“…These organisms, annelid worms (Annelida: Oligochaeta: Enchytraeidae), belong to the soil mesofauna, in which they play important roles, either located in natural or agricultural environments (Pelosi & Römbke, 2016; Van Capelle et al, 2012). Most research has taken place in Europe, although enchytraeids are also abundant in Brazilian agroecosystems (Demetrio et al, 2020; Niva et al, 2015), and include some studies in other countries like Argentina (Lopez et al, 2005; Romero, 2019), Korea (Dózsa‐Farkas et al, 2018), Antarctica (Lee et al, 2019) and others. Enchytraeidae assessment has been proposed as a monitoring tool for the biological quality of soil (Bispo et al, 2009); as such, enchytraeids are recognized as sensitive bioindicators with regard to changes in soil pH (Didden & Römbke, 2001) as well as management and use, being more abundant in soils with an intermediate level of disturbance (Pelosi & Römbke, 2016, 2018; Van Capelle et al, 2012).…”

The relationship between the productivity of crops of agricultural interest and their interactions with physicochemical soil properties is widely explored. However, there is still a gap concerning the contribution of biological soil attributes and especially the relationship between crop productivity and the structures of organism communities within the soil, such as the enchytraeids. This paper aimed to evaluate the diversity and structures of enchytraeids communities in subtropical soils and their relationship with soybean productivity and soil properties within a no‐tillage system. This study was conducted in soybean growing grounds working under no‐till farming systems in southern Brazil. Samples were collected according to ISO 23611‐3 and extracted with the hot–wet methodology. The organisms were identified up to their genus level. Enchytraeids density increased with the increase of soybean productivity for both evaluated crops. Enchytraeus, Fridericia, and Hemienchytraeus were more abundant in high productivity and genus Achaeta was only found in the second crop and was not a sensitive indicator toward changes in soybean productivity. Regarding the relationship between the enchytraeid community and soil attributes, the variables clay, phosphorus, moisture contents, pH, Ca/Mg as well as carbon and nitrogen from soil and litter, affected Enchytraeidae distribution. Enchytreids showed significant correlations with soybean productivity in the no‐tillage system for subtropical soils in Brazil, demonstrating potential bioindicators of soil quality and consequently of soybean productivity.

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.
