            <p> Subgenus  Hystricochaetonotus Schwank, 1990</p>
            <p>Schwank, P. 1990, Gastrotricha. In: Brauer A. (Ed) Süsswasserfauna von Mitteleuropa. Bd. 3/ 1: 1–252. G. Fischer Verlag, Stuttgart, p. 217.</p>
            <p> Type species:  Chaetonotus hystrix Metschnikoff, 1865 ; designation by Schwank (1990) </p>
            <p> The subgenus  Hystricochaetonotus was established by Schwank (1990) for the  Chaetonotus species previously included in the ‘group’  spinulosus by Remane (1936). The subgenus has been subsequently accepted by Kisielewski (1997) in its revision of the subgeneric division of the genus  Chaetonotus . The diagnostic features of the subgenus are: a cuticular covering made of three-lobed scales with thick spines, a varying number of which form a dorsal group that can be generally recognized for the considerable length. </p>
            <p> However, the great intraspecific morphological variability of most species, and the existence of species with intermediate features and thus difficult to be clearly assigned to this subgenus rather than to the subgenus C haetonotus s.s., make this character not reliable for diagnostic purpose, even for the type-species (  C. hystrix ). It seems that there is a continuum of the morphological characters putatively fixing the distinction between the subgenera  Hystricochaetonotus and C haetonotus s.s., which seem actually to form a single natural group. Thus  Chaetonotus (Hystricochaetonotus) is synonimized with  Chaetonotus (  Chaetonotus s.s. ) (  syn . nov.) and all the species currently included into it are moved to the latter: </p>
            <p> Chaetonotus (Chaetonotus) hystrix Metchnikoff, 1865 (type species);  C.(C.) acanthophorus Stokes, 1887 ;  C.(C.) aemilianus Balsamo, 1978 ;  C.(C.) anomalus Brunson, 1950 ;  C.(C.) balsamoae Kisielewski, 1997 ;  C.(C.) decemsetosus Marcolongo, 1910 ;  C.(C.) enormis Stokes, 1887 ;  C.(C.) euhystrix Schwank, 1990 ;  C.(C.) ferrarius Schwank, 1990 ;  C.(C.) italicus Balsamo &amp; Todaro, 1995 ;  C.(C.) longispinosus Stokes, 1887 ;  C.(C.) lucksi Voigt, 1958 ;  C.(C.) macrochaetus Zelinka, 1889 ;  C.(C.) murrayi Remane, 1929 ;  C.(C.) novenarius Greuter, 1917 ;  C.(C.) octonarius Stokes, 1887 ;  C.(C.) paucisetosus Marcolongo, 1910 ;  C.(C.) persetosus Zelinka, 1889 ;  C.(C.) polychaetus Daday, 1906 ;  C.(C.) pungens Balsamo, 1990 ;  C.(C.) quintospinosus Greuter, 1917 ;  C.(C.) schlitzensis Schwank, 1990 ;  C.(C.) spinifer Stokes, 1887 ;  C.(C.) spinulosus Stokes, 1887 ;  C. trichodrymodes Brunson, 1950 ;  C.(C.) trilineatus Valkanov, 1937 ;  C.(C.) trispinosus Balsamo, 1990 ;  C.(C.) vargai Rudescu, 1967 , and ten additional marine species. </p>
            <p> Following the inclusion of the subgenus  Hystricochaetonotus in the subgenus  Chaetonotus sensu stricto , the original diagnosis of the latter (Kisielewski 1997, p. 148) is emended as follows: </p>

            <p> Genus  Lepidochaetus Kisielewski, 1991</p>
            <p>Kisielewski J. 1991. Inland-water Gastrotricha from Brazil. Ann. Zool. (Warszawa) 43 (2), p. 10 Typus generis: Lepidochaetus brasilense Kisielewski, 1991; original designation.</p>
            <p> The genus  Lepidochaetus was introduced by Kisielewski (1991) to group some freshwater species previously included in the genus  Chaetonotus , characterized by numerous, rounded, unkeeled scales, provided with long and thin spines covering both the dorsal and the ventral body surfaces. According to Kisielewski’s (1991, 1997) phylogenetic views, this cuticular morphology would be plesiomorphic in the  Chaetonotida . Other more complex morphological patterns would have arisen from this one, generally different on the dorsal and on the ventral body surfaces, as it is the usual condition in the species of genus  Chaetonotus . The latter is a very large genus which includes both freshwater and marine species: Remane (1936) had already divided the genus on morphological criteria into 9 ‘groups’, to only two of which he recognized a subgeneric rank [C. (  Zonochaeta ) and the marine C. (  Halichaetonotus )]. In his systematic revision of the freshwater species, Schwank (1990) divided the genus  Chaetonotus into 8 subgenera (including [C. (  Zonochaeta )], all but one, [C. (Nudichaetonotus)] corresponding to the Remane’s groups. A new subgeneric division of the whole genus  Chaetonotus was then introduced by Kisielewski (1997), who recognized 8 subgenera, accepting those previously created by Schwank except for two [C. (  Bifasciculatella ) and C. (  Diversichaetatella )] and introducing three others: C. (  Primochaetus ), C. (  Captochaetus ) and C. (  Marinochaetus ), the last one entirely marine. </p>
            <p> However, the main morphological features diagnostic of the genus  Lepidochaetus (large kephalion with a free caudal edge, round-rectangular scales with double anterior edge, some dorsal and lateral rear scales with long, straight spines, ventral cuticular covering agreeing in number and character of structures with the dorsal and lateral ones) cannot be unambiguously distinguished from those of the genus  Chaetonotus to which most species of  Lepidochaetus were previously assigned. For this reason  Lepidochaetus should no longer be considered as a separate genus but rather as a subgenus of  Chaetonotus (  syn . nov.). </p>
            <p> Five species were originally included in this genus:  L. brasilense Kisielewski, 1991 ,  L. carpaticus (Rudescu, 1967) ;  L. ornatus (Daday, 1901) ,  L. pusillus (Daday, 1905) ,  L. zelinkai (Grünspan, 1908) . When moved into  Chaetonotus ,  Lepidochaetus brasilense Kisielewski, 1991 becomes  Chaetonotus brasilensis , a secondary junior homonym of  Chaetonotus brasiliensis Schwank, 1990 . We propose here the new name  Chaetonotus brasilianus (nomen novum), as a replacement name for  Lepidochaetus brasilense Kisielewski, 1991 nec Schwank, 1990.  L. pusillus (Daday, 1905) has been successively moved by Kisielewski (1997) into the subgenus  Chaetonotus s.s. and thus is now  Chaetonotus (C.) pusillus (Daday, 1905) . The other 3 species are thus retained in  Chaetonotus (Lepidochaetus) , as  Chaetonotus (L.) carpaticus (Rudescu, 1967) ,  Chaetonotus (L.) ornatus (Daday, 1901) , and  Chaetonotus (L.) zelinkai (Grünspan, 1908) . </p>
            <p> Because of the change from a generic to a subgeneric rank within the genus  Chaetonotus , the original diagnosis of  Lepidochaetus (Kisielewski, 1991, p. 10) is emended as follows: </p>

            <p> The genus  Ichthydium is clearly considered as polyphyletic and thus it is an artificial taxon (Kisielewski,1991). It needs a careful taxonomic revision rather than a division into subgenera based on very few morphological criteria, like the different shape of the furcal tubes and the possible presence of thin dorsal scales on the bare body cuticle. The latter feature is not peculiar of the subgenus I. (Forficulichthys), since cuticular microsculptures and thin scales are occasionally present also in species of the subgenus I. </p>
            <p> (  Ichthydium s. s. ), i.e.  I. podura ,  I. squamigerum . The diagnostic characters of the rare monotypic subgenus  Ichthydium (Pseudichthydium) appear so different from the other  Ichthydium species that they would require a closer examination of the only species known. For all this reasons the subgenera introduced by Schwank (1990) have not been introduced in the present list. </p>

            <p> Typus generis:  Lepidoderma punctatum Greuter, 1917 ; original designation by Schwank (1990) as  Rhomballichthys punctatus . </p>
            <p> Schwank (1990) introduced the genus  Rhomballichthys for three freshwater species with a complete cuticular covering of rhombic, unpedunculated scales, smooth or keeled, and with a very short, minute spiny process. These features combine those of three different genera (  Aspidiophorus ,  Lepidodermella ,  Heterolepidoderma ). Scale shape and habitus of the species remind the species of  Aspidiophorus , which all have pedunculated scales. On the other hand, the  Lepidodermella species have smooth scales and the  Heterolepidoderma species have numerous, small, elliptical, generally keeled, unpedunculated scales. The typus generis of  Rhomballichthys ,  R. punctatus (Greuter, 1917) is a species whose taxonomical position has been long debated: it was assigned to either  Aspidiophorus or  Lepidodermella and it was finally place into the latter genus due to the presence of unpedunculated, smooth scales, even if provided with a very short spiny extension (Balsamo 1983).  Rhomballichthys murrayi is a new name introduced by Schwank (1990) for  Chaetonotus sp. Murray, 1913: the original description of this species is quite incomplete and does not allow to define with certainty its morphological characters, so that it is a species inquirenda. Finally,  Rhomballichthys carinatus is a new name introduced by Schwank (1990) for the specimens of  Heterolepidoderma fallax Remane, 1936 reported by Roszczak (1969) from Poland. Schwank considered these ones as belonging to a different species from  Heterolepidoderma fallax Remane, 1936 , that he includes among the species inquirendae. The assignment of the Polish specimens to a new species should require a careful revision of the distinctive characters:  Rhomballichthys carinatus is considered here as a species inquirenda. The genus  Rhomballichthys is maintained as a monotypic genus only including  R. punctatus (Greuter, 1917) . </p>

            <p>Schwank, P. 1990, Gastrotricha. In: Brauer A. (Ed) Süsswasserfauna von Mitteleuropa. Bd. 3/ 1: 1–252. G. Fischer Verlag, Stuttgart, p. 45.</p>
            <p> Type species:  Dasydytes (Setopus) tongiorgii Balsamo, 1982 ; designation by Schwank (1990) </p>
            <p> According to Schwank (1990, p. 42) the genus  Dasydytes includes 3 subgenera: D. (  Dasydytes s.s. ), D. (  Setodytes ) and D. (  Setopus ). Schwank established the subgenus  Dasydytes (Setodytes) in order to distinguish  Dasydytes (S.) tongiorgii ,  D.(S.) chatticus and D.(s.)  lemnicola (nomen nudum) from the rest of the species in the subgenus D. (  Setopus ), because provided with spines with an accessory point. The former two species show also two peculiar caudal spines of different length and with an accessory point. However, both the spines with an accessory point and the unequal caudal spines are characters present in other species of  Dasydytidae , and do not appear to be diagnostic at subgeneric level. </p>
            <p> Thus, the subgenus  Dasydytes (Setodytes) is synonymized with the genus  Setopus (  syn . nov.), a taxon which has to be considered at a generic level, according to the original description by Grünspan (1908) and the emended diagnosis by Kisielewski (1991). The freshwater genus  Dasydytes counts now two subgenera (  Dasydytes sensu stricto ,  Prodasydytes ). </p>
            <p> Chaetonotida Paucitubulatina currently include 7 families (  Chaetonotidae ,  Dasydytidae ,  Dichaeturidae ,  Muselliferidae ,  Neogosseidae ,  Proichthydidae ,  Xenotrichulidae ) and 28 genera. Four families (  Dasydytidae ,  Dichaeturidae ,  Neogosseidae ,  Proichthydidae ), with 12 genera, are exclusively freshwater.  Chaetonotidae are composed of 12 genera, 5 of which are only freshwater (  Arenotus ,  Fluxiderma ,  Polymerurus, Romballichthys and  Undula ), 5 have both freshwater and marine species (  Aspidiophorus ,  Chaetonotus ,  Heterolepidoderma ,  Ichthydium ,  Lepidodermella ), and 2 are exclusively marine (  Caudichthydium ,  Halichaetonotus ).  Muselliferidae , with 2 genera (  Diuronotus ,  Musellifer ) and  Xenotrichulidae , with 3 genera (  Draculiciteria ,  Heteroxenotrichula ,  Xenotrichula ) comprise exclusively marine species. </p>
            <p> The complete list of the world freshwater species of Gastrotricha currently considered as reliable species, and indicated with the updated taxonomic name, is given in the Appendix, also including the only two species incertae sedis of  Macrodasyida which have been found in fresh waters. For completeness also the species inquirendae, the species incertae sedis and the nomina nuda are reported, and the updated numbers of the reliable species (both freshwater and marine) of each genus and subgenus is given. </p>
            <p>This checklist is a part of a complete dataset of freshwater species of Gastrotricha of the world, which includes taxonomical comments and geographical distribution at biogeographical region and/or at country/ State level of each species, as well as a list of the bibliographic references.
