Architecture of the nervous system in two Dactylopodola species (Gastrotricha, Macrodasyida)
Zoomorphology, 2008Immunohistochemical stainings have become standard tools to describe the nervous system, but usually only singular or few markers are used and consequently show only subsets of neurons within the nervous system. We investigated two species of Dactylopodola (Gastrotricha, Macrodasyida) with a broad set and combination of markers, to represent the ...

Two new species ofUrodasys(Gastrotricha, Macrodasyidae) with cuticular stylet
Italian Journal of Zoology, 1998Abstract Most species of Urodasys bear a clearly structured cuticular stylet in the caudal organ, that constitutes a powerful diagnostic feature. On the basis of the morphology of this stylet, two new species, Urodasys acanthostylis and U. uncinostylis, are described. Urodasys acanthostylis is diagnosed by a stylet with the tubular portion clearly bent

Two new species ofThaumastoderma(Gastrotricha, Macrodasyida) from Korea
Sarsia, 1998Abstract Two new marine gastrotrichs of the genus Thaumastoderma are described from South Korea T. coronarium sp. nov. was collected from the intertidal zones of Manripo beach and Sopori, Tokchok Island in the Yellow Sea. This species seems to be most closely related to T. bifurcatum CLAUSEN, 1991 or T.

Adults of Dinodasys mirabilis were studied for the first time. The specimens, collected from the west coast of Sweden, were investigated alive and with electron microscopy. Sexually mature specimens attain a total length of 450–490 μm; the adhesive apparatus is made up of anterior, lateral, ventrolateral, dorsal and posterior tubes; and one pair of ...

Spermatogenesis and sperm ultrastructure of the macrodasyidan gastrotrich Cephalodasys maximus are described by means of transmission electron microscopy. The filiform sperm consists of an acrosomal accessory structure and an acrosomal vesicle, both being surrounded by spiralled material.

Ultrastructure of the sensory palps ofTetranchyroderma papii (Gastrotricha, Macrodasyida)
Zoomorphologie, 1980The sensory palps of the macrodasyoid gastrotrichTetranchyroderma papii contain processes from two types of cell: 22–23 bipolar primary sensory cells and two to three support cells. In the proximal region of the palp each sensory cell contains a short ciliary segment with a basal body and from this ciliary segment a longer distal segment lacking ...

A new gastrotrich species of the genusTetranchyroderma(Macrodasyida: Thaumastodermatidae) from Korea
Proceedings of the Biological Society of Washington, 2014Abstract A new gastrotrich species of the genus Tetranchyroderma, bearing three-pronged cuticular hooks, was discovered in the Pacific, from littoral sandy bottoms of a beach at Joyagdo Island off Wando, south coast of the Korean Peninsula. Tetranchyroderma pinnatum, sp.

Abstract. The spermatozoa of two species of Macrodasyida (Gastrotricha), Urodasys anorektoxys and U. acanthostylis, show an ultrastructural organization diverging from one another and from other gastrotrichs: their main peculiarity is in the absence of mitochondria. In U.

Two new interesting species of Macrodasyida (Gastrotricha) from KwaZulu-Natal (South Africa)
Proceedings of the Biological Society of Washington, 2017Abstract This study is part of a larger research program aimed at shedding light on meiofauna and macrofauna communities of the subtropical Eastern Province of KwaZulu-Natal, South Africa. Previous articles on the phylum Gastrotricha have detailed faunistic and preliminary taxonomic data on marine and freshwater species found in the iSimangaliso ...

Macrodasyida are worm-like, hermaphroditic and marine gastrotrichs with about 350 species. Among all known Macrodasyida only Marinellina agellata, Redudasys fornerise and Redudasys sp. (Kanneby & Wicksten, 2014), were found in fresh waters respectively from an Austrian stream, a Brazilian articial reservoir and a USA aquifer.
