Phylogenetic position of two Macrobiotus species with a revisional note on Macrobiotus sottilei Pilato, Kiosya, Lisi & Sabella, 2012 (Tardigr…

In a moss and lichen sample collected on the Polish coast, a new population of Macrobiotus sottilei was found. Given that the original description of M. sottilei was based solely on the morphology observed under light microscopy and measurements of a few individuals, we provide, by means of integrative taxonomy, a revisional note on this species. We present a comprehensive set of morphometric and morphological data from light and scanning electron microscopy analysis together with nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments. We also provide the same set of DNA sequences for Macrobiotus glebkai from a population recently found i…
