“…The present study is the third in a series of monographs that considers species traditionally placed in the suborder Faviina sensu Vaughan & Wells () and Wells (), or Faviina + Meandriina sensu Veron (). The series formally establishes a revised taxonomic classification that is based on new molecular results (Fukami et al ., ; Huang et al ., ; Arrigoni et al ., , ,c, , ), and focuses on the family and genus levels. It treats eight extant families – Meandrinidae Gray, 1847, Oculinidae Gray, 1847, Rhizangiidae d'Orbigny, 1851, Merulinidae Verrill, , Mussidae Ortmann, , Faviidae Gregory, (including Trachyphylliidae Verrill, ), Anthemiphylliidae Vaughan, , and Pectiniidae Vaughan & Wells, – mostly nested within the ‘robust’ group and shown to be nonmonophyletic (Fukami et al ., ; Kitahara et al ., ; Stolarski et al ., ; Huang, ; Huang & Roy, , ).…”

Lobophylliidae is a family-level clade of corals within the 'robust' lineage of Scleractinia. It comprises species traditionally classified as Indo-Pacific 'mussids', 'faviids', and 'pectiniids'. Following detailed revisions of the closely related families Merulinidae, Mussidae, Montastraeidae, and Diploastraeidae, this monograph focuses on the taxonomy of Lobophylliidae. Specifically, we studied 44 of a total of 54 living lobophylliid species from all 11 genera based on an integrative analysis of colony, corallite, and subcorallite morphology with molecular sequence data. By examining coral skeletal features at three distinct levelsmacromorphology, micromorphology, and microstructurewe built a morphological matrix comprising 46 characters. Data were analysed via maximum parsimony and transformed onto a robust molecular phylogeny inferred using two nuclear (histone H3 and internal transcribed spacers) and one mitochondrial (cytochrome c oxidase subunit I) DNA loci. The results suggest that micromorphological characters exhibit the lowest level of homoplasy within Lobophylliidae. Molecular and morphological trees show that Symphyllia, Parascolymia, and Australomussa should be considered junior synonyms of Lobophyllia, whereas Lobophyllia pachysepta needs to be transferred to Acanthastrea. Our analyses also lend strong support to recent revisions of Acanthastrea, which has been reorganized into five separate genera (Lobophyllia, Acanthastrea, Homophyllia, Sclerophyllia, and Micromussa), and to the establishment of Australophyllia. Cynarina and the monotypic Moseleya remain unchanged, and there are insufficient data to redefine Oxypora, Echinophyllia, and Echinomorpha. Finally, all lobophylliid genera are diagnosed under the phylogenetic classification system proposed here, which will facilitate the placement of extinct taxa on the scleractinian tree of life.

“…In each quadrat, all coral colonies were identified to the genus. Recent changes to the nomenclature of regional species (Table S1) included divisions and synonymy of a few genera (Arrigoni et al, 2016;Budd, Fukami, Smith, & Knowlton, 2012;Huang, Benzoni, Arrigoni, et al, 2014;Huang, Benzoni, Fukami, et al, 2014). Members of the synonymised genera showed minimal bleaching severity and no immediate mortality, suggesting negligible impact of taxonomic updates on bleaching patterns found among the synonymised genera (Table S2).…”

Environmental anomalies that trigger adverse physiological responses and mortality are occurring with increasing frequency due to climate change. At species' range peripheries, environmental anomalies are particularly concerning because species often exist at their environmental tolerance limits and may not be able to migrate to escape unfavourable conditions. Here, we investigated the bleaching response and mortality of 14 coral genera across high‐latitude eastern Australia during a global heat stress event in 2016. We evaluated whether the severity of assemblage‐scale and genus‐level bleaching responses was associated with cumulative heat stress and/or local environmental history, including long‐term mean temperatures during the hottest month of each year (SSTLTMAX), and annual fluctuations in water temperature (SSTVAR) and solar irradiance (PARZVAR). The most severely‐bleached genera included species that were either endemic to the region (Pocillopora aliciae) or rare in the tropics (e.g. Porites heronensis). Pocillopora spp., in particular, showed high rates of immediate mortality. Bleaching severity of Pocillopora was high where SSTLTMAX was low or PARZVAR was high, whereas bleaching severity of Porites was directly associated with cumulative heat stress. While many tropical Acropora species are extremely vulnerable to bleaching, the Acropora species common at high latitudes, such as A. glauca and A. solitaryensis, showed little incidence of bleaching and immediate mortality. Two other regionally‐abundant genera, Goniastrea and Turbinaria, were also largely unaffected by the thermal anomaly. The severity of assemblage‐scale bleaching responses was poorly explained by the environmental parameters we examined. Instead, the severity of assemblage‐scale bleaching was associated with local differences in species abundance and taxon‐specific bleaching responses. The marked taxonomic disparity in bleaching severity, coupled with high mortality of high‐latitude endemics, point to climate‐driven simplification of assemblage structures and progressive homogenisation of reef functions at these high‐latitude locations.

Lack of mitochondrial genome data of Scleractinia is hampering progress across genetic, systematic, phylogenetic, and evolutionary studies concerning this taxon. Therefore, in this study, the complete mitogenome sequence of the stony coral Echinophylliaaspera (Ellis & Solander, 1786), has been decoded for the first time by next generation sequencing and genome assembly. The assembled mitogenome is 17,697 bp in length, containing 13 protein coding genes (PCGs), two transfer RNAs and two ribosomal RNAs. It has the same gene content and gene arrangement as in other Scleractinia. All genes are encoded on the same strand. Most of the PCGs use ATG as the start codon except for ND2, which uses ATT as the start codon. The A+T content of the mitochondrial genome is 65.92% (25.35% A, 40.57% T, 20.65% G, and 13.43% for C). Bayesian and maximum likelihood phylogenetic analysis have been performed using PCGs, and the result shows that E.aspera clustered closely with Sclerophylliamaxima (Sheppard & Salm, 1988), both of which belong to Lobophylliidae, when compared with species belonging to Merulinidae and other scleractinian taxa used as outgroups. The complete mitogenome of E.aspera provides essential and important DNA molecular data for further phylogenetic and evolutionary analyses of corals.
