Leptuca musica, commonly known as the musical fiddler crab, is a species of fiddler crab native to Baja California and the Gulf of California in Mexico.[1]

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 10.5–11 mm 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]
