The new Indo-Pacific marine atherinid genus Doboatherina is established based on both morphological analysis and molecular-phylogenetic results. Furthermore, four species are described as new to science, and six species are redescribed as members of the new genus. “Atherina” valenciennei, “Atherina” woodwardi, Atherinomorus duodecimalis and Atherinomorus aetholepis are included in the new genus. The former two species had been excluded from the genus Hypoatherina by Sasaki and Kimura (2014) and the latter two species showed genetically close relationship with the former two. The new genus Doboatherina, belonging to the subfamily Atherinomorinae, is defined by the following combination of characters: ascending process of premaxilla somewhat short and blunt, its height 1.5 to 3.3 times the maximum width; premaxilla gradually tapering posteriorly, posterior lateral process small or absent; posterior upper margin of dentary usually with a process; upper posterior limb of dentary with pointed or sharply angular posterior tip; anterior preopercular ridge with a deep notch just above the corner; anus situated anterior to appressed pelvic-fin tip; dorsoventral height of exposed area in midlateral scale row wide, almost equal to the maximum height of the scale, and almost the same height as scales in just above or below midlateral row. The new genus is composed of the following ten species: D. aetholepis (Kimura, Iwatsuki and Yoshino 2002)—from the Gulf of Thailand, Philippines, Malaysia, Indonesia and Papua New Guinea; D. balabacensis (Seale 1910)—restricted to Philippines (neotype designated herein); D. bleekeri (Günther 1861)—occurring in northern Vietnam, China including Taiwan, southern Korea and Japan; D. duodecimalis (Valenciennes in Cuvier and Valenciennes 1835)—widely distributed in the Indo-West Pacific, from Comoro Is., Madagascar, Seychelles, Sri Lanka, Thailand (Andaman Sea), Indonesia, Papua New Guinea, and New Caledonia; D. iwatsukii sp. nov.—occurring in Thailand (both Andaman Sea and Gulf of Thailand) and Vietnam; D. magnidentata sp. nov.—occurring in Gulf of Thailand and Vietnam; D. salangensis sp. nov.—restricted to Thailand (Andaman Sea); D. valenciennei (Bleeker 1854)—occurring in Sri Lanka, Thailand (Gulf of Thailand and Andaman Sea), Vietnam, Malaysia (Sabah), Singapore, and Indonesia; D. woodwardi (Jordan and Starks 1901)—restricted Okinawa Prefecture, Japan; and D. yoshinoi sp. nov.—from Yaeyama Is., Japan and Panay I., Philippines.
