We examined external characters and internal anatomy, after dorsal dissection, of 11 species of Oligochaeta from the Peruvian Amazonia Loreto department. Four new species of families Glossoscolecidae and Rhinodrilidae and genera Righiodrilus and Martiodrilus are described here. Righiodrilus omagua, sp.

The Eisenia nordenskioldi complex is known for its high karyotype diversity and morphological type, and there are many cryptic species present in this complex. The species is widely distributed in the Palearctic biogeographic region including Northeast China. However, the taxonomy of this species complex remains inadequately defined.

Two acanthodriline new species from the states of Tabasco and Chiapas in southern Mexico are described, Diplotrema chajulensis sp. nov. and Lavellodrilus sheylae sp.nov. Diplotrema chajulensis sp. nov. has spermathecae where the ampulla inserts at a right angle from the duct and the diverticulum continues the main axis; it is distinguished from other ...

The amazon forest is the habitat of a high species diversity of invertebrates and unfortunately the real richness had been underestimated. Earthworms’ inventories had been poor because difficult to describe new species. This study adds new records to eastern amazon of two new species belong Rhinodrilus and Andiorrhinus genera. R. priscilae n. sp.

Several new earthworm species have been described in France in the last decade, but the Western peri-Alpine region, despite hosting several endemic species, has received little attention. A recently discovered earthworm species from this region was found to be a close relative to Avelona ligra and Allolobophora s.l. zicsii after molecular phylogenetics

AbstractMolecular phylogenetics contributes to making important advances in the challenging field of earthworm taxonomy. Use of this type of analysis has enabled clarification of the phylogenetic relationships between early-branching genera of Lumbricidae within the highly diverse Franco-Iberian realm.

AbstractThe earthworm genus Helodrilus comprises about 20 species with distributions ranging from the Iberian Peninsula to the Caucasus, through Central Europe, the Balkans, Anatolia and the Levant. The species prefer moist habitats and are often found in the mud of river banks, in swamps or in caves. Although a high degree of morphological variability

Relationships among, and content of, earthworm families have been controversial and unstable. Here we analyse molecular data from 14 Crassiclitellata families represented by 54 genera, the non-crassiclitellate ‘earthworms’ of the Moniligastridae, plus several clitellate outgroups.
