“…*: Specimen misidentified, see text. The lentiform glands in Achaeta etrusca Rota, 1995 may also belong here (see Rota 2015) even though a figure (Rota 2015, Fig. 4A) suggests that they are less enlarged and more similar to the ordinary lentiform gland cells such as found in A. pannonica Graefe, 1989, A. iberica Graefe, 1989, A. diddeni Graefe, 2007, and A. brevivasa Graefe, 1980 All lentiform gland cells that we consider as enlarged have two different compartments: a non-staining central region which connects with the body surface, and a strongly staining peripheral region which extends into the body cavity.…”

Achaeta (Enchytraeidae, Oligochaeta, Clitellata) is a genus of small, soil-dwelling annelids, peculiar by the absence of chaetae in all species. Here two new species of this genus are described from afforestation sites in southern Poland. Descriptions are based on the investigation of living and preserved material. The species are also characterized at the DNA level, using fragments of the COI and ITS genes, sequenced from the holotypes and paratypes. The worms are not longer than 4–6 mm, with about 30 to 35 segments, and with medium-large male and female reproductive organs. Achaeta florens sp. nov., discovered at a post-mining site, has four segmental pyriform glands, an oesophageal appendage restricted to segment V, a clitellum with distinct transverse rows and dorsal and ventral interruption, and spermathecae with blossom-like fields of vesicular gland cell apices around the ventrally located ectal pores. The species is without peculiar characters but the combination of characters is diagnostic. Its morphological distinction from A. nurmineni, described from the Indian subcontinent, is difficult due to the poor description of that species; A. nurmineni is therefore considered a species inquirenda. Achaeta gemmata sp. nov., discovered in high abundance at a post-fire site, is without pyriform glands but with conspicuous, gem-like lateral papillae in all preclitellar segments. The papillae are modified and enlarged epidermal gland cells that protrude into the body cavity. The species is without oesophageal appendage and has a dorsally closed clitellum and lateral spermathecal pores. It is superficially similar to Achaeta camerani, found at the same site, but can be distinguished based on sexual and non-sexual characters. A comparison of COI sequences showed 100% identity with a specimen from Sweden, erroneously identified as A. cf. brevivasa. Genetic distance between the two new species based on COI differences is 20%, distances to other species of Achaeta with publicly available COI sequences range from 16% to 26%.

“…Some nomenclature changes proposed therein, however, are not adopted here because they appear unjustified, e.g. the relegation of some species to junior synonyms or nomina dubia (see Rota 2015), or the lumping of distinct lineages into imprecisely diagnosed taxa ( Cognettia sphagnetorum ; see Martinsson et al 2014). …”

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education.This paper provides updated information on the taxonomic composition and distribution of the Annelida - terrestrial Oligochaeta (Megadrili and Enchytraeidae), Aphanoneura and Polychaeta, recorded in Europe. Data on 18 families, 11 autochthonous and 7 allochthonous, represented in our continent by a total of 800 species, are reviewed, beginning from their distinctness, phylogenetic status, diversity and global distribution, and following with major recent developments in taxonomic and faunistic research in Europe. A rich list of relevant references is appended. The Fauna Europaea Annelida - terrestrial Oligochaeta data-set, as completed in 2004, will be updated accordingly.

Enchytraeid worms collected in South Africa and on the Marion, South Orkney, South Georgia and South Shetland Islands during 2008–2015 were studied using morphology and seven genetic markers. Nine species were recognized: one terrestrial (Christensenidrilus blocki) and all the others marine littoral (five Lumbricillus and three Marionina s.s.). An estimated phylogeny including other enchytraeids from the Northern Hemisphere, many of which are members of Lumbricillus and some representing Marionina s.l., confirmed a non-monophyletic Lumbricillus, with some of its current species closely related to Grania or Marionina s.s. The phylogeny also corroborated a non-monophyletic Marionina s.l., with Marionina s.s. closely related to Grania and Lumbricillus s.l., but not to the remaining sequenced ‘Marionina’ or to Ch. blocki. These results provide a long-needed starting point for a revision of both Marionina and Lumbricillus. We provide morphological descriptions of all nine species, three of which are new to science: Lumbricillus finisafricae sp. nov., Lumbricillus nivalis sp. nov., and Marionina fusca sp. nov. Comments on three related species of Marionina s.s. based on re-examined type material are also provided.
