The species was found at three subtidal stations in the Schelde estuary in Belgium, where it was probably introduced from the Americas. We provide an overview of the species’ nomenclature, diagnostics, distribution, and ecology. Bratislavia dadayi is one of 11 non-indigenous annelids currently known to occur in the Schelde estuary. Key words: alien species; Annelida; Clitellata; Oligochaeta; Polychaeta; Belgium Introduction Annelids, and oligochaetes in particular, are a less-studied group, often overlooked when Over the last 150 years, the number of non- considering alien species. Yet the best studied native species turning up in areas far from their Annelid species, Lumbricus terrestris (L., 1758), original range has increased significantly (Bax et is now considered a widespread invasive species al. -
Detailed Reconstruction of the Nervous and Muscular System Of
Kerbl et al. BMC Evolutionary Biology (2015) 15:277 DOI 10.1186/s12862-015-0531-x RESEARCH ARTICLE Open Access Detailed reconstruction of the nervous and muscular system of Lobatocerebridae with an evaluation of its annelid affinity Alexandra Kerbl1, Nicolas Bekkouche1, Wolfgang Sterrer2 and Katrine Worsaae1* Abstract Background: The microscopic worm group Lobatocerebridae has been regarded a ‘problematicum’, with the systematic relationship being highly debated until a recent phylogenomic study placed them within annelids (Curr Biol 25: 2000-2006, 2015). To date, a morphological comparison with other spiralian taxa lacks detailed information on the nervous and muscular system, which is here presented for Lobatocerebrum riegeri n. sp. based on immunohistochemistry and confocal laser scanning microscopy, supported by TEM and live observations. Results: The musculature is organized as a grid of longitudinal muscles and transverse muscular ring complexes in the trunk. The rostrum is supplied by longitudinal muscles and only a few transverse muscles. The intraepidermal central nervous system consists of a big, multi-lobed brain, nine major nerve bundles extending anteriorly into the rostrum and two lateral and one median cord extending posteriorly to the anus, connected by five commissures. The glandular epidermis has at least three types of mucus secreting glands and one type of adhesive unicellular glands. Conclusions: No exclusive “annelid characters” could be found in the neuromuscular system of Lobatocerebridae, except for perhaps the mid-ventral nerve. However, none of the observed structures disputes its position within this group. The neuromuscular and glandular system of L. riegeri n. sp. shows similarities to those of meiofaunal annelids such as Dinophilidae and Protodrilidae, yet likewise to Gnathostomulida and catenulid Platyhelminthes, all living in the restrictive interstitial environment among sand grains. -

They impact soil properties and nutrient cycling, shaping plant community composition and aboveground food webs. The simplicity of the earthworm body plan has hampered morphology-based classifications and taxonomy; hence current research on Lumbricidae systematic relies mostly on molecular data from multiple or single locus [e.g., cytochrome oxidase subunit I (COI) barcodes] to infer evolutionary relationships, validate taxonomic groups and/or identify species. Here we use multiple nuclear and mitochondrial gene regions (including COI) to generate updated maximum likelihood and Bayesian phylogenies of the family Lumbricidae. We then compare these trees to new COI trees to assess the performance of COI at inferring lumbricid inter-generic relationships. -
