Morphological analysis of Rhynchospio aff. asiatica (Annelida: Spionidae) and comments on the phylogeny and reproduction of the family Spionidae [PDF]

open access: yesJournal of Oceanology and Limnology, 2022
The genus Rhynchospio has fronto-lateral horns on prostomium, paired branchiae from chaetiger 2 to near the posterior end, capillary notochaetae only, and more than two pairs of pygidial cirri. Rhynchospio species are common in coastal soft bottom communities; nevertheless, many recorded Rhynchospio specimens around the world are currently undescribed.

Complete mitochondrial genome of the abalone shell-boring Polydora hoplura (Polychaeta, Spionidae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2022
Polydora hoplura Claparede 1868 (Polychaeta, Spionidae) is a mollusk shell-boring species which has been reported as a harmful species. In the present study, we sequenced and reported the mitochondrial genome (mitogenome) of P. hoplura from Korea.

Rhynchospio aciliata sp. nov., a new spionid species (Annelida, Spionidae) from the Korea Strait [PDF]

open access: yesZooKeys, 2022
A new spionid polychaete, Rhynchospio aciliata sp. nov., was discovered in the fine sandy sediments of an intertidal habitat from Korean waters. The new species is considered a simultaneous hermaphrodite, but no brooding embryos were found in any of the ...

Abundance, biomass and species richness of macrozoobenthos along an intertidal elevation gradient [PDF]

open access: yesEcology and Evolution, Volume 13, Issue 12, December 2023., 2023
This study investigates the spatio‐temporal dynamics of macrozoobenthos communities on back‐barrier tidal flats in the East Frisian Wadden Sea. They found significant changes in species composition and a decrease in abundance and species richness from west to east on the East Frisian Islands, while extremely high total organic carbon content was ...

New species of the genus Spio (Annelida, Spionidae) from the southern and western coasts of Korea [PDF]

open access: yesZooKeys, 2021
A new spionid polychaete, Spio pigmentata sp. nov., is described from the southern and western coasts of Korea. This new species differs from its congeners by the combination of the following morphological characteristics: the presence of orange-brown ...

Palps across the tree – the neuronal innervation and development of sensory head appendages in Annelida [PDF]

open access: yesFrontiers in Neuroscience, 2023
Polychaetes inhabit a wide variety of habitats and show a great morphological diversity. In this context, a key morphological structure for adapting to their individual lifestyles and ecological niches are the prominent head appendages. In the last years

Mitochondrial genomes of two Polydora (Spionidae) species provide further evidence that mitochondrial architecture in the Sedentaria (Annelida) is not conserved [PDF]

open access: yesScientific Reports, 2021
Contrary to the early evidence, which indicated that the mitochondrial architecture in one of the two major annelida clades, Sedentaria, is relatively conserved, a handful of relatively recent studies found evidence that some species exhibit elevated ...

Species delimitation and phylogenetic relationships of the Prionospio complex (Annelida, Spionidae) in the Northeast Atlantic [PDF]

open access: yesZoologica Scripta, Volume 53, Issue 3, Page 358-375, May 2024.
The Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. In this study, we assessed the
