Description of a new species of Paraplehnia (Polycladida, Stylochoidea) from Japan, with inference on the phylogenetic position of Plehniidae [PDF]

open access: yesZooKeys, 2019
We describe a new species of polyclad flatworm, Paraplehnia seisuiae sp. nov., from 298–310 m depths in the Sea of Kumano, West Pacific, Japan. Paraplehnia seisuiae sp. nov.

A molecular framework for the taxonomy and systematics of Japanese marine turbellarian flatworms (Platyhelminthes, Polycladida)

open access: yesAquatic Biology, 2017
The order Polycladida comprises a highly diverse and cosmopolitan group of marine turbellarian flatworms. Owing to the great morphological diversity and the absence of a molecular phylogeny, the classification of this group has always been controversial.

Morphology and phylogeny of two acotylean flatworms (Platyhelminthes, Polycladida) from the genera Cryptophallus and Limnoplana in the South China Sea [PDF]

open access: yesZooKeys
We describe two new species of the genera Cryptophallus Bock, 1913 and Limnoplana Faubel, 1983, which have not been reported for nearly a century. Herein, the genus Limnoplana represents a rare group of polyclads inhabiting brackish waters. Cryptophallus

Developmental diversity in free-living flatworms [PDF]

open access: yesEvoDevo, 2012
Flatworm embryology has attracted attention since the early beginnings of comparative evolutionary biology. Considered for a long time the most basal bilaterians, the Platyhelminthes (excluding Acoelomorpha) are now robustly placed within the Spiralia ...

Reinvestigating the early embryogenesis in the flatworm Maritigrella crozieri highlights the unique spiral cleavage program found in polyclad flatworms [PDF]

open access: yesEvoDevo, 2019
Background Spiral cleavage is a conserved, early developmental mode found in several phyla of Lophotrochozoans resulting in highly diverse adult body plans.

Does the frontal sensory organ in adults of the hoplonemertean Quasitetrastemma stimpsoni originate from the larval apical organ? [PDF]

open access: yesFrontiers in Zoology, 2020
Background The apical organ is the most prominent neural structure in spiralian larvae. Although it has been thoroughly investigated in larvae of the class Pilidiophora in phylum Nemertea, studies on its structure in other nemertean larvae are limited ...

Regeneration of the flatworm Prosthiostomum siphunculus (Polycladida, Platyhelminthes). [PDF]

open access: yesCell Tissue Res, 2021
AbstractFueled by the discovery of head regeneration in triclads (planarians) two and a half centuries ago, flatworms have been the focus of regeneration research. But not all flatworms can regenerate equally well and to obtain a better picture of the characteristics and evolution of regeneration in flatworms other than planarians, the regeneration ...
