Discoplax hirtipes is a species of terrestrial crab.
Description and behaviour
D. hirtipes can be distinguished from other members of the genus Discoplax by the smooth and distinctly inflated carapace. It is also blue or blue-brown in colour, compared to purple or purple-brown in the remaining species.[2]
The breeding season for D. hirtipes lasts seven months, and females must migrate to the sea to release their larvae.[3]
Distribution
D. hirtipes has a wide distribution across the western Pacific Ocean.[4] It has been recorded from Japan, Taiwan, Palau, eastern Australia, Fiji and the Hawaiian Islands;[5] records from the Indian Ocean are now considered to belong to a related species, D. celeste.[4]
Taxonomic history
Discoplax hirtipes was originally described by James Dwight Dana under the name Cardisoma hirtipes. His description was published in 1851 based on material collected on the United States Exploring Expedition ("Wilkes expedition") in Fiji.[6] The type material has been lost, so a neotype from Fiji was designated in 2012.[4]
