“…Our main objective has been to provide taxonomic hypotheses on macrofaunal annelids collected from the targeted areas within the CCZ based on morphology and molecular data. These data build up on previous taxonomic work on annelids from the target areas ( Wiklund et al 2019 ; Drennan et al 2021 ; Neal et al 2022 ) as well as wider CCZ area ( Janssen et al 2015 ; Blake 2019 ; Bonifácio and Menot 2019 ) and ultimately provide further insights into annelid species distribution in the deep-sea realm. Up to this date, 52 annelid species have been formally described from CCZ , with the focus on families Spionidae ( Paterson et al 2016 ; Neal et al 2022 ), Orbiniidae ( Blake 2017 , 2020 ), Polynoidae ( Bonifácio and Menot 2019 ), Cirratulidae ( Blake 2016 , 2019 ), Opheliidae , Scalibregmatidae , and Travisiidae ( Wiklund et al 2019 ), Syllidae ( Maciolek 2020 ) and Nereididae ( Drennan et al 2021 ).…”

“…This study has added six annelid species, three of those formally described and one likely new, and 41 records to the knowledge of the benthic annelid macrofauna of the CCZ, bringing a published record from the targeted areas (Fig. 1) to 54 annelid species, with 19 of them formalised (see also Wiklund et al 2019;Drennan et al 2021).…”

“…To summarise, the number of DNA sequences for benthic faunal groups from the CCZ available on GenBank are growing, representing echinoderms (e.g. Glover et al 2016a ; Christodoulou et al 2020 ), cnidarians ( Dahlgren et al 2016 ), molluscs ( Wiklund et al 2017 ), annelids ( Janssen et al 2015 ; Bonifácio and Menot 2019 ; Wiklund et al 2019 ; Guggolz et al 2020 ; Drennan et al 2021 ; Neal et al 2022 ), poriferans ( Lim et al 2017 ) and crustaceans (e.g. Janssen et al 2015 ; Kaiser et al 2018 ; Bribiesca-Contreras et al 2021 ; Mohrbeck et al 2021 ).…”

This is a contribution in a series of taxonomic publications on benthic fauna of polymetallic nodule fields in the eastern abyssal Clarion-Clipperton Zone (CCZ). The material was collected during environmental surveys targeting exploration contract areas ‘UK-1’, ‘OMS’ and ‘NORI-D’, as well as an Area of Particular Environmental Interest, ‘APEI-6’. The annelid families Amphinomidae and Euphrosinidae are investigated here. Taxonomic data are presented for six species from 41 CCZ-collected specimens as identified by a combination of morphological and genetic approaches; of the six species, three are here described as new, one species is likely to be new but in too poor condition to be formalised and the two others likely belong to known species. Description of three new species Euphrosinella georgievaesp. nov., Euphrosinopsis ahearnisp. nov., and Euphrosinopsis hallisp. nov. increases the number of formally described new annelid species from the targeted areas to 21 and CCZ-wide to 52. Molecular data suggest that four of the species reported here are known from CCZ only, but within CCZ they have a wide distribution. In contrast, the species identified as Bathychloeia cf. sibogae Horst, 1910 was found to have a wide distribution within the Pacific based on both morphological and molecular data, using comparative material from the abyssal South Pacific. Bathychloeia cf. balloniformis Böggemann, 2009 was found to be restricted to APEI-6 based on DNA data available from CCZ specimens only, but morphological data from other locations suggest potentially a wide abyssal distribution. The genus Euphrosinopsis was previously known only from Antarctic waters, and Euphrosinella georgievaesp. nov. was recovered as a sister taxon to the Antarctic specimens of Euphrosinella cf. cirratoformis in our molecular phylogenetic analysis, strengthening the hypothesised link between the deep-sea and Antarctic benthic fauna.

“…This study has added 25 annelid species, two of those formalized, and 98 records to the knowledge of the benthic annelid macrofauna of the CCZ, bringing a published record from the ABYSSLINE (UK-1 and OMS) investigated areas to 48 polychaete species, with 15 formalized (see also Wiklund et al 2019;Drennan et al 2021). Additional studies to either provide taxonomic data for or to formalize remaining ABYSSLINE polychaetes are currently underway by the authors.…”

This paper represents a continuation of taxonomic publications on the benthic fauna of polymetallic nodule fields in the eastern Clarion-Clipperton Zone (CCZ) using material collected during baseline environmental survey work targeting two exploration contract areas (“UK-1” and “OMS”) and one Area of Particular Environmental Interest, “APEI-6.” Families Poecilochaetidae Hannerz, 1956 and Spionidae Grube, 1850 of the annelid suborder Spioniformia were studied here. Taxonomic data are presented for 25 species from 98 records as identified by a combination of morphological and genetic approaches. Although sub-optimal morphological condition can prevent new species being formally described, it is essential that morphological, molecular, and voucher data are made available for future surveys. Descriptions of two new species—Poecilochaetus brenkei sp. nov. and Laonice shulseae sp. nov.—increase the number of formally described new annelid species from the areas targeted in this study to 15 and CCZ-wide to 46. We also discuss the commonly reported “cosmopolitan” deep-sea spionid Aurospio dibranchiata Maciolek, 1981, which we show represents several genetically distinct species (three of these from CCZ area alone) but without reliable morphological characters to separate them. Molecular data provide evidence that 15 out of 25 species reported here have a wide distribution within the eastern CCZ and that Aurospio sp. “NHM_2186” and the known species Prionospio amarsupiata Neal & Altamira in Paterson et al. 2016 may be cosmopolitan. Lastly, the molecular data provide insights into relationships within Spioniformia, suggesting that both Poecilochaetidae and Trochochaetidae belong within Spionidae.

“…Indeed, two recent molecular analyses of Neanthes (Drennan et al, 2021;Villalobos-Guerrero et al, 2022) has further reinforced the idea of Neanthes as a convoluted genus, when members of this group were recovered as sister taxa or taxon to other genera such as Alitta, Cheilonereis, Dendronereis and Nectoneanthes. Within that same study, Villalobos-Guerrero et al, 2022 remarks on the issue with identification uncertainty and misidentification of many species and how only slightly above 10% of all nereidids have their COI sequence available in the Barcode of Life Database or GenBank.…”

Robust phylogenomic inference through genome skimming as demonstrated by a systematic analysis of Nereididae

The introduction of massively parallel sequencing in the mid-2000s has truly revolutionized the field of molecular phylogenetics and ultimately our understanding of the tree of life. Despite today's existence of long-read sequencing and hybrid strategies-with the ability to produce high-quality, near-chromosome-level assemblies-monetary costs, sampling restrictions, and other practical considerations still favors next-generation sequencing (NGS) in many instances. To this date, most large-scale phylogenetic or "phylogenomic" studies were conducted using a "genome reduction" strategy such as transcriptome sequencing or target enrichment. Until recently, whole-genome sequencing (WGS) was often dismissed or overlooked due higher sequencing costs and a lack of appropriate bioinformatic tools to process the data downstream. Despite this, WGS has many advantages over other techniques such as reduced laboratory workload, smaller DNA volume and quality requirements, and higher data re-usability, even outside phylogenetics. Now, advancements in short-read sequencing technology has reduced the costs of sequencing and the development of new, alignment-based bioinformatic software for working with WGS data should have phylogeneticists reconsider this sequencing approach. Still, we saw the need for a fast, scalable, and easy-to-use method for mining desired loci from raw reads or assembled contigs. Thus, we here present Patchwork, a new, alignment-based program, which mines phylogenetic markers from WGS data by "stitching" overlapping and or adjacent sequence regions. A novel sliding-window based algorithm trims non-coding regions from extracted markers. We ultimately demonstrate the utility of both Patchwork-and for using WGS in a phylogenomic context-by using this tool to reconstruct the phylogeny of the annelid family Nereididae. All previous attempts to infer the phylogeny of Nereididae have been limited to morphological data or by using one or a handful of mitochondrial genes. Most of these studies were also severely limited in taxonomic coverage. Here, we present trees inferred from a set of 777 near-universal single-copy orthologs and mitochondrial genomes, containing a total of 100 and 132 taxa respectively, to produce a well-supported and congruent phylogeny of the group.
