“…The family Sinipercidae is a group of mainly freshwater fish found in Eastern Asia, with two Recent genera and 12 species (Fang & Chong 1932;Nelson et al 2016). Several fossil taxa (one extinct genus) of this family have been described from the Lower Miocene freshwater deposits of Korean Peninsula (Nam et al 2023) andChina (Chen et al 1999), Middle Miocene of Japan (Yabumoto 2020;Yabumoto & Uyeno 2009), and Middle Miocene marine deposits of Japan (Yabumoto & Uyeno 2000). The fossils under consideration share relatively high similarity with sinipercids, but Siniperca can be excluded due to the lack of support for the opercular spines, large spines at the ventral margin of the horizontal preopercular ramus (in some respects reminding preopercle of Lateolabrax -compare figs 6E and 6D in Katayama 1959), and a generally elongated neurocranium (Katayama 1959: fig.…”

The Indo-West Pacific is home to a diverse array of modern fish species, and the study of their fossils can provide valuable insights into the origins and evolution of this biodiversity. This report presents rare remains of five individuals of acropomatiform fish, including a semi-articulated skeleton, recovered from the Upper Kueichulin Formation (Lower Pliocene) in northern Taiwan. The fossils are preserved in the form of nodules discovered at the locality known for abundant marine crustaceans and echinoderms. These specimens can be assigned to the family Stereolepididae, based on morphology of the opercle with the presence of two spines, a preopercle characterized by serrations on the posterior margin and denticulations on the ventral margin, and a distinctive skull architecture. Differences in skull morphology distinguish these specimens from other species within the genus and thus are described as Stereolepis arcanum n. sp. Significantly, the species represents the oldest known record of the family globally and stands as the second known fossil representative. This discovery not only enhances our understanding of the palaeobiodiversity of fish fauna in the Indo-West Pacific during the Neogene, but also highlights the importance of further research efforts in this area.
