The pilumnid crab Pilumnopeus convexus (Maccagno, 1936), native to the Arabian Sea and western Indian Ocean, has been discovered among intertidal fouling communities along shores of Hong Kong. The species was first discovered in 2011 and is believed to have become established by around 2016. Material from local sites was compared with specimens from Iran and Pakistan, and the identification was supported by molecular analyses using mtDNA COI gene sequences. This species is not yet known from East and Southeast Asia, and was probably transported to Hong Kong by international maritime shipping, likely in the ballast water or on the hulls of ships, and subsequently survived as a non-indigenous species (NIS). This represents the first case of west-to-east invasion of brachyuran crabs from the Indian Ocean reaching sub-tropical East Asia. Past studies on the local intertidal fauna, and documentations of NIS, are briefly discussed. [ABSTRACT FROM AUTHOR]
