Extensive cryptic diversity in the cosmopolitan sludge worm Limnodrilus hoffmeisteri (Clitellata, Naididae)

Limnodrilus hoffmeisteri Claparède, 1862 is a common freshwater worm, often regarded as an indicator of organic pollution. The taxonomic status of this species is controversial due to great variation in morphological features. Numerous morphological …

Barcoding gap, but no support for cryptic speciation in the earthworm Aporrectodea longa (Clitellata: Lumbricidae)

DNA-barcoding, using the mitochondrial marker COI, has been found successful for the identification of specimens in many animal groups, but may not be suited for species discovery and delimitation if used alone. In this study, we investigate whether …

Cryptic speciation and limited hybridization within Lumbricus earthworms (Clitellata: Lumbricidae)

Cryptic mitochondrial (mt) lineages are known to exist in the earthworm morphospecies Lumbricus rubellus and L. terrestris. The latter was recently split into two species, L. terrestris and L. herculeus, based on large genetic distances and a …

Ny snigelkott på Västkusten

I Sverige finns ett 90-tal arter av nakensnäckor, som hör till gruppen Opisthobranchia – bakgälade snäckor. En ny genetisk studie visar att den vanliga arten snigelkott faktiskt består av två arter.

Phylogeny and species delimitation of North European Lumbricillus (Clitellata, Enchytraeidae)

The enchytraeid genus Lumbricillus comprises about 80 described species of clitellate worms, which are up to a few centimetres long, and they mostly inhabit the littoral zone of nontropical marine and brackish waters world-wide. The phylogeny of this …

Morphological and genetic characterization of the first species of Thalassodrilides (Annelida: Clitellata: Naididae: Limnodriloidinae) from Japan

A species of marine limnodriloidine oligochaete, Thalassodrilides cf. briani Erséus, 1992, is recorded from gravelly sand sediments of the subtidal zone in Ehime Prefecture, Japan. The present material agrees with the original description of T. …

Annotating public fungal ITS sequences from the built environment according to the MIxS-Built Environment standard – a report from a May 23-24, 2016 workshop (Gothenburg, Sweden)

Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building …

A case of total absence of yellow in the Golden Whistler Pachycephala pectoralis

An aberrantly coloured male Golden Whistler Pachycephala pectoralis, lacking yellow pigment, is reported from the Bellarine Peninsula, Victoria. This could be the first documented case of this colour aberration in the species.

Mitochondrial evidence supports a Nearctic origin for the spreading limicolous earthworm Sparganophilus tamesis Benham, 1892 (Clitellata, Sparganophilidae)

Comment on the proposed precedence of Cognettia Nielsen & Christensen, 1959 over Euenchytraeus Bretscher, 1906 and Chamaedrilus Friend, 1913 (Annelida, Oligochaeta, ENCHYTRAEIDAE) (Case 3689; see BZN 72: 186–192)

We analysed samples of Sparganophilus taken at the corners of its distribution area in Europe (UK, Germany and Italy). No mitochondrial genetic divergence within and amongst them was found, neither in COI nor in 16S. Further, the COI haplotype was …
