“…These O. brunnea were collected in Phuket, Thailand. In the phylogenetic analysis in the present study, the sequences of O. brunnea of Fisher et al (2004) and Pérez-Losada et al (2012) were clustered in the same clade as the O. intermedia collected from Phuket and Krabi in the present study, suggesting that these specimens of O. brunnea in Fisher et al (2004) and Pérez-Losada et al (2012) are O. intermedia. Octomeris angulosa is recorded from South African waters, and there are no other records outside this region.…”

“…Many sister taxa or distinct population genetic divergences in other marine species, including Tetraclita and Chthamalus barnacles and coral reef fishes, also formed when the Indian and Pacific Oceans separated during the last glacial maxima (Bowen et al 2001;Tsang et al 2011Tsang et al , 2012. Fisher et al (2004) and Pérez-Losada et al (2012) included Octomeris brunnea in their phylogenetic studies. These O. brunnea were collected in Phuket, Thailand.…”

“…The phylogenetic trees were reconstructed from COI and 12S rRNA sequences using neighbor-joining (NJ), Bayesian inferences (BI), and maximum likelihood (ML) conducted in MEGA X 10.0.5, MrBayes 3.2.6, and W-IQ-TREE, respectively (Kumar et al 2018;Nguyen et al 2015;Ronquist and Huelsenbeck 2003;Trifinopoulos et al 2016). Selected sequences of Chthamalidae downloaded from GenBank were included in the analysis, and the Catomerus polymerus sequence was used as the outgroup (Chan et al 2018;Chen et al 2019;Fisher et al 2004;Pérez-Losada et al 2004;Pérez-Losada et al 2012;Wares 2013;Wares et al 2009) (Table 1).…”

“…All the phylogenetic results suggested that both Octomeris brunnea and O. intermedia were clustered their own clades with high bootstrap values and posterior probabilities. The sequences from Fisher et al (2004) and Pérez-Losada et al (2012), which were designated as O. brunnea, were clustered with O. intermedia collected from Malaysia and Thailand by the NJ method (Fig. 17A, B).…”

“…In the early 19 th century, studies on the biology and ecology of Octomeris were very rare because this species inhabits shaded habitats and its presence was often overlooked (Nilsson-Cantell 1938). A recent molecular phylogenetic analysis of the family Chthamalidae included two species of Octomeris (Pérez-Losada et al 2012) and considered Octomeris as paraphyletic; molecular evidence does not support the hypothesis that plate number decreased from eight plates to six, then four in the chthamalid evolution (Pérez -Losada et al 2012).…”

Octomeris is a chthamalid intertidal barnacle with eight shell plates. There are currently two species of such barnacles: O. brunnea Darwin, 1854 (type locality in the Philippines), common in the Indo-Pacific region, and O. angulosa Sowerby, 1825, only recorded in South Africa. Octomeris intermedia Nilsson-Cantell, 1921, identified from the Mergui Archipelago in Myanmar, was considered to be conspecific with O. brunnea by Hiro (1939) based on samples collected in Taiwan. The morphological differences in shell and opercular plates between O. brunnea and O. intermedia are believed to be intra-specific variations due to different degrees of shell erosion. In the present study, the genetic and morphological differentiations of Octomeris in the Indo-Pacific region were examined. This study found two molecular clades (with inter-specific differences) based on the divergence in the COI genes, and the species also have distinct geographical distributions. The Octomeris brunnea clade covers samples collected from the Philippines and Taiwan waters and the other clade, which we argue is O. intermedia, is distributed in Phuket and Krabi, Thailand and Langkawi, Malaysia. Phuket and Krabi are located approximately 300 km south of the Mergui Archipelago, the type locality of O. intermedia. The morphology of samples collected from Thailand fits the type description of O. intermedia in Nilsson-Cantell (1921). Our study concludes that O. intermedia is a valid species based on morphological and molecular evidence.

Coral-inhabiting barnacles (Thoracica: Pyrgomatidae) are obligatory symbionts of scleractinian and fire corals. We attempted to reconstruct the phylogeny of coral-inhabiting barnacles using a multi-locus approach (mitochondrial 12S and 16S rRNA, and nuclear EF1, H3 and RP gene sequences, total 3532bp), which recovered a paraphyletic pattern. The fire-coral inhabiting barnacle Wanella milleporae occupied a basal position with respect to the other coral inhabiting barnacles. Pyrgomatids along with the coral-inhabiting archaeobalanid Armatobalanus nested within the same clade and this clade was subdivided into two major lineages: Armatobalanus+Cantellius with species proposed to be the ancestral stock of extant coral barnacles, and the other comprising the remaining genera studied. Ancestral state reconstruction (ASR) suggested multiple independent fusions and separations of shell plates and opercular valves in coral barnacle evolution, which counters the traditional hypothesis founded on a scheme of morphological similarities. Most of the coral barnacles are restricted to one or two coral host families only, suggesting a trend toward narrow host range and more specific adaptation. Furthermore, there is a close linkage between coral host usage and phylogenetic relationships with sister taxa usually being found on the same coral host family. This suggests that symbiotic relationships in coral-inhabiting barnacles are phylogenetically conserved and that host associated specialization plays an important role in their diversification.
