“…The estimated global biodiversity of coral reefs is approximately 950,000 (±40%) species, of which 90% are not yet described (Fisher et al 2015). One reason marine biodiversity is globally underestimated is that there are many small and cryptic species that are usually overlooked in diversity assessments (Wolf et al 1983; Hoeksema 2017; Lau et al 2018, 2019; Sabroux et al 2019). An estimate from 2002 indicated that 25% of the world’s coral reefs have already been severely damaged due to global warming (Goreau et al 2000; Roberts et al 2002), pollution, and destructive fisheries methods (dynamite and poison) (Polunin and Roberts 1996; Roberts et al 2002; Hughes et al 2017; Heery et al 2018).…”

Sabah, Malaysia, is well known for its extensive and diverse coral reefs. It is located on the northwestern edge of the Coral Triangle, the region with the highest marine biodiversity. Much of the marine fauna here is still unknown, especially inconspicuous animals, such as small stoloniferous octocorals, which are common on coral reefs. Here, we describe two new monospecific genera of the family Arulidae found off the coast of Kota Kinabalu, Sabah, East Malaysia; Bunga payunggen. nov. et sp. nov. and Laeta waheedaegen. nov. et sp. nov. As well, the stoloniferan genus Phenganax Alderslade & McFadden, 2011 belonging to the family Clavulariidae is expanded with three new species, P. marumisp. nov., P. subtilissp. nov., and P. stokvisisp. nov., which are all sclerite-free. Additionally, we report a possibly undescribed species, closely related to the clavulariid genera Azoriella Lopez-Gonzalez & Gili, 2001 and Cervera Lopez-Gonzalez et al., 1995. As this and other recent studies have shown, discoveries of small stoloniferous octocorals are helping to fill gaps in our knowledge of the overall systematics of Octocorallia.

“…The 5ʹ region of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene was previously sequenced in Sabroux et al (2019b) for most specimens examined herein in order to resolve taxonomic issues. The material was recounted after this study, and identifications were checked and updated.…”

“…Types and examined material are deposited in the Muséum national d'Histoire naturelle, Paris (collection numbers MNHN-IU-xxx-xxx). MK numbers correspond to GenBank accession numbers published in Sabroux et al (2019b). Measurements of described holotypes were taken on drawings which were produced using a camera lucida; the trunk was measured from the chelifore insertion to the base of the abdomen, chelifores were measured as the cumulative size of the different articles and other measurements were performed measuring the distance from the proximal insertion to the tip.…”

“…Sea spiders (Arthropoda: Pycnogonida) of the Tropical Northwestern Atlantic (TNWA; Spalding et al 2007) have been the focus of about 45 publications (listed in Sabroux et al 2019b), with 132 species known from the region. Despite that this diversity already represents about 9% of the total of known species of Pycnogonida, we demonstrated in a previous account of Martinique fauna based on the European Journal of Taxonomy 851: 1-141 (2022) 2 Madibenthos Expedition samples (Sabroux et al 2019b) how lacunar our knowledge of TNWA sea spiders is regarding all together a high rate of undescribed species and the poor knowledge of species repartition. Species delimitation analyses performed with DNA barcoding data also give a hint on how abyssal the unexplored pit of cryptic species is.…”

This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.
