Hypsibius vaskelae, a new species of Tardigrada (Eutardigrada, Hypsibiidae) from Russia

Hypsibius vaskelae sp. nov. (Tardigrada, Eutardigrada, Hypsibiidae) is described from a freshwater sample collected in the vicinity of Saint-Petersburg. The new species has wrinkled cuticle, bucco-pharyngeal apparatus with two elongate macroplacoids and septulum, and cuticular bars between the bases of inner and outer claw and near the base of the inner claw on legs I–IV. Hypsibius vaskelae sp. nov. is most similar to Hypsibius marcelli Pilato, 1990 and H. septulatus Pilato, Binda, Napolitano & Moncada, 2004, but differs from both in having wrinkled dorsal cuticle, thinner claws, and presence of lunules on the claws of all legs.

A New Species

The revision of specimens in the lichen herbarium of the University of Tartu revealed 127 specimens representing 86 species from the Leningrad Region and Saint Petersburg; these include Calicium adspersum published as a new species for the Leningrad Region and Carbonicola anthracophila reported for the first time for the Eastern Leningrad Region. A curious finding is Umbilicaria muehlenbergii, collected in 1954 in the northern part of Karelian Isthmus. Forgotten collections by Anne-Liis Sõmermaa (1972) from the territory of the modern Vepssky Forest Nature Park, by Haide-Ene Rebassoo (1988) from Maly Tuters Island (Vähä-Tytärsaari, Säyvö) and by Paul von Kühlewein (“regio Petropolitano”, 19th century) are of special interest.

A New Species

A new tardigrade, Minibiotus xavieri sp. nov., is described from lichen and moss samples collected in Parque Biologico de Gaia, Avintes, Portugal. The new species has variously shaped pores forming transverse bands around the cuticle; granulation on legs absent. Peribuccal lamellae absent, peribuccal papulae present as in all species of Minibiotus. Buccal tube narrow with an anterior bend; pharyngeal bulb with apophyses, three small macroplacoids and microplacoid. Minibiotus xavieri sp. nov. differs from the species of the genus with a similar cuticular ornamentation (with pores of variable shape forming transverse bands) (M. eichorni Michalczyk & Kaczmarek, 2004, M. orthofasciatus Fontoura, Pilato, Lisi & Morais, 2009, M. vinciguerrae Binda & Pilato, 1992, M. furcatus (Ehrenberg, 1859)) in some qualitative or quantitative characters of the bucco-pharyngeal apparatus, and/or claws and of the eggs. The new species is also similar to two species today ascribed to the genus Macrobiotus but whose systematic position needs to be better analyzed, Macrobiotus lazzaroi Maucci 1986 and Macrobiotus pseudofurcatus Pilato, 1972. Minibiotus xavieri sp. nov. differs from them in some characters of the animal (narrower buccal tube, some characters of the claws) and of the eggs.

A New Species

A new species is described for which a new genus, Bindius gen. nov., is also instituted. This new genus belongs to the family Hypsibiidae. The claws are of the Hypsibius type; the bucco-pharyngeal apparatus is of the Diphascon model (i.e., with an anterior rigid buccal tube and a posterior, flexible pharyngeal tube), and it is a variant of the Diphascon type; it is characterized by large apophyses for the insertion of the stylet muscles, asymmetrical with respect to the frontal plane for shape and dimensions; the dorsal apophysis is triangular in shape with rectilinear dorsal margin and posterior apex very distant from the buccal tube wall; the ventral apophysis is similar to the one of Diphascon, i.e., in the shape of a semilunar hook, but larger. The new species, Bindius triquetrus sp. nov., has smooth cuticle; eye spots absent; elongated pharyngeal bulb with small apophyses and three long, rod-shaped macroplacoids; a small, very faint, microplacoid may be present; septulum absent; claws slender; lunules and other cuticular thickenings on the legs absent.
