Two new silversides, Hypoatherina celebesensis and Hypoatherina macrophthalma, from the western Pacific (Atheriniformes: Atherinidae)
Two new atherinid fishes, Hypoatherina celebesensis and Hypoatherina macrophthalma, are described based on specimens collected from the tropical western Pacific. Both new species are closely similar to Hypoatherina ovalaua in general appearance and having the long and distally narrow premaxillary ascending process, but differ from the latter in lacking a tooth patch on palatines and having a longer head [27–31 % of standard length (SL) vs. 25–28 % SL]. Hypoatherina celebesensis can be distinguished from H. macrophthalma by having the midlateral band running downward anteriorly (vs. running straight), and a smaller upper jaw (9.3–11 % SL vs. 10–11 % SL) and eyes (9.6–11 % SL vs. 11–12 % SL). Hypoatherina celebesensis is known from Singapore, Indonesia (North Sulawesi and Timor), and Palau. Hypoatherina macrophthalma is known from Vietnam, Thailand (Gulf of Thailand), Papua New Guinea, and Micronesia.
