Leptuca batuenta, commonly known as the beating fiddler crab, is a species of fiddler crab native to the tropical eastern Pacific, from El Salvador to northern Peru.[1]
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]
This crab is very small; carapace width is approximately 7 millimetres (0.28 in) in adult males and 5 millimetres (0.20 in) in adult females.[1] Both sexes have a pale brown to yellow carapace with some white marbling.[1] Individuals may have green eyestalks.[1]
The species can be found on open mudflats and among unshaded mangrove roots.[1] It prefers mud substrate.
