Acanthodasys caribbeanensis sp. n., a new species of Thaumastodermatidae (Gastrotricha, Macrodasyida) from Belize and Panama. [PDF]
Zookeys, 2010 We describe one new species of Acanthodasys (Gastrotricha, Macrodasyida, Thaumastodermatidae) collected from sublittoral sites around Carrie Bow Cay, Belize and Isla Colón in the Bocas del Toro archipelago, Panama. Though eight species of Acanthodasys are currently recognized, no species has yet been reported from the Caribbean.

Integrated data analysis allows the establishment of a new, cosmopolitan genus of marine Macrodasyida (Gastrotricha). [PDF]
Sci Rep, 2019 AbstractMacrodasyida (phylum Gastrotricha) comprises 365 species distributed across 34 genera and 10 families. However, current classification is under revision due to the contradictory results of molecular and morphological cladistic analyses. Studies aimed at bridging the gaps took advantage of supplementary assessments of poorly known species and ...

A New Species of Paraturbanella Remane, 1927 (Gastrotricha, Macrodasyida) from the Brazilian Coast, and the Molecular Phylogeny of Turbanellidae Remane, 1926 [PDF]
Diversity, 2020 The family Turbanellidae includes Paraturbanella and five other genera. Despite the fact that the monophyly of these genera were not satisfactorily tested, species belonging to the genus Paraturbanella are distinguished from turbanellids by sharing a ...

Marine Gastrotricha of the Near East: 1. Fourteen new species of Macrodasyida and a redescription of Dactylopodola agadasys Hochberg, 2003. [PDF]
Zookeys, 2011 The near eastern geographical region is almost devoid of reports of macrodasyidan gastrotrichs, the exceptions themselves being part of this study. Here, as Part 1 are described fourteen new Macrodasyida from countries of the Near East (Cyprus, Egypt and

Dendrodasys duplus, a New Gastrotrich Species (Macrodasyida: Dactylopodolidae) from South Korea
Animal Systematics, Evolution and Diversity, 2014 A new gastrotrich species of the genus Dendrodasys (Dactylopodolidae) is described on the basis of specimens collected from sublittoral fine sandy bottoms at Uljin, East Sea and at Gujwa, the northeastern coast of Jeju Island, South Korea. Dendrodasys duplus is characterized by a triangular head with lateral lobes extending outward, two pairs of pestle

Reproductive system and spermatozoa ultrastructure support the phylogenetic proximity of Megadasys and Crasiella (Gastrotricha, Macrodasyida) [PDF]
Contributions to Zoology, 2014 The reproductive system and the spermatozoon of Megadasys sterreri from Lanzarote (Canary Islands, Spain) were studied at structural and ultrastructural levels. The species is a simultaneous hermaphrodite with cross-fertilization and shows paired gonads,

Description of a New Scaled Species of Ptychostomella (Gastrotricha: Macrodasyida) from the Brazilian Coast and a Cladistics Analysis of the Genus [PDF]
Taxonomy, 2021 A new species of marine Gastrotricha from the north coast of São Paulo state, Brazil, is described. Adults of Ptychostomella sebastiana sp. nov. are unique in that they possess a pair of dorsolateral “rod-like” cephalic sensory organs and subrectangular ...

Phylogeny of Thaumastodermatidae (Gastrotricha: Macrodasyida) inferred from nuclear and mitochondrial sequence data. [PDF]
PLoS One, 2011 BackgroundPhylogenetic relationships within Gastrotricha are poorly known. Attempts to shed light on this subject using morphological traits have led to hypotheses lacking satisfactory statistical support; it seemed therefore that a different approach ...

Macrodasyida (Gastrotricha): a cladistic analysis of morphology [PDF]
Invertebrate Biology, 2001 Abstract. A cladistic analysis based on 33 morphological characters was performed for the 31 genera currently assigned to the order Macrodasyida (Gastrotricha). Outgroup analysis indicated that the order is monophyletic and that it is defined by the structure of the pharynx and the complex distribution of duo‐gland adhesive organs.
