Nine
species of fiddler crabs (Crustacea: Ocypodidae: Gelasiminae) are known
from the Arabian Sea and adjacent waters (Red Sea, Gulf of Aden, Gulf
of Oman and Arabian/Persian Gulf): five species of Austruca, one Cranuca, two Gelasimus and one Tubuca. COI
sequence data match morphological species boundaries and shows high
connectivity within each. The fauna is highly endemic, with three
species of Austruca (A. albimana, A. iranica and A. sindensis) confined
to this region, and four other
species are restricted to the Indian Ocean. Austruca albimana and A. iranica speciated locally and
now have narrowly overlapping ranges in Oman. Our results confirm the
westernmost distributions of Austruca
annulipes and Tubuca alcocki
are Pakistan and the Red Sea, respectively. A key for the nine species
is also provided to help identification.
Key words: Fiddler crabs, Austruca, Cranuca, Gelasimus, Tubuca, Mitochondrial cytochrome c oxidase subunit I (COI), Barcodes.
