Three new enchytraeid species (Enchytraeidae, Annelida) from mountain soils of Korea and ten species new for the country.

In this paper, three new enchytraeid species (Enchytraeidae, Clitellata) are described from different mountains of Korea: Cognettia koreana sp. n., Henlea bidiverticulata sp.

Decimodrilus, a new enchytraeid genus from Korea (Annelida, Clitellata, Enchytraeidae).

Two new species of the new genus Decimodrilus gen. n. are described in this paper from oak forests of South Korea using a combination of classical morphology and DNA-based molecular taxonomy.

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

The enchytraeid fauna of three areas in Jeju Island (Korea) was studied, and comparative morphological and molecular taxonomic examinations (based on CO1, ITS and H3 sequences) were performed on nine samples collected in 2016. Twenty-two enchytraeid species were recorded and identified. The descriptions of two new species ( and ) are presented in this paper.

New enchytraeid species from Mount Hallasan (Jeju Island, Korea) (Enchytraeidae, Oligochaeta).

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.

Morphological and molecular distinction of two Fridericia species (Clitellata, Enchytraeidae) having same spermatheca type.

One enchytraeid species, proved to be new to science, is described in this paper as Fridericia ventrochaetosa sp. nov. The new species is distinguished from similar species, especially from F.

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

Five Achaeta species (A. affinis, A. bohemica sensu stricto, A.

A new species (Clitellata: Enchytraeidae) and its comparison with other species from mires in Hungary.

Results of a comparative investigation on five Cernosvitoviella species from Hungarian Sphagnum mires including their distribution and the description of a new species, Cernosvitoviella farkasi sp. n., are presented in this paper.

New enchytraeid species (Enchytraeidae, Oligochaeta) from Korea.

We give descriptions of five new enchytraeid species (Enchytraeidae, Oligochaeta) from Korea: Henlea magnaampullacea sp. n., Fridericia sphaerica sp.

Unexpected occurrence of Hemifridericia bivesiculata Christensen & Dózsa-Farkas, 2006 in Hungary, a species presumed to be endemic to Devon Island, Canada, and its comparative analysis with H. parva Nielsen & Christensen, 1959 (Enchytraeidae, Oligochaeta).

During the exploration of the enchytraeid fauna in forests and grasslands of Hungarian flat areas, a small enchytraeid species, Hemifridericia bivesiculata Christensen & Dózsa-Farkas, 2006, was found unexpectedly. This species was known previously only from one single location, Bank Island in the Canadian archipelago, and was presumed to be endemic. Here, the distinctive features of the two Hemifridericia species are described based on detailed morphological analyses, which were supported with molecular methods.

Three new Fridericia species (Oligochaeta, Enchytraeidae) from Transylvania, Romania.

We give descriptions of three new Fridericia species (Enchytraeidae, Oligochaeta) from Transylvania, Romania. Fridericia transylvanica sp. n.
