Remarks. As previously shown by Ng et al. (2018), the genus Eurycarcinus is represented by three species, E. integrifrons de Man, 1879 , E. orientalis A. Milne-Edwards, 1867 , and E. natalensis ( Krauss 1843) . In the past, E. integrifrons and E. orientalis were thought to be synonymous, but in fact they belong to two distinct species ( Apel 2001; Ng et al. 2018). Eurycarcinus integrifrons was limited to the northwestern Indian Ocean: Gulf of Aden, Arabian Sea, Persian Gulf, Gulf of Oman, Pakistan and western India ( Apel 2001; Naderloo & Türkay 2012; Naderloo 2017). Canzcan et al. (2010) was the first to report this species from the eastern Mediterranean in Turkey and suggested that it may have entered the region through ballast water. Abdelsalam et al. (2018) recently reported the species from an Egyptian port in southern Turkey. Trivedi et al. (2021) conducted a comprehensive study on the Indian species of Eurycarcinus .
