Diphascon (Diphascon) faialense sp. nov. a new species of Tardigrada (Eutardigrada, Hypsibiidae) from the Azores and a key to the species of the D. pingue group

A new tardigrade, Diphascon (Diphascon) faialense sp. nov., is described from a moss sample collected on Faial Island, the Azores. This species belongs to the Diphascon pingue group. It differs from all other species of the group mainly by quantitative characteristics of the bucco-pharyngeal apparatus and of the claws.

A New Species

A new species, Macrobiotus derkai sp. nov., is described from a moss sample collected in the alpine zone of Sierra Nevada del Cocuy Mts (NE Colombia). It differs from the most similar species, Macrobiotus huziori Michalczyk & Kaczmarek, 2006 mainly in the location of the second macroplacoid and in the dimensions of accessory points on the claws. Eggs of the new species have the same type of areolation as eggs of M. huziori but they differ from the latter in the size and number of processes. The differences between the new species and others having similar number and shape of placoids are discussed. An identification key for these species is also provided. A round depression on the dorsal head cuticle is reported in Tardigrada for the first time. The results of a morphometric analysis of the new species are also given.

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 heterotardigrade, Bryodelphax aaseae sp. nov. is described from a small moss sample collected in the Rano Kau Crater on Easter Island (Rapa Nui) in 1989. The new species belongs to the group of species within the genus that have ventral plates. B. aaseae sp. nov. is similar to B. weglarskae (Pilato, 1972), B. sinensis (Pilato, 1974) and B. iohannis Bertolani, Guidi & Rebecchi, 1995 but differs from them mainly by a different number and arrangement of ventral plates. This is the first record of the genus Bryodelphax from Easter Island/Rapa Nui.

A New Species

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 heterotardigrade, Echiniscus barbarae sp. nov., is described from a moss sample collected in Cuba. This species belongs to the ‘arctomys group’, which contains many problematic species. The new species differs from the most similar species Echiniscus limai mainly by having cephalic, scapular and terminal dorsal plates not faceted. This paper is the first record of Tardigrada from Cuba.

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.

A new heterotardigrade, Bryodelphax brevidentatus sp. nov. is described from moss sample collected in China. The new species is most similar to Bryodelphax tatrensis (W¨¬glarska) but differs from it mainly by the different appearance of the dentate collar (different in shape and length of teeth), shorter cirri A and shorter claws.
