“…Deeper reefs (>30 m) are thought to provide areas where coral reef taxa can survive during periods of adverse conditions elsewhere (Bongaerts et al, 2015;Smith et al, 2014), and may assist recovery of shallow-water reefs by restocking them with larvae (Bongaerts et al, 2015;Costantini et al, 2011;Vaz et al, 2016). However, mesophotic reefs are not immune to disturbance, and if they are to act as depth refuges, they need to be resilient and sustain populations that connect with those in other reef habitats (Abesamis et al, 2018;Bongaerts & Smith, 2019;Pinheiro et al, 2019). Understanding variability across reef habitats in protected isolated reefs subject to low levels of environmental disturbance may provide further insights into the overall capacity of reefs to survive rapid ongoing change under ecologically optimal conditions (Knowlton & Jackson, 2008;Skinner et al, 2020).…”

“…In this study, the combination of different observational and fishing (Baldwin et al, 2018;Kane et al, 2014;Pinheiro et al, 2019;Rocha et al, 2018;Wagner et al, 2014), including in the SA (Feitoza et al, 2005;Francini-Filho et al, 2019;Pinheiro et al, 2015;Rosa et al, 2016;Simon et al, 2016). The increase in the depth range of scientific exploration is contributing to a better understanding of the distribution of the world's marine biodiversity and accelerating the rate of knowledge acquisition about the distributions and biogeographical patterns of marine organisms.…”

“…In this study, the combination of different observational and fishing techniques allowed the scientific exploration of shallow and deep reefs of SPSPA, as well as its surrounding pelagic environment, revealing new fish records and new species. Mesophotic and rariphotic exploration around the world have resulted in new records and discoveries (Baldwin et al ., 2018; Kane et al ., 2014; Pinheiro et al ., 2019; Rocha et al ., 2018; Wagner et al ., 2014), including in the SA (Feitoza et al ., 2005; Francini‐Filho et al ., 2019; Pinheiro et al ., 2015; Rosa et al ., 2016; Simon et al ., 2016).

Saint Peter and Saint Paul's Archipelago (SPSPA), one of the smallest and most isolated island groups in the world, is situated on the Mid-Atlantic Ridge, between Brazil and the African continent. SPSPA has low species richness and high endemism; nonetheless, the diversity of fishes from deep habitats (>30 m depth) had not been previously studied in detail. Several expeditions conducted between 2009 and 2018 explored the shallow and deep reefs of SPSPA using scuba, closed-circuit rebreathers, manned submersibles, baited remote underwater stereo-videos (stereo-BRUV) and fishing between 0 and 1050 m depth. These expeditions yielded 41 new records of fishes for SPSPA: 9 in open waters, 9 in shallow waters (0-30 m), 8 in mesophotic ecosystems (30-150 m) and 15 in deeper reefs (>150 m). Combined with literature records of adult pelagic, shallow and deep-reef species, as well as larvae, the database of the fish biodiversity for SPSPA currently comprises 225 species (169 recorded as adult fishes and 79 as larvae, with 23 species found in both stages). Most of them (112) are pelagic, 86 are reef-associated species and 27 are deep-water specialists. Species accumulation curves show that the number of fish species has not yet * These authors contributed equally to this study.

“…More than 70% of all research on MCEs has been published in the past seven years (Pyle and Copus 2019), and undoubtedly these discoveries will continue as several teams lead expeditions to global biodiversity hotspots and regions where MCEs have not been previously surveyed. Continued research on mesophotic coral ecosystems (MCEs), whether using submarines, closed-circuit rebreathers or ROVs, is documenting many new species and range extensions for fishes found at depths between 60-150 m (Pyle 2000;Baldwin et al 2016;Pinheiro et al 2016Pinheiro et al , 2019Pyle et al 2016;Rocha et al 2017;Shepherd et al 2018;Arango et al 2019;Shepherd et al 2019). Discovery rates of new species are as high as two new species per hour of exploration (Pinheiro et al 2019).…”

Discovery rates of new species are as high as two new species per hour of exploration (Pinheiro et al 2019). This, coupled with ecological observations, has led to the conclusion that mesophotic coral reefs are unique and threatened (Baldwin et al 2018;Rocha et al 2018).…”

Two new species of Plectranthias perchlets are described, collected from mesophotic coral ecosystems in French Polynesia and the Republic of the Marshall Islands, in the tropical Central Pacific. Plectranthias polygoniussp. nov. was collected at a depth of 105 m in Tahiti, French Polynesia, and 120 m in Maloelap Atoll, Republic of the Marshall Islands. It was also observed in Moorea and Rangiroa (French Polynesia), and at Majuro and Erikub Atolls, Republic of the Marshall Islands. Plectranthias hinanosp. nov. was collected at a depth of 90–98 m in Tahiti, French Polynesia, and observed in Moorea. The barcode fragment of the cytochrome oxidase I gene of Plectranthias polygoniussp. nov. does not closely match any published sequence of Plectranthias, with approximately 15% uncorrected divergence from several species. Plectranthias polygoniussp. nov. can be distinguished from all of its congeners by coloration and morphology. The barcode fragment of the COI gene of Plectranthias hinanosp. nov. is closest to Plectranthias bennetti, with 5.4% uncorrected divergence. Plectranthias hinanosp. nov. is also distinguished from all of its congeners by morphology, and a coloration that includes two indistinct black spots along the base of the dorsal-fin, and transparent yellow dorsal and anal fin membranes. With this publication, the genus Plectranthias now comprises 58 valid species, with representatives from tropical to temperate waters of the Atlantic, Pacific, and Indian oceans. These two new discoveries add to the growing body of research highlighting the rich biodiversity of mesophotic ecosystems.
