“…More sampling in different regions and ecosystems is needed to evaluate the species richness and patterns of the species distribution properly. Noteworthy, it is not just about poor knowledge of tardigrades in Ukraine; similar situation was already reported for Poland (Kaczmarek et al, 2018), Belarus (Pilato et al, 2012), Romania (Ciobanu et al, 2014), Bulgaria (Yankova et al, 2016) and some other neighboring countries. The distribution ranges of many tardigrade species are not quite clear even in the regions where intense research had been performed in the past.…”

“…M. vladimiri described from Andalo, Italy (Bertolani et al, 2011a) was also reported from several other localities in Italy (Roszkowska et al, 2019), Germany (Bertolani et al, 2011b), and Poland (Nowak, Stec, 2017;Kaczmarek et al, 2018).…”

“…M. polonicus was earlier reported only from its type locality in Wielkopolska Province in Poland (Pilato et al, 2003) and Pomerania Province (Kaczmarek et al, 2018), also in Poland. M. sottilei described from Zhodino, Belarus (Pilato et al, 2012) was later reported from Pomerania Province, Poland (Kaczmarek et al, 2018) and also Trento and Olbia-Tempio Provinces, Italy (Roszkowska, 2019).…”

New records of tardigrade species of the Macrobiotus hufelandi group (Tardigrada: Eutardigrada: Macrobiotidae) from Ukraine

Species of the Macrobiotus hufelandi group are among the most well known and commonly found tardigrades. They are reported in almost every study of Tardigrada diversity in terrestrial habitats. In spite of this, zoogeographical data on this group remain ambiguous and insufficient. Since most species of the M. hufelandi group have been described in the last three decades, many older records need to be confirmed or revised. In this study we aimed to investigate, which species may be present in Ukraine, since most Ukrainian records of this group are outdated. We studied samples of mosses and lichens collected from different regions of Ukraine (mainly in the East and South of the country) in 2007–2019. Tardigrades were extracted from samples and mounted on permanent slides in Faure's medium. After primary identification of genera and species groups we focused on 13 samples containing local populations of the M. hufelandi group. Details of animal and egg morphology were studied under high magnifications of phase contrast light microscopy. Species were identified based on morphology of the oral cavity armature, egg shell morphology, animal cuticle granulation, as well as some morphometric characters of claws and bucco-pharyngeal apparatus. This research revealed the presence of at least six different species in Ukraine: M. glebkai Biserov, 1990; M. hufelandi C.A.S. Schultze, 1834; M. macrocalix Bertolani & Rebecchi, 1993; M. polonicus Pilato, Kaczmarek, Michalczyk & Lisi, 2003; M. sottilei Pilato, Kiosya, Lisi & Sabella, 2012; M. vladimiri Bertolani, Biserov, Rebecchi & Cesari, 2011. Three of them: M. macrocalix, M. sottilei, and M. vladimiri are reported in this study from Ukraine for the first time. Adding three more species recorded in earlier studies: M. diversus Biserov, 1990; M. persimilis Binda & Pilato, 1972, and M. sapiens Binda & Pilato, 1984 – gives the total count of at least 9 species of the group in Ukraine. However, according to the recent studies on species complexes the real species diversity is very likely to be higher. Nevertheless, more sampling and obtaining molecular data from different Ukrainian populations of the M. hufelandi group from Ukraine are required.

“…These microinvertebrates have a global distribution and inhabit a large variety of habitats from the greatest depths of the ocean to the highest mountain peaks, as well as extreme environments such as cryoconite holes (Nelson et al, 2015;Zawierucha et al, 2015). Research on the tardigrade fauna in Poland has been conducted for more than a century (Minkiewicz, 1914;Jakubski, 1915) and up to now 110 species have been reported from this country (Dastych, 1988;Gąsiorek et al, 2016;Nowak and Stec, 2017;Stec et al, 2017b;Kaczmarek et al, 2018; and literature cited therein).…”

An integrative description of Macrobiotus hannae sp. nov. (Tardigrada: Eutardigrada: Macrobiotidae: hufelandi group) from Poland

A new species of the Macrobiotus hufelandi group is described from Poland. An integrative taxonomic approach was applied by combining morphological and morphometric analysis imaging under phase contrast and scanning electron microscopy with molecular analysis (four molecular markers) to unambiguously support the establishment of the new species. The specimens of Macrobiotus hannae sp. nov. are similar to three taxa of the Macrobiotus hufelandi complex:

“…It differs from M. sottilei, known from its type locality in Belarus (Pilato et al 2012) but also from Poland (Kaczmarek et al 2018) and Italy (Roszkowska et al 2019), by the presence of three distinct teeth/ridges in the dorsal portion of the third band of teeth (the teeth/ridges of the dorsal portion fused and form a continuous arc in M. sottilei) and by a slightly more posterior stylet support insertion point (pt = 76.7-81.6 in the new species vs 75. 3-76.6 in M. sottilei).…”

In this paper we describe two new tardigrade species belonging to the Macrobiotus hufelandi complex: Macrobiotus noongaris sp. nov. from Perth, Australia, and Macrobiotus kamilae sp. nov. from Mussoorie, India. Live specimens extracted from moss samples were used to establish laboratory cultures in order to obtain additional animals and eggs needed for their integrative descriptions. These descriptions are based on traditional morphological and morphometric data collected using both light and scanning electron microscopy, which, at the same time, were associated with DNA sequences of four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI). The use of DNA sequences allowed for a more accurate verification of the taxonomic status of M. noongaris sp. nov. and M. kamilae sp. nov as independent species of the hufelandi group. Although they both exhibit typical inverted goblet-shaped processes, they represent a recently discovered clade, which was thought to group species with modified morphology of egg processes. Thus, this contribution expands the definition of the mentioned clade and constitutes another link that will be helpful for future studies on the evolution of the M. hufelandi complex.
