Integrative Descriptions of Two New <i>Mesobiotus</i> Species (Tardigrada, Eutardigrada, Macrobiotidae) from Vietnam

To date, 34 tardigrade taxa have been recorded from Vietnam and this includes only two macrobiotid species belonging to the genus <i>Mesobiotus</i>. In this paper, two additional species of this genus, one of the <i>M. harmsworthi</i> group and one of the <i>M. furciger...

Sumario:To date, 34 tardigrade taxa have been recorded from Vietnam and this includes only two macrobiotid species belonging to the genus <i>Mesobiotus</i>. In this paper, two additional species of this genus, one of the <i>M. harmsworthi</i> group and one of the <i>M. furciger</i> group, are reported and described as new for science (<i>Mesobiotus imperialis</i> <b>sp. nov.</b>, <i>Mesobiotus marmoreus</i> <b>sp. nov.</b>). Both descriptions have an integrative character providing detailed morphological and morphometric data collected by phase contrast and scanning electron microscopy that are linked to genetic data. The latter constitute DNA sequences of molecular markers that are commonly used in tardigrade taxonomy. The genus phylogeny is also provided, elucidating the phylogenetic position of the newly discovered taxa.
