ABSTRACT. New records of the spiny sand crab Lophomastix japonica (Duruflй, 1889) (Decapoda: Blepharipodidae) from the Russian coasts of the Sea of Japan are reported, based on collected exuvii and a living specimen. Additionally, the fossil remains of a carapace of Lophomastix sp., morphologically similar to modern L. japonica, was found in Upper Miocene formations of the western coast of Kamchatka (Sea of Okhotsk), which confirms that the genus was previously distributed much further north. The article presents barcoding data (fragment of COI mtDNA) for L. japonica for the first time, which will allow for a more detailed study of the phylogeography of this species in the future.
