The
taxonomy of the gecarcinid land crab Tuerkayana
rotundum (Quoy & Gaimard, 1824) is revised. The taxon, the
type species of the genus, occurs from the western Indian Ocean to the
western Pacific, and varies substantially in colour and various
morphological features, but the male first gonopod structure is
constant and the extensive genetic data from mitochondrial 16S rDNA,
cytochrome c oxidase subunit 1 and control region markers confirms the
recognition of one wide-ranging species. Specimens from Tuamotu in
French Polynesia and Pitcairn Island, however, differ in having a
smoother and slightly more swollen carapace, and significantly, the
male first gonopod structure is distinctly different. The genetic data
also supports their differentiation. As such, this material is here
recognised as a new species, Tuerkayana
latens n. sp.
Key words: Land crabs, Gecarcinidae,
