“…Minibiotus jonesorum was described from Michigan (Meyer et al 2011) and has since has been reported from British Columbia (Meyer and Hinton 2012) and Georgia (Hinton and Meyer 2009). This record adds to the biodiversity list for the state and expands the home range of the species (Lehmann, Shivley, and Miller 2007).…”

Two male red-eared slider turtles (Trachemys scripta elegans) were captured by the BioScience class of the Blue Valley Center for Advanced Professional Studies (CAPS) during routine study. The animals were brought in for measurements and teaching before being released. The class asked if there might be tardigrades in the algae on their backs. Scrapings were examined and two active Minibiotus jonesorum tardigrades were found on one of the turtles. Rotifers, nematodes, and ciliates were also observed. This is the first record of tardigrades being found on the back of a turtle and suggests another vector for the movement and dispersal for these non-self-dispersing microscopic animals. This record documents an extension of the range for the species of tardigrade, reports the first incident of this terrestrial species in an aquatic habitat, and adds to the diversity of the state of Kansas.

Both species have posterior bands of gibbosities, cuticles with numerous small pores, and eggs with punctate shells and long, thin processes (Pilato et al 1989 REMARKS.-Tardigrades with narrow buccal tubes, including species in the genus Minibiotus, are known to feed on plant material (Lehmann et al 2007).

“…Terrestrial species occur in mosses, lichens, liverworts, and leaf litter, and are renowned for their ability to enter a cryptobiotic state (anhydrobiosis) in response to desiccation. Terrestrial tardigrades include both herbivorous and carnivorous species that feed on nematodes, rotifers, and other tardigrades (Lehmann et al 2007). Over 200 species of freshwater and terrestrial tardigrade are known to occur in North America .…”

The genus Barbaria, recently established to accommodate the former Echiniscus bigranulatus group, is a tardigrade group emblematic for the South American tardigrade fauna. This unappendaged echiniscid lineage is widely recognized for the so-called ‘double’ sculpturing composed of endocuticular pillars and pseudopores or pores in the dorsal cuticle. The phylogenetic relationships in the genus have so far been completely unknown, but the discovery of two new species (B. paucigranulata sp. nov. and B. weglarskae sp. nov.), together with new genetic data for further six species (B. bigranulata, B. charrua comb. nov., B. danieli, B. jenningsi, B. madonnae and B. ollantaytamboensis), create an opportunity not only to uncover phyletic relationships, but also to reconstruct morphological evolution in the genus. To achieve this, we sequenced five genetic markers (18S rRNA, 28S rRNA, ITS1, ITS2, COI) for multiple populations of eight species of Barbaria (two-thirds of all known species) collected in Alabama (USA), Argentina and the Antarctic, and we analysed them in tandem with detailed morphological data. Our phylogentic analysis and the reconstruction of evolution of morphological traits suggests that the ancestor of the genus inhabited the Neotropics, and it was morphologically most similar to B. bigranulata. We also analyse literature records of Barbaria and conclude that the genus is most likely limited to the Neotropics, Antarctica and southern parts of the Nearctic. The findings are discussed in the context of the phylogeny of the Echiniscus evolutionary line.
