“…Alderslade (2001) established the genus Ovabunda Alderslade, 2001 for previously described species of Xenia Lamarck, 1816 with the corpuscular sclerite-type, while retaining those with a dendritic surface in the original genus. To date, the phylogenetic studies on Xeniidae support the hypothesis that their distinct sclerite microstructure justifies establishing generic boundaries within this family (Haverkort-Yeh et al 2013, McFadden et al 2014). …”

“…Members of the octocoral family Xeniidae form a major faunistic component on shallow Indo-Pacific coral reefs (e.g., Alderslade 2001, Janes 2013, McFadden et al 2014, Halàsz et al 2014, 2015). They play a significant ecological role in coral reef ecosystems, exhibiting a rapid colonization rate (e.g., Tilot et al 2008, Wild and Naumann 2013) as well as invasive capabilities (Ruiz-Allais et al 2014).…”

Several species of the family Xeniidae, previously assigned to the genus Cespitularia Milne Edwards & Haime, 1850 are revised. Based on the problematical identity and status of the type of this genus, it became apparent that the literature has introduced misperceptions concerning its diagnosis. A consequent examination of the type colonies of Cespitularia coerulea May, 1898 has led to the establishment of the new genus Conglomeratusclera gen. n. and similarly to the assignment of Cespitularia simplex Thomson & Dean, 1931 to the new genus, Caementabunda gen. n. Both new genera are described and depicted and both feature unique sclerite morphology, further highlighting the importance of sclerite microstructure for generic position among Xeniidae. Freshly collected material was subjected to molecular phylogenetic analysis, whose results substantiated the taxonomic assignment of the new genera, as well as the synonymies of several others.

“…Sequences were aligned to a reference set of published sequences for other xeniid taxa (Haverkort-Yeh et al 2013; McFadden et al 2014b) using the L-INS-i method in MAFFT (Katoh et al 2005). Pairwise genetic distances (Kimura 2-parameter) among specimens were calculated using the DNADist program in PHYLIP v. 3.69 (Felsenstein 2005).…”

A new species of Ovabunda (Octocorallia, Xeniidae) from the Andaman Sea, Thailand with notes on the biogeography of this genus

A survey of xeniid octocorals was carried out in the waters off Southwestern Thailand in September, 2007. Microscopic investigation of the colonies revealed that three specimens belonged to the genus Ovabunda. Gross morphological examination is presented here accompanied by scanning electron micrographs of the sclerites. Molecular phylogenetic analysis showed identical genotypes at mtMutS, COI, and 28S rDNA for all three specimens and supports their generic assignment. Colony size and shape, sclerite size, and pinnule arrangement differ from nominal species of Ovabunda and thus a new species, O. andamanensis is introduced here. This work also presents a new eastern geographical record for the genus Ovabunda.

“…mtMutS (699 bp) and COI (coding region only, 560 bp) were aligned with the comprehensive, 130-taxon dataset of McFadden and Ofwegen (2012), which includes representatives of all other sclerite-free octocoral taxa for which molecular data are available: Acanthoaxis wirtzi , Acrossota amboinensis , Cervera atlantica (Johnson, 1861), Cornularia cornucopiae and C. pabloi , Malacacanthus capensis , Phenganax parrini , Xenia hicksoni , and an undescribed species of Xenia from Indonesia ( Xenia sp. 3, see: McFadden et al 2014). Phylogenetic analyses followed the procedure of McFadden and Ofwegen (2012) using a combined dataset with different models of evolution applied to two separate data partitions, mitochondrial genes ( mtMutS + COI ; TVM+I+G) and 28S rDNA (GTR+I+G).…”

This communication describes a new octocoral, Altumia delicata gen. n. & sp. n. (Octocorallia: Clavulariidae), from mesophotic reefs of Eilat (northern Gulf of Aqaba, Red Sea). This species lives on dead antipatharian colonies and on artificial substrates. It has been recorded from deeper than 60 m down to 140 m and is thus considered to be a lower mesophotic octocoral. It has no sclerites and features no symbiotic zooxanthellae. The new genus is compared to other known sclerite-free octocorals. Molecular phylogenetic analyses place it in a clade with members of families Clavulariidae and Acanthoaxiidae, and for now we assign it to the former, based on colony morphology. The polyphyletic family Clavulariidae is, however, in need of a thorough revision once the morphological distinctions among its phylogenetically distinct clades are better understood.
