... Among them, only one species belonging to this family has ever been described from Namibian waters, Ninoe desbruyeresi Miura, 1980 (see Day, 1967;Miura, 1980;Read & Fauchald, 2022). Considering that over the last two decades alone six new genera have been erected and more than 40 new species described globally within Lumbrineridae (Aguirrezabalaga & Carrera-Parra, 2006;Cai & Li, 2011;Carrera-Parra et al., 2011;Martins et al., 2012;Arias & Carrera-Parra, 2014;D'Alessandro et al., 2014;Kurt-Sahin et al., 2016;Katsiaras et al., 2018;Borisova & Budaeva, 2020;Borisova & Budaeva, 2022), at least four of which belong to Ninoe (Carrera-Parra, 2001;Hernandez-Alcantra et al., 2006), the diversity within this region may be underestimated. Further, exploitation of mineral resources, especially the extraction of diamonds off southern Namibia, continues to reveal species that cannot be identified using local or regional guides thereby highlighting the limited research conducted in describing faunal communities in this region and the anticipation that many more undescribed species may be found (see Glasby & Alvarez, 1999;Hutchings & Kupriyanova, 2018;Simon et al., 2022). ...
Despite an increase in the number of new lumbrinerid descriptions globally and over recent decades, no new lumbrinerid species have been described from southern Africa over the last 40 years. This suggests that species richness in the region is currently underestimated, and that continued research would result in the discovery of more undescribed species. Here, a new species is described from grab samples collected off southern Namibia at >100 m depth. Ninoe namibiensis sp. nov. is characterized by simple multidentate hooded hooks with a long hood that only appears after chaetiger 18, branchiae from chaetiger 1–2 to 38 (with up to 7 filaments) and maxillary apparatus: MX III with one prominent tooth followed by a knob and MX IV unidentate with finely denticulate cutting edge (11 small teeth). A key to the Ninoe from southern Africa is provided.

A compilation of polychaete species distributed along the East coast of India has been presented in this paper, which
includes a total of 22 species belonging to 20 genera, 15 families, four orders and three subclasses; obtained during
the summer monsoon survey of 2013. Subclass Errantia and Sedentaria comprised of 10 species each, while subclass Polychaeta incertae sedis consisted of only two species.
... It has been shown that some species of Lumbrineris and Gallardoneris prefer areas enriched with organic matter [303,311,312]. Kuwaita hanneloreae Arias and Carrera-Parra, 2014 was reported from a fine to medium sand with a mean organic matter content of 1.68%, reaching densities over 4-5 ind/m 2 and occurring together with other lumbrinerids, Scoletoma impatiens and Lumbrineris latreilli [313]. ...

In southwest Spain (Cádiz), sold specimens of S. impatiens are harvested in northwest Spain [356]; in the Canary Islands, Lumbrineris latreilli is a highly appreciated bait used by experienced fishers [357]. In northern Spain, Kuwaita hanneloreae, S. impatiens, and L. latreilli are highly appreciated as fishing bait and constitute an important natural resource from this area [313]; however, dermatitis problems have been documented when handling the latter species [358]. In Japan, Kuwaita heteropoda (Marenzeller, 1879) is commonly used as bait by Japanese fishers who observed that certain carnivorous insects die when they settle upon the worm. ...
In this study, we analyze the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation. Eunicida is an order of Errantia annelids characterized by the presence of ventral mandibles and dorsal maxillae in a ventral muscularized pharynx. The origin of Eunicida dates back to the late Cambrian, and the peaks of jaw morphology diversity and number of families are in the Ordovician. Species richness is heterogeneous among the seven recent families, with more than half of the valid species belonging to the Eunicidae + Onuphidae clade, one of the latest clades to diverge. Eunicidans inhabit soft and hard substrates from intertidal to deep waters in all oceans. The few freshwater species are restricted to Histriobdellidae, a family exclusively commensal/parasite of crustaceans. The reproductive biology, development and ecology of most families are poorly known and the information available suggests low dispersal ability. However, all families have records of widely distributed species. Scrutiny of these wide distributions has often revealed the presence of exotic species or more than one species. The exploration of the deep-sea and of new habitats has led to recent descriptions of new species. Furthermore, the revision of type specimens, the examination of new morphological features and the use of molecular data have revealed hidden biodiversity under unjustified synonyms, poor understanding of morphological features and incomplete descriptions. Molecular studies are still very few or nonexistent for the families Histriobdellidae, Hartmaniellidae, Lumbrineridae and Oenonidae. The integration of new methodologies for morphological and molecular study, along with information on biological and ecological traits appears to be the path to improve the knowledge on the diversity of Eunicida.
... Symptomatic and histologic remission typically occurs with either diet elimination or topical steroid treatment with a response rate of 70-80% with either option [9]. Elemental formulas represent the most effective therapy both in terms of histologic and symptomatic response, with a response rate of > 90% [10]. The empiric elimination diet eliminates foods commonly associated with immunoglobulin E (IgE)-mediated food allergy (typically the top 6 foods which include milk, egg, wheat, soy, fish, and nuts) regardless of allergen test results. ...
Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus associated with an atopic predisposition which appears to be increasing in prevalence over the last few decades. Symptoms stem from fibrosis, swelling, and smooth muscle dysfunction. In the past two decades, the etiology of EoE has been and is continuing to be revealed. This review provides an overview of the effects of genetics, environment, and immune function including discussions that touch on microbiome, the role of diet, food allergy, and aeroallergy. The review further concentrates on the pathophysiology of the disease with particular focus on the important concepts of the molecular etiology of EoE including barrier dysfunction and allergic hypersensitivity.
... The Lumbrineridae has been widely studied worldwide, which gave rise to several new species and new records recently discovered (e.g. Aguirrezabalaga & Carrera-Parra 2006;Carrera-Parra 2006a,b, 2009Martins et al. 2012;Arias & Carrera-Parra 2014;Bertasi et al. 2014;D'Alessandro et al. 2014;Gómez et al. 2015). Now, at least 13 genera with more than 200 valid species are recognised worldwide (Carrera-Parra 2006a,b;Carrera-Parra et al. 2011;Martins et al. 2012). ...
The present study is a part of a larger project aiming to characterise the benthic macrofaunal assemblages from the Gulf of Milazzo (Southern Tyrrhenian Sea, Central Mediterranean). Forty-eight samples from 16 sites were collected during the summer of 2010 by means of van Veen grab (0.1 m2) at 20 and 50 m depths to characterise taxonomically, ecologically and biogeographically the present species of Lumbrineridae. Sandy-silt mixed sediments characterised the study area. Abyssoninoe hibernica and Lumbrineris luciliae are newly recorded for the Mediterranean Sea, and Gallardoneris iberica, Lumbrineris geldiayi and Lumbrineris lusitanica are new records for the Central Mediterranean Sea. Therefore, a total of 29 species of Lumbrineridae are currently present and recognised on Mediterranean coasts. Additionally, we provide an updated key to the Mediterranean species of the family.
... Family Lumbrineridae Schmarda, 1861 are polychaetes widely distributed in muddy and sandy bottoms of continental shelves and intertidal coastal areas, with more than 200 valid species being recognized worldwide (Carrera-Parra, 2006a), 24 of them in the Iberian coasts (Martins et al., 2012b), including the most recent species described for the north of Spain, Kuwaita hanneloreae Arias & Carrera-Parra, 2014.

Several new genera and species within Family Lumbrineridae have been erected or described worldwide in this century (e.g. Carrera-Parra, 2001a, b, 2006aAguirrezabalaga & Carrera-Parra, 2006;Hernández-Alcántara et al., 2006;Carrera-Parra et al., 2010;Cai & Li, 2011a, b;Martins et al., 2012b;Arias & Carrera-Parra, 2014;D'Alessandro et al., 2014). The Mediterranean Sea is not an exception, where several polychaete species have been first reported, most of them classified as non-indigenous (NIS) and thus representing a potential threat for endemic species (Coll et al., 2010). ...
... The recent taxonomic effort allowed also the creation or update of several taxonomic keys appropriate to the Iberian Peninsula macrofauna (e.g. Aguirrezabalaga & Carrera-Parra, 2006;Pires et al., 2010;Ravara et al., 2010;Martins et al., 2012bMartins et al., , c, 2013aArias & Carrera-Parra, 2014). The major novelties of this study are the increase to 25 in the number of known lumbrinerid species in the entire Iberian Peninsula as well as providing an updated taxonomic key for the Family Lumbrineridae for the Iberian waters (adapted from Martins et al., 2012b), including now the recent new species recognized in the north of Spain, K. hanneloreae, and the new record in the Iberian Peninsula, A. bidentata, as follows: Ramos (1976) recorded L. acuta from Spain and described MI without accessory teeth; however, L. acuta (originally described from Rhode Island, USA) has MI with one accessory tooth (Perkins, 1979 ...
Lumbrinerids are amongst the most abundant and diverse polychaete families in worldwide continental shelves, and have received attention recently through the description of several new species and new occurrences. Herein, a total of four lumbrinerid species are firstly reported in the eastern and southern Spanish continental shelf, extending their biogeographic distribution to the western Mediterranean Sea and increasing up to 25 the number of species known in the Iberian Peninsula coasts. New insights on taxonomy, ecological and biogeographic preferences and an updated taxonomic key for Iberian coasts and surrounding areas are also provided.

Lumbrineriopsis dulcis sp. nov. is morphologically described from the continental shelf and slope of Espírito Santo and the Campos Basin of Rio de Janeiro state, southeastern Brazil, at depths between 14 and 400 m. Lumbrineriopsis mucronata is the only species of the genus recorded until now in Brazil. The new species differs from other congeneric species in its jaw-apparatus morphology with unfused mandibles and a fixed number of simple limbate chaetae and simple, bidentate, hooded hooks in each parapodium. This paper aims to fill the gap in knowledge on the family Lumbrineridae, which has not been studied in Brazil for the last 25 years and provides the first record of the genus from Espírito Santo and Rio de Janeiro states. This record is significant given the damage to the marine ecosystem of the Espírito Santo region due to the 2015 rupture of the Samarco mining company dam, the largest environmental disaster in Brazil’s history. In addition, this region has important environmental conservation units such as Costa das Algas Environmental Protection Area, Santa Cruz Wildlife Refuge, and Comboios Biological Reserve. All these preserved areas are of paramount importance for the protection of marine biological diversity.
The small Lumbrineridae Gallardoneris iberica Martins, Carrera-Parra, Quintino & Rodrigues, 2012 was first described as new to science based on specimens from Portuguese waters. Then, it was successively reported from several south European areas, including Spain, Italy, Greece, and Cyprus. Here evidence is presented that G. iberica should be placed in synonymy with Lumbrineris nonatoi Ramos, 1976, originally described from NW Mediterranean waters, a species that fits with the diagnosis of Gallardoneris . Based on specimens from the French coasts of the NW Mediterranean, this paper (1) redescribes the species using the new combination Gallardoneris nonatoi (Ramos, 1976) and (2) provides a morphometric analysis of its main morphological characters. The lack of recent reports of G. nonatoi comb. nov. in Mediterranean waters is presumably due to the recent redescription of the species as L. nonatoi based on specimens from the Gulf of Mexico. However, these specimens belong to Lumbrineris , as currently defined. By assessing their morphological differences, it is concluded that the specimens from the Gulf of Mexico represent a different and new species, namely Lumbrineris jan sp. nov. Also discussed is the possible assignation of Lumbrineris longipodiata Cantone, 1990, a poorly known species seldom recorded since its original description from the Gulf of Catania (Mediterranean Sea) to Gallardoneris , as well as on whether it is a valid species or may be an additional junior synonym of G. nonatoi comb. nov.
