Actual checklist of Tardigrada species
No full textMore than one thousand Tardigrada species were included in the published checklist (Guidetti, R. & Bertolani, R. 2005. Tardigrade taxonomy: an updated check list of the taxa and a list of characters for their identification. Zootaxa, 845, 1–46.) plus the additions and corrections to this checklist (Degma, P. & Guidetti, R. 2007. Notes to the current checklist of Tardigrada. Zootaxa, 1579, 41–53.). For practical reasons, we have joined these two papers (without comments added to particular taxa as well as without references published in these papers) into an accurate combined version of the checklists. We incorporated all taxonomical novelties in the current edition of the Checklist even if they were published just online. Then, following the International Code of Zoological Nomenclature, we corrected the year of a taxon description in its print edition. This checklist is free for all users, but utilization of it requires the citation of the two original papers. This checklist is the platform for occasional upgrades (date of latest upgrade is in the title). The changings respect to the previous version of the checklist have yellow background.
If you also use these changes, please also cite this checklist (Degma, P. & Guidetti, R. Actual checklist of Tardigrada species. DOI: 10.25431/11380_1178608. Accessed date).
This checklist collects the taxonomic and systematic information available in the bibliography, so the authors do not necessarily share what is reported in the articles used for the composition of this list.
Currently there are 35 families, 164 genera, 1508 species and 16 additional subspecies/forms included in the checklist.
Please write us if you find any mistake or missing data in this checklist. Your help in its improvement will be acknowledged

Eohypsibiidae R. Bertolani & Kristensen 1987
No full textEOHYPSIBIIDAE R. Bertolani & Kristensen, 1987 <p> (<i>nomen novum</i> for Amphibolidae Bertolani, 1981 in Bertolani & Kristensen, 1987)</p> <p> Eutardigrades without cephalic papillae. Diploclaws similar in the shape and size arranged asymmetrically with respect to the median plane of the leg (conventionally described as: 2121). Claws of the <i>Eohypsibiidae</i> type (= <i>Bertolanius</i> type) are divided into three distinct sections, basal section, secondary branch and primary branch, sequentially arranged and separated by obvious septa (Figs. 1 D, 9A).The primary branch is rigidly joined to the secondary branch. The internal claws can rotate on their base by 180°; this rotation may lead to a symmetric arrangement of the claws which confuses the real asymmetric arrangement.</p> <p> Two models of bucco-pharyngeal apparatuses can be recognized within the family: the <i>Bertolanius</i> model and the <i>Eohyspibius</i> model.</p> <p> The <i>Bertolanius</i> model (Fig. 9 B)</p> <p>Tube rigid without ventral lamina; apophyses for the insertion of the stylet muscles in the shape of "ridges" symmetrical with respect to the frontal plane; caudal processes of both these apophyses pointing backwards and sideways. Peribuccal lamellae (14) present; peribuccal papulae absent.</p> <p> The <i>Eohypsibius</i> model (Fig. 9 C)</p> <p>Tube subdivided into an anterior, rigid portion (buccal tube) without ventral lamina, and a posterior flexible portion (pharyngeal tube) with a spiral thickening; no cuticular thickening is present between the buccal tube and the pharyngeal tube in the known species. Apophyses for the insertion of the muscles of the stylets form "wingshaped ridges" symmetrical with respect to the frontal plane; caudal processes of both these apophyses pointing backwards and sideways. Peribuccal lamellae (14) present.</p> <p>This type of bucco-pharyngeal apparatus has some characteristics of the Itaquasconinae model (Hypsibiidae), but it is very different from all the known variants of that model in the shape of the apophyses for the insertion of the stylet muscles, in the presence of peribuccal lamellae (Bertolani & Kristensen, 1987), and in the shape of the stylet furcae (Pilato & Binda, 1996b).</p> <p> <b>Composition:</b> Two genera, <i>Bertolanius</i> and <i>Eohypsibius,</i> are ascribed to the family.</p> <p> A third genus, <i>Fujiscon</i> Ito, 1991, was ascribed to the family Eohypsibiidae, but in our opinion it is not valid. As stated by Pilato & Binda (2003), the claws of <i>Fujiscon</i> are not of the <i>Eohypsibius</i> type (basal portion, secondary branch and primary branch are not exactly sequentially arranged; the primary branch is joined to the secondary branch by a flexible connection); in addition the two claws of the same leg are very different from one other, and the internal claw cannot rotate on its base. The claws of <i>Fujiscon</i> are basically of the <i>Hypsibius</i> type but with septa separating the basal section, secondary branch, and primary branch. Pilato & Binda (2003) remarked that septa are present in others species attributed to other genera (<i>e.g., Diphascon, Isohypsibius, Acutuncus</i> and others).They also noted that in some species individual specimens may have claws both with and without septa, <i>e.g.,</i> in <i>Isohypsibius elegans</i> Binda & Pilato, 1971 and in <i>Acutuncus antarcticus</i> (Richters, 1904). Therefore the presence and the degree of septa development in the claws must be considered as variable characters, and not significant at the genus level.</p> <p> In conclusion, the genus <i>Fujiscon</i>, in our opinion, is not valid and we do not take it into consideration in this paper.</p>Published as part of <i>Pilato, Giovanni & Binda, Maria Grazia, 2010, Definition of families, subfamilies, genera and subgenera of the Eutardigrada, and keys to their identification, pp. 1-54 in Zootaxa 2404</i> on page 18, DOI: <a href="http://zenodo.org/record/194138">10.5281/zenodo.194138</a>
