Meiofauna sampling in the proximity of Syd-Hällsö Island (Strömstad, Sweden) revealed a new species Kinorhyncha from Skagerrak. The species, Setaphyes elenae sp. nov., is distinguished its congeners by arrangement middorsal cuticular specializations (it has shortened, distally rounded processes on segments 1 and 9 elevations throughout 2–8), as well presence paired laterodorsal setae 3, 5, 7 ventromedial 5 both males females. finding north-eastern Atlantic Ocean, provides valuable...
Abstract Aethozoid ctenostome bryozoans are an unusual, small group of solitary bryozoans, occurring almost exclusively in deep-sea habitats. Currently, there only five species belonging to four, still insufficiently known genera, which have been reported from the Atlantic and Pacific Oceans. Recent examination sediment core samples active volcanic area near Mayotte revealed a high abundance aethozoids, recorded for first time Indian Ocean. A comparative approach identified specimens as new...
Abstract Nematodes typically comprise the most abundant phylum in meiofaunal communities. We aim to characterize specific ecological conditions that influence Nematoda communities Posidonia oceanica grasslands focusing on three habitats: leaves, matte, and unvegetated adjacent sediment. hypothesized constant flux of nutrients under canopy would result a higher concentration metazoans compared sediment outside; however, hypothesis was not confirmed by obtained results. The habitat...
Abstract Polymetallic nodule fields represent a large reservoir of undiscovered biodiversity that becomes particularly evident for meiobenthic organisms, the smallest-sized faunal group. Knowledge gaps are especially noticeable generally low-density metazoan groups, such as Kinorhyncha, so-called mud dragons. Using both morphological and genetic (metabarcoding) approaches, we provide general overview comparison diversity kinorhynchs collected during nine sampling campaigns (2016–2019)...
Taxonomic studies of the phylum Kinorhyncha follow a standardised structure, which is extremely useful in many aspects, such as making it easier to read and compare different species descriptions. Nevertheless, morphological measurements methods, essential for formal description species, may differ according authors. In present contribution, we propose method taking representing measurements, with aim obtaining comparable repeatable morphometric results. Additionally, an online repository...
Abstract A new species of the cyclorhagid genus Meristoderes is described. zmaj sp. n. distinguished from its congeners by unique arrangement spines and tubes. It possesses acicular on segments 4, 6 8 in middorsal position 6–9 lateroventral position; tubes segment 2 subdorsal, midlateral ventrolateral position, 5 10 laterodorsal position. With formal description M. n., number within increased to 10. In addition, appearance a accompanying fauna North-Eastern Adriatic Sea fauna, extensively...
The kinorhynch fauna from Portugal has been explored, yielding a new species of the genus Setaphyes (Kinorhyncha: Allomalorhagida). This is first description an allomalorhagid Portugal. Specimens were collected at subtidal muddy beach in Alvor, village located southernmost region algarvensis sp. nov. may be distinguished its congeners by unique arrangement setae: paired paradorsal setae on segments 2–7 and 9, seta segment 8 unpaired, laterodorsal 2–3 6–9 males 2–9 females, paralateral 1,...
Six of the eight species genus Setaphyes have been described from Europe. In present contribution, European are revised and two them, S. dentatus (Reinhard, 1881) kielensis (Zelinka, 1928), redescribed following current approaches Kinorhyncha taxonomy. For this purpose, material 17 localities throughout Atlantic Ocean Mediterranean Black Seas was investigated. The redescriptions most common pycnophyid in Europe include detailed information on intraspecific variation among populations. is...
A new species of Mixtophyes Sánchez et al. 2014 is described from the Clarion-Clipperton Fracture Zone (north-eastern Pacific Ocean). The characterised by presence spinose processes on segments 1-11 in middorsal position and 1-10 midlateral position, paired paradorsal setae 2, 4-6 8-9, unpaired ones 3 7, paralateral ventrolateral positions 2-9. In addition, some morphological characteristics family Neocentrophyidae genus are discussed, diagnoses both taxa updated. Lastly, taxonomic...
Specimens of two species Kinorhyncha, Setaphyes dentatus and S. kielensis, were collected in 1988, 1998, 2016 at intertidal sites on the island Sylt, North Sea, investigated as preserved material by light microscopy scanning electron for their epibionts. One Acinetidae (Suctoria), one Vaginicolidae (Peritrichia), bacteria traced. The most abundant ciliate with 705 specimens was Trematosoma husselae sp. nov. occurring 1–46 a basibiont, mainly ventral side here especially segment 1. Cothurnia...
La Colección de Invertebrados es una las 17 colecciones científicas del Museo Nacional Ciencias Naturales Madrid (MNCN-CSIC). Hasta la fecha, dicha colección comprendía ejemplares pertenecientes a 27 filos animales. El presente trabajo informa donación 44 25 especies, 13 géneros y seis familias filo Kinorhyncha, lo que amplía hasta 28 el número representados en citada colección. Para cada especie se aportan datos lugar, fecha proyecto procedencia. Además, reporta por primera vez Pycnophyes...
