Abstract
Two new atherinid fishes, Hypoatherina golanii and Hypoatherina lunata, are described based on specimens collected from the wide range of the Indo-West Pacific. The former species is known from the Red Sea and was confused with Hypoatherina barnesi because it has a somewhat wide midlateral band and overlapping meristic counts. Hypoatherina golanii is distinguished from its congeners by the midlateral scales with an indented posterior margin, posterior margin of anterior predorsal scales with a spatular outgrowth, posterior margin of axillary scales without a distinct projection, and posterior end of maxilla not slanted downward. Hypoatherina lunata is distributed in the waters of southern Japan (Okinawa and Kagoshima prefectures) and Indonesia (North Sulawesi, Maluku, and Papua), but was confused with Hypoatherina woodwardi. Hypoatherina lunata is distinguished from its congeners in having a distinct crescent marking in front of the eye and the anus usually situated anterior to the tip of the pelvic fin.
