The enchytraeid fauna of Mt. Hallasan (Jeju Island, Korea) was studied in 2016, and 21 enchytraeid species were recorded and identified in total. A combination of morphological and molecular analyses (based on CO1, ITS and H3 sequences) was applied. Here we give descriptions of eight new species of Enchytraeidae (Clitellata): Achaeta koreana sp. n., Achaeta macroampullacea sp. n., Bryodrilus hallasanensis sp. n., Chamaedrilus baekrokdamensis sp. n., Enchytronia seongpanakiensis sp. n… 

A history of study and new records of terrestrial enchytraeids (Annelida, Clitellata, Enchytraeidae) from the Russian Far East

The Russian Far East, especially its southeastern part, is of great interest as a possible location for new species of enchytraeids as well as the literature and extensive field data collected by the authors in 2019.

Extending the geographic distribution of Bryodrilus ehlersi (Annelida, Enchytraeidae): morphological and molecular comparison of Korean and European specimens

Cryptic species are such evolutionary lineages that differ genetically but cannot or can only be hardly differentiated with traditional morphological methods, so they are classified as the same

This Special Volume of Zootaxa unites forty papers written in honor of András Zicsi with 71 new species-group taxa, 60 species and subspecies of earthworms and 11 species of enchytraeids.

Cryptic Clitellata: Molecular Species Delimitation of Clitellate Worms (Annelida): An Overview

A historical overview of the data and methods used to delimit clitellates from the mid-1970s to today is given and the taxonomical treatment of the cryptic species is discussed, including the recommendation that cryptic species should be described and named.

A morphology-based identification key to the Cognettia species of the world (Clitellata: Enchytraeidae)

Morphological characters for identification of Cognettia species are presented both as a dichotomous key and in table form. Focus is on non-sexual characters, as many species reproduce mainly

Two new enchytraeid species from Jeju Island, Korea (Annelida, Clitellata)

Molecular phylogenetic analyses supported the morphological results and confirmed the status of the two new species, A.multisacculatasp.



New enchytraeid species (Enchytraeidae, Oligochaeta) from Korea.

Molecular taxonomical analyses show that the Korean species resembling H. ventriculosa is not identical with the European species, furthermore sequence analysis of individuals morphologically identified as F. seoraksani indicate the possibility of species-complexity and the presence of cryptic species.

Mata Atlântica enchytraeids (Paraná, Brazil): A new genus, Xetadrilus gen. nov., with three new species, and four new species of Guaranidrilus Černosvitov (Enchytraeidae, Oligochaeta)

Seven new species of terrestrial Enchytraeidae (Oligochaeta) are described from soils of the southern Brazilian Atlantic rain forest. They were found in the framework of the German-Brazilian project

Enchytraeidae (Oligochaeta) from taiga and tundra habitats of northeastern U.S.S.R.

Mesenchytraeus diverticulatus has an esophageal expansion and intestinal diverticula that are unique within this genus, and another new species with complex nephridia in segment II is described, but left in uncertain generic position.

Five new species of Enchytraeidae (Annelida: Clitellata) from Mediterranean woodlands of Italy and reaffirmed validity of Achaeta etrusca, Fridericia bulbosa and F. miraflores

Five new enchytraeid species are described from Mediterranean woodland habitats of Italy and the name Fridericia bulbosa is retained for animals fitting the original description of Neoenchytraeus bulbosus Rosa, 1887, challenging the view that later confusion makes it a nomen dubium.

Four new terrestrial species of Marionina (Clitellata, Enchytraeidae) from China and re-examination of M. hoVbaueri Möller

Four terrestrial species of Marionina are new to science and well illustrate the taxonomic complexity of the genus as currently defined, and the assignment of these species to this large assemblage should be regarded as tentative.


Nineteen known species are new records for Italy, while 30 previous Italian records are confirmed, and two old taxa are revalidated and their descriptions augmented, and another two are redescribed from new material.

Descriptions of two new and one newly recorded enchytraeid species (Clitellata, Enchytraeidae) from the Ozegahara Mire, a heavy snowfall highmoor in Central Japan.

Three species of semi-aquatic freshwater Enchytraeidae of the genera Mesenchytraeus Eisen, 1878, Chamaedrilus Friend, 1913 and Globulidrilus Christensen & Dózsa-Farkas, 2012 are described from

Comparative morphological and molecular taxonomic study of six Achaeta species (Clitellata: Enchytraeidae) with the description of a new Achaeta species from Kőszeg Mountains, Hungary.

Comparative morphological and molecular taxonomic investigations were performed with several individuals representing these six Achaeta species and a new species is found, described here as A. tothi sp.

A new genus Globulidrilus and three new enchytraeid species (Oligochaeta: Enchytraeidae) from Seoraksan National Park (Korea)

From the Seoraksan National Park, Korea, a new enchytraeid genus, Globulidrilus gen. nov., is defined and three new species are described and the species name riparia is retained for a variant of common occurrence in Europe.
