“…Records of misidentification could lead to erroneous information on species distribution data and therefore mislead our understanding of the biodiversity pattern and evolution of the species (Hung et al, 2017). In Chelidoperca, for instance, the name C. "margaritifera" has repeatedly appeared in the literature along with regional species records or checklists (e.g., in Katayama, 1984;Yamada et al, 2007;Fricke et al, 2011;Senou, 2013).…”

“…Total genomic DNA was extracted from the tissue samples of 47 Chelidoperca individuals and one individual from an outgroup taxon, Centropristis philadelphica, using an automatic extractor: LabTurbo 48 Compact System and LGD 480-500 kits (Taigene Biosciences Corp., Taipei) following the manufacturer's protocol. One mitochondrial protein-coding gene (cytochrome oxidase c subunit I [COI]) and one nuclear protein-coding gene (recombination activating protein 1 [RAG1]) were used as genetic markers in this study for their ability to provide species delimitation (Ward et al, 2005;Hung et al, 2017;Lo et al, 2017) and phylogenetic information (López et al, 2004;Chen et al, 2014;Lo et al, 2015Lo et al, , 2017Hung et al, 2017), respectively. Protocols for collecting molecular data followed Ward et al (2005) and the previous study of Lo et al (2015).…”

“…Other criteria applied to evaluate the validity of inferred species included an evaluation of the pairwise genetic distances of the taxa, species monophyly found in gene trees, and the results of morphological comparisons. Finally, as suggested in Kekkonen and Hebert (2014) and applied by Lo et al (2017) and Hung et al (2017), resulting allopatric sister OTUs from the COI species delimitation analyses were treated as a single OTU rather than separating them into multiple OTUs when no other evidence suggested the reproductive isolation of sister putative species or OTUs.…”

“…Therefore, we defined three western Pacific geographic regions based on the levels of regional endemicity of marine species (notably in Chelidoperca spp. ), ocean currents, and other physical barriers (see: Hung et al, 2017): (1) northwestern Pacific (NWP; including East China Sea, Philippines, Southern Japan, South China Sea, and Taiwan); (2) tropical West Pacific (TWP; including West Papua and the Bismarck Sea off northern Papua New Guinea); and (3) tropical Australia and Coral Sea (TA+CS; including New Caledonia, Vanuatu, and the Solomon Sea). The designation of sympatry or allopatry of inferred sister OTUs was based on these defined regions.…”

“…As a paper by MM and AO describing this new species was already in preparation, all four present co-authors agreed to separately describe the other species. The objective of the present paper is thus to use an integrated approach in systematics (see: Dayrat, 2005;Hung et al, 2017;Lo et al, 2017;Puillandre et al, 2017) to explore the phylogeny and species diversity of the Chelidoperca, especially those occurring in the West Pacific. Our results reveal an even greater species diversity of the genus than previously thought and extend the distribution range of two already known species, C. stella and C. tosaensis.…”

With 11 species, the genus Chelidoperca is a small group of teleost fishes belonging to the Serranidae. They are bottom-dwelling fishes living on continental shelves/slopes in offshore areas or on remote seamounts/banks at depths ranging from around 40-400 m mostly in the tropical Indo-West Pacific. Over the past few years, efforts have been made to resolve the taxonomy of Chelidoperca, and subsequently four new species were described. However, these recent advances were made with a traditional approach (i.e., morphology) and limited examinable materials, usually preserved specimens, from ichthyological collections. Further investigations are still needed to address the gaps in our knowledge about their diversity, phylogeny, and biogeography. In this study, we collected 65 new samples, mainly during eight biodiversity expeditions carried out between 2007 and 2016 in the West Pacific under the Tropical Deep-Sea Benthos program. Specimens were photographed after collection to record fresh color patterns, which are essential for species diagnosis. Our analytical approach includes state-of-the-art DNA-based methods for species delimitation. The combined evidence from both molecular and morphological examinations, as well as other information such as geography, is used to test species validity. This reveals 15 species, including six new ones. We formally describe herein C. leucostigmata sp. nov., C. microdon sp. nov., and C. barazeri sp. nov. on the basis of specimens collected on Macclesfield Bank in the South China Sea, on the Chesterfield and Island of Pines plateau of New Caledonia, and off the New Ireland Province of Papua New Guinea, respectively. These new species are morphologically distinct from all other known species of Chelidoperca by body color pattern and combinations of a few identified characters. We also redescribe one of the lesser known species, C. lecromi, from fresh specimens collected close to its type locality Lee et al. Phylogeny and Diversity of Perchlets and a new site in the Coral Sea. The distributional records for this and other known species are updated accordingly. Genetic references of the species as well as an updated identification key to western Pacific species are also provided.
