Although Batillipes is the most numerous and widespread arthrotardigrade genus (Kristensen & Mackness 2000;Degma et al 2009Degma et al -2014, this study shows that there are many non-investigated areas in the well-explored Baltic Sea which could yield new records.…”

The tardigrade fauna of Poland is one of the better known in Europe. However, almost all studies have been carried out on the limno-terrestrial species, while marine Tardigrada have been neglected. To the best of our knowledge only one report on marine Tardigrada for Polish waters has been published up to now. In the present study the first records of two marine arthrotardigrade species, Batillipes mirus and Batillipes noerrevangi, from Puck Bay (Baltic Sea) are reported. The lowest salinity value in the study area was 3-4 PSU, and B. noerrevangi should be considered the most brackish water-tolerant arthrotardigrade. Samples were collected from the vegetated seabed (seagrass and macrophytes) and the bare sandy bottom in different seasons. A single specimen of B. mirus was found only during the autumn campaign. Specimens (adults and larval stages) of B. noerrevangi were found in all samples during spring, summer and autumn campaigns. Additionally, morphometric data with detailed microphotographs of B. noerrevangi (PCM, DIC) and B. mirus (PCM) as well as a discussion of the new records are presented. The validity of the occurrence of B. dicrocercus in Poland, which was determined based on a single larva from the Międzyzdroje area by Hummon, is also discussed. The larva from Międzyzdroje should be regarded as an undetermined species; thus, the marine tardigrade fauna from Poland consists of only the two newly recorded species.

“…Originally, species of Renaudarctus and Neostygarctus were considered to be members of the same family, the Renaudarctidae, (Kristensen and Higgins 1984) because they are the only two genera possessing feet with digits, as well as dorsal cuticular (and now also ventral) plates. However, these characters are also present in the newly described genus and species Prostygarctus aculeatus Rubal et al 2013. As indicated in Caudal view.…”

The tardigrade fauna of Condor Seamount, west of the Azores, is relatively rich, and species from at least seven genera are represented. A new species of the rare marine genus Neostygarctus (Arthrotardigrada) was found at 206 m depth at the summit of the seamount. This is the first record of the genus from the Atlantic Ocean, and also the deepest record of the genus. The new species Neostygarctus oceanopolis sp. nov. is easily distinguished from the Mediterranean type species N. acanthophorus by the number of middorsal spines. N. acanthophorus has five dorsal spines, whereas the adult of N. oceanopolis sp. nov. has seven. The cave tardigrade from Japan, Neostygarctus lovedeluxe also has dorsal spines on all five segments, but only the cephalic and the caudal segments have a middorsal spine, while the three other trunk segments have two spines on each of the dorsal segmental body plates. For the first time, ventral plates are recorded for a species of Neostygarctus. A membranous coating of the all spines of the cephalic segment, the lateral processes of the first three trunk segments, and the spines of the fourth leg pair are unique for Neostygarctus.

“…More recently, Veiga et al (2009) reported the presence of five species of Batillipes: B. pennaki, B. phreaticus, B. dicrocercus, Batillipes sp1 and Batillipes sp2, in two rías in the north of Galicia (Spain). In, Veiga et al (2009), the authors suggest Batillipes sp1 was possibly Batillipes spinicauda D'Addabo, Grimaldi de Zio, 2005 andRubal et al (2013) indicted the possible presence of Batillipes similis Schulz, 1955 in North Portugal. However, these latter identifications require further study before the species are confirmed.…”

“…Studies of marine tardigrades in the Iberian Peninsula are scarce (but see Villora-Moreno and Grimaldi de Zio 1993; Rubal et al 2013). The first record of a Batillipes species was by Rodríguez-Roda (1948), who reported the presence of B. mirus on the Mediterranean coast of Catalonia (Spain).…”

The knowledge of marine tardigrades in the Iberian Peninsula is very scarce in comparison with those from limnoterrestrial environments. As part of an effort to improve the knowledge of marine tardigrades in the Iberian Peninsula, a new species of marine tardigrade, Batillipes minius sp. nov., is described from shallow subtidal coarse sand collected at Moledo, Northern Portugal, close to the mouth of the Minho river. The new species differs from all other Batillipes species by its combination of toe pattern, dorsal and ventral lateral projections, caudal apparatus, cuticle segmentation and the presence of a dorsal indentation in its head. This new species was found in well-oxygenated, shallow subtidal, mediumcoarse sand with low organic matter content.
