“…While it seems clear that Hermundura is not a pilargid, it is also not necessarily part of Microphthalmidae. Hermundura features, such as a relatively long body length (most species of Hermundura are longer than 5 mm) [12,64,65,74,78,[91][92][93][94][95][96][97][98][99][100], usual absence of antennae and enlarged anterior cirri on achaetous anterior segments, small biarticulated palps, terminal pharyngeal papillae, and the absence of dorsal cirri (a feature of all Hermundura species besides H. aberrans (Monro, 1936) [65]), are not seen not in microphthalmids [89]. Further anatomical and molecular studies are needed before Hermundura can with certainty be considered within Microphthalmidae or as a sister taxon to it.…”

Pilargidae is a family of free-living and burrowing marine annelids. A lack of available molecular data for most of these species has precluded a molecular assessment of their phylogenetic relationships and has left uncertain the placement of Antonbruunia, which is hypothesized to be either a member of Pilargidae or its sister clade, the monotypic family Antonbruunidae. In this study, we describe the new species Antonbruunia milenae sp. nov., found at 845 m of depth off the coast of San Diego, California, USA, and we address the phylogeny of these organisms using 15 novel mitogenomes and multiple Sanger-sequenced loci. Our results show that Antonbruunia falls within Pilargidae, making Antonbruunidae a junior synonym of Pilargidae. Glyphohesione was transferred from Pilarginae to Synelminae, the previously unassigned genera Otopsis and Antonbruunia were shown to belong within Synelminae, and Hermundura was assigned to Phyllodocida incertae sedis. Sigambra was found to be non-monophyletic. Four different mitogenome gene orders were found among Pilargidae. Changes between the gene orders and the ancestral state gene order of the family were inferred. Two species have introns within the COI gene. These efforts represent a significant expansion of the available molecular resources for pilargids, as well as the basis for a more stable taxonomy.

“…However, its diversity is still underestimated in numerous seas, despite the availability of several smallscale regional taxonomic reviews [9][10][11]. The prostomium, thorax, and abdominal lateral pouches, pivotal defining morphological characteristics of the Magelona F. Müller, 1858 [12], species, are sometimes susceptible to damage during the collection process, posing challenges regarding morphological identification to the species level [13,14]. Particularly, the parapodia consist of delicate lamellae that may partially break or fold during the initial sample processing and sieving.…”

This study assessed the taxonomic statuses of three lesser-known Magelona F. Müller, 1858 species collected from intertidal to sublittoral habitats in Korean coastal waters, basing identification on morphological features and comparing them with their closest congeners. We present a comprehensive description and illustration of taxonomically significant and standardized characters, covering all thoracic chaetigers of three newly discovered Magelona species from Korea. Within the documented Korean Magelona species, these three species exhibit the following distinctive characteristics. Magelona sachalinensis Buzhinskaja, 1985, possess diminutive superior dorsal lobes in the initial four chaetigers and specialized chaetae on chaetiger 9; Magelona lenticulata Gallardo, 1968, is characterized by foliaceous postchaetal superior dorsal lobes in chaetigers 1–8; and Magelona cf. longicornis Johnson, 1901, is distinguished by notably elongated noto- and neuropodial postchaetal lamellae on chaetiger 9. Methyl green staining patterns showed species-specific characteristics and were confirmed to be effective in distinguishing the examined Korean species from each other and useful for making comparisons with previously reported Magelona species. Our study suggests that further comprehensive research on the morphological and genetic characteristics of Magelona species will enhance our understanding of their diversity.
