Taxonomy
Previously a member of the genus Uca, the species was transferred in 2016 to the genus Leptuca when Leptuca was promoted from subgenus to genus level.[2][3] At one time, the species was considered a subspecies of the same species with L. terpsichores.[1]
Description
The adult carapace is usually around 10.5-11mm wide and is cylindrical.[1] The minor cheliped is small in both sexes and has a wide gape.[1]
Similar species
L. musica is somewhat larger than L. terpsichores.[1] The tubercles on the outer manus are larger and they are more numerous along the anterior carapace.[1] The gape in the major cheliped is more serrate and the gape in the minor cheliped is slightly wider.[1]
