“…Seven Uranoscopidae species have been reported in China, namely Uranoscopus chinensis, U. tosae, U. oligolepis, U. japonicus, U. bicinctus, Xenocephalus elongatus, and Ichthyscopus lebeck (Chen and Zhang, 2016;Liu et al, 2016a). However, recent studies have raised controversies regarding the classification and identification of Uranoscopidae species (Vilasri et al, 2019;Prokofiev, 2021). Notably, there is a lack of specialized scholars conducting comprehensive studies on Uranoscopidae, particularly in the realm of molecular phylogeny.…”

The construction of high-quality genomes is fundamental for molecular studies of species. Currently, there are no published genome sequences within the Uranoscopidae family, and research on the genomic characteristics of this family is lacking. In this study, genomic analyses of seven species from the Uranoscopidae family which captured from the southeastern coast of China were conducted using next-generation sequencing technology. The results revealed that the genomic characteristics of the seven species are relatively similar. The genome sizes of the seven Uranoscopidae species ranged from 536.00 Mb to 652.49 Mb, with repeat sequence proportions between 20.09% and 36.64%, and heterozygosity levels ranging from 0.41% to 0.88%. The assembled draft genomes exhibited GC contents of these species ranging from approximately 42.14% to 43.53%. Furthermore, the mitochondrial sequences for the seven species were assembled, with sizes ranging from 14,966 to 18,446 bp. The evolutionary relationships between different species were depicted through the mapping of conserved genes, whole-genome variances and mitochondrial genome sequences. Besides, the historical effective population sizes of all species experienced rapid expansion after the Last Interglacial Period, with three species undergoing bottleneck effects. In conclusion, this study provides a reference for the subsequent construction of high-quality genomes for species within the Uranoscopidae family and offers a rich data resource for further evolutionary research.

Knowledge of Neogene fish diversity in Taiwan is extremely limited. In this paper, we present a collection of 1716 fish otoliths recovered from the late Miocene Tapu Formation. The abundance and density of otoliths vary across the sites. Although the preservation of samples is considerably limited, our sample coverage is sufficient and reveals the presence of at least 34 otolith-based taxa belonging to 13 families. Four new species are introduced: Larimichthys koae sp. nov., Nibea chaoi sp. nov., Taosciaena jiangi sp. nov., and T. hui sp. nov. Among the earliest fossil records, this collection features a remarkable abundance of Larimichthys spp. The assemblage is dominated by otoliths of Sciaenidae, Gobiidae and Soleidae, and it is indicative of a coastal shallow-water palaeoenvironment with muddy to sandy bottoms, perhaps adjacent to a river mouth. We hypothesise that the differences in the taxonomic composition between the fossil assemblage and modern fauna are mainly chronological and evolutionary, and only a moderate turnover of certain lineages has occurred since the Miocene. Our study provides a unique 'window' to a rarely visited fossil fish community that exclusively documented by fossil otolith data, and reveals a past coastal fish diversity that otherwise could not be recognised.
