Based
on recently collected material and records in the literature, 14
species of fiddler crabs (Crustacea: Ocypodidae: Gelasiminae) are
reported from Vietnam. DNA barcoding analyses using the mitochondrial
gene COI (cytochrome c oxidase
subunit I) was performed to identify examined materials and their
precise distributional range. Thirteen species-level taxa are
identified and, with the exception of Galsimus
borealis and G. vocans,
have minimum interspcific divergences of at least 7.27%. The identified
species include seven species of Tubuca
Bott, 1973, three of Austruca
Bott, 1973 and three of Gelasimus
Latreille, 1817, and one Paraleptuca
Bott, 1973. Two new records of Vietnam are herein reported: Tubuca rhizophorae and T. dussumieri. The southernmost
distribution limits of East Asian G.
borealis, T. acuta and
T. arcuata
are in northern Vietnam, A. lactea
in central Vietnam, whereas northernmost limit of Southeast Asian T. rhizophorae and T. forcipata in southern Vietnam. A
dichotomous key to identify the 14 Vietnamese species is provided.
Key words: Fiddler crabs, New
records, Austruca, Gelasimus, Paraleptuca, Tubuca, Mitochondrial cytochrome c oxidase subunit I (COI), Barcodes.
