An Integrated Morphological and Molecular Approach to the Description and Systematisation of a Novel Genus and Species of Macrodasyida (Gastrotricha). [PDF]
PLoS ONE, 2015 Gastrotricha systematics is in a state of flux mainly due to the conflicts between cladistic studies base on molecular markers and the classical systematisation based on morphological traits.

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

Integrative taxonomy of a new Redudasys species (Gastrotricha: Macrodasyida) sheds light on the invasion of fresh water habitats by macrodasyids. [PDF]
Sci Rep, 2019 The order Macrodasyida (Gastrotricha) includes over 350 marine species, and only 3 freshwater species (Marinellina flagellata, Redudasys fornerise, R. neotemperatus). Herein we describe a new freshwater species of Macrodasyida, Redudasys brasiliensis sp.

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 ...

Reproductive organs and spermatogenesis of the peculiar spermatozoa of the genusKryptodasys(Gastrotricha, Macrodasyida), with an appraisal of the occurrence and origin of the tail‐less spermatozoa in Gastrotricha [PDF]
Journal of Zoological Systematics and Evolutionary Research, Volume 59, Issue 8, Page 1673-1688, November 2021., 2021 The presence of aflagellate spermatozoa in two species of Kryptodasys (Fam. Macrodasyidae), a gastrotrich genus recently described, is reported. Their ultras-tructure shows common features, which appear peculiar to the genus and different from those of ...

New Data on Reproductive System and Spermatozoa Confirm Macrodasys as a Model in Comparative Reproductive Analysis in Macrodasyida (Gastrotricha) [PDF]
Water, 2022 Gastrotricha Macrodasyida, aquatic worms, are primarily hermaphrodites with internal cross-fertilization and indirect sperm transfer. Insightful information on this matter dates to 1978 and derives from an illuminating work focused on two Macrodasys ...

Integrated data analysis allows the establishment of a new, cosmopolitan genus of marine Macrodasyida (Gastrotricha). [PDF]
Sci Rep, 2019 Macrodasyida (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.
