvarez et al. 2005) to be questionable, and may represent juvenile or variant materials of U. marguerita or U. rapax.
