Leptuca terpsichores, commonly known as the dancing fiddler crab, is a species of fiddler crab native to the eastern Pacific coast of the Americas, from Nicaragua to Peru.[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 L. musica.[1]
Description
The adult carapace is approximately 7 mm wide.[1] The carapace is grey in color and males may exhibit yellow dorsal markings.[1]
Similar species
Leptuca terpsichores is smaller than L. musica.[1] L. terpsichores has smaller tubercles on the outer manus and fewer tubercles along the anterior carapace.[1] The gape in the major cheliped is less serrate and the gape in the minor cheliped is slightly narrower.[1]
Habitat
The species can be found on bay shores with muddy sand substrate.[1]
