ABSTRACT. A new infaunal shrimp of the genus Salmoneus Holthuis, 1955 (Crustacea: Decapoda: Alpheidae) is described from the burrows of the mangrove-dwelling alpheid shrimps Alpheus cf. euphrosyne de Man, 1897, Alpheus aff. lobidens De Haan, 1849 and upogebiid mud shrimp Wolffogebia phuketensis (Sakai, 1982) in a deep mangrove swamps of the Can Gio Mangrove Biosphere Reserve, South Vietnam. Salmoneus spiridonovi sp.n. appears morphologically close to the eastern Atlantic S. erasimorum Dworschak, Anker et Abed-Navandi, 2000, S. caboverdensis Dworschak, Anker et Abed-Navandi, 2000, the western Atlantic S. degravei Anker, 2010, and the Indo-West Pacific S. seticheles Anker, 2003, S. brucei Komai, 2009, S. yoyo Anker, Firdaus et Pratama, 2014 and S. durisi Anker, 2019, which are characterized by both pereiopods I (chelipeds) being enlarged, subequal in size, but asymmetrical in the shape, clearly separating them from other species in the genus. Moreover, the new species is the first representative of the genus Salmoneus recorded as an infaunal associate of upogebiid burrows.
