Cotylea (Polycladida): a cladistic analysis of morphology [PDF]

Invertebrate Biology, 2008
Abstract. Polyclad flatworms are acoelomate bilaterians found in benthic communities worldwide, predominantly in marine environments. Current polyclad systematics is unstable, with two non‐concordant classification schemes resulting in a poor understanding of within‐group relationships. Here we present the first phylogenetic framework for the suborder

Description of Pericelis flavomarginata sp. nov. (Polycladida: Cotylea) and its predatory behavior on a scaleworm

Zootaxa, 2020
We describe a new species of polyclad flatworm, Pericelis flavomarginata sp. nov., from the intertidal and subtidal zones along localities on the Pacific coast of Japan. Pericelis flavomarginata sp. nov. is characterized by i) the dorsal surface of the body fringed by a lemon-yellow line except for the tip of tentacles, with a narrow brown midline ...

A new bathyal species of Cestoplana (Polycladida: Cotylea) from the West Pacific Ocean

Marine Biodiversity, 2018
We describe Cestoplana nopperabo sp. nov. from 292- to 439-m depths in Sagami Bay, Japan. This is the eighth member of the genus, representing the first report of a bathyal polyclad from the Indo-West Pacific. Cestoplana nopperabo sp. nov. is characterized by lacking eyespots; it shows no color pattern on the dorsal surface of the body, unlike other ...

Ultrastructure of the ovary and oogenesis in the flatworm Prosthiostomum siphunculus (Polycladida, Cotylea)

Cell Biology International, 2016
AbstractBased on light and electron microscopy observations, oogenesis in the cotylean polyclad Prosthiostomum siphunculus was investigated for the first time. The numerous ovarian follicles are dispersed essentially in the dorsal parenchyma. In the follicles, a ventral germinative zone with undifferentiated germs cells of different sizes and a dorsal ...

Five new species of cotylean flatworms (Platyhelminthes: Polycladida: Cotylea) from Oaxaca, southern Mexican Pacific

Zootaxa, 2020
The flatworms of the suborder Cotylea live in diverse marine substrates such as rocks, seaweed and sand or in association with corals. In the Mexican Pacific, particularly on the coast of Oaxaca, knowledge about cotyleans is scarce, with only one record of the genus Pseudoceros.

First records of Pseudocerotidae (Platyhelminthes: Polycladida: Cotylea) from Patagonia, Argentina

Zootaxa, 2009
In this work we record two species belonging to the polyclad family Pseudocerotidae from the littoral zone of the Península Valdés (Patagonia, Argentina). This is the first record of members of Cotylea and the third of Polycladida from Argentina. The two new records are Phrikoceros mopsus, a species described for Brazil and Colombia and Thysanozoon ...
