Spawning times and breeding trials suggest no inbreeding occurs between Porites aff. lutea and P. cf cylindrica
No full textMolecular approaches have advanced our understanding of reef coral biodiversity. However, in some taxa, they have yet to deliver a robust taxonomy that reflects differences in the ecology and biology of species. For example, Porites cf. cylindrica and P. aff. lutea, which have different morphologies and life histories, are clustered close together in a complex containing several other Porites species when analyzed using both single locus molecular markers and thousands of SNPs from ezRAD data. This suggests the possibility of recent or ongoing speciation and/or hybridization between these species. Here, we used the timing of gamete release and gamete compatibility to test reproductive boundaries between the two. At Orpheus Island (Australia), P. cf. cylindrica and P. aff. lutea spawned on the same night, while at Sesoko Island (Japan), they did not. Furthermore, when spawning occurred during in vitro breeding trials, the eggs did not cleave, suggesting that P. cf. cylindrica and P. aff. lutea are not interbreeding. Breeding trials can help resolve species identities in taxa for which molecular and morphological data provide unclear resulThis project was founded by the Higher Degree Research Enhancement (HDRES) Award 2017 to Tullia I Terraneo (ARC Centre of Excellence for Coral Reef Studies, James Cook University), the David Yellowlees Excellence in Research Award 2018 to Tullia I Terraneo (ARC Centre of Excellence for Coral Reef Studies, James Cook University), the 2018 Red Sea Research Center (RSRC) Travel Grant to Tullia I Terraneo (King Abdullah University of Science and Technology), the Australia Research Council (ARC) funds to Andrew H Baird, and King Abdullah University of Science and Technology (KAUST) baseline funds to Michael L Berumen.

Pachyseris inattesa sp. n. (Cnidaria, Anthozoa, Scleractinia): A new reef coral species from the red sea and its phylogenetic relationships
No full textA new scleractinian coral species, Pachyseris inattesa sp. n., is described from the Red Sea. Despite a superficial resemblance with some species in the agariciid genus Leptoseris with which it has been previously confused, P. inattesa sp. n. has micro-morphological characters typical of the genus Pachyseris. This genus, once part of the Agariciidae, is comprised of five extant species and is widely distributed throughout the tropical Indo-Pacific. It is currently incertae sedis as a result of recent molecular analysis and appears to be closely related to the Euphylliidae. A molecular phylogenetic reconstruction including P. inattesa sp. n., the genus type species P. rugosa, and P. speciosa, all present in the Red Sea, was performed using the mitochondrial intergenic spacer between COI and 16S-rRNA. The results confirm that P. inattesa sp. n. is a monophyletic lineage closely related to the other Pachyseris species examined. © Tullia I. Terraneo et al
