In this paper, two species of cotylean Platyhelminthes are recorded for the first time from Qeshm Island, Persian Gulf, Iran. Pictures are taken from living specimens to illustrate shape and colour, and stained sections and drawings are used to describe ...

Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia
The systematics and distribution of the order Polycladida within the Macaronesian archipelagos are analysed. New species (Marcusia alba sp. nov., Prostheceraeus crisostomum sp. nov., Parviplana sodade sp. nov., Euplana claridade sp. nov., Stylochus salis

Ultrastructure of spermatogenesis and mature spermatozoa in the flatworm Prosthiostomum siphunculus (Polycladida, Cotylea) [PDF]
AbstractThis is the first study investigating spermatogenesis and spermatozoan ultrastructure in the polyclad flatworm Prosthiostomum siphunculus. The testes are numerous and scattered as follicles ventrally between the digestive ramifications. Each follicle contains the different stages of sperm differentiation.

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.

The ultrastructure of the apical organ of Curini‐Galletti's larva, a new polyclad larval type
Abstract Polycladida are the only free‐living flatworms with a planktonic larval stage in some species. Currently, it is not clear if a larval stage is ancestral in polyclads, and which type of larva that would be. Known polyclad larvae are Müller's larva, Kato's larva and Goette's larva, differing by body shape and the number of lobes and eyes.

The Order Polycladida comprises a diverse yet understudied group of free-living flatworms, traditionally divided into Cotylea and Acotylea based on the presence or absence of a ventral adhesive organ known as a cotyl. Species identification, particularly

The aim of this work is to provide some important morphological, ecological and reproductive features of 8 polyclad species from Tunisian waters belonging to Acotylea: Echinoplana celerrima Haswell, 1907, Leptoplana mediterranea (Bock, 1913), Discocelis tigrina (Blanchard, 1847) and Imogine mediterranea (Galleni, 1976) and Cotylea: Thysanozoon brocchii
