“…Pseudoceros bicolor on the other hand, was absent from sea-grass beds. This contrasts with Rawlinson (2008) who lists P. bicolor as the second most common cotylean found in all habitat types. The reason for the discrepancy is that she did not separate the different colour morphs but instead lumped them all into one large, general "bicolor" assemblage, which resulted in a large overestimate for P. bicolor and a gross underestimate of P. rawlinsonae (Rawlinson 2008).…”

Although in this study we confirm the importance of colour pattern (but not colouration) for species distinctions in Pseudocerotidae, we strongly caution against its sole use and emphasize the necessity of adding morphological and molecular data for accurate species identifications.…”

The polyclad Pseudoceros bicolor derives its name from a distinctive two-coloured dorsal colouration, which consists of a very dark, almost black central area with acute black lobes extending towards a translucent greyish margin. At least three different colour morphs have been described, ranging from a pale speckled brown through an evenly dark brown form, to a morphotype resembling the original species description. Pseudoceros aureolineatus is easily confused with the light brown colour morph of P. bicolor, and P. rawlinsonae resembles both P. bicolor and P. aureolineatus. Using morphological characters of newly collected specimens and nucleotide sequences of the 28S ribosomal DNA gene, the taxonomic validity of P. rawlinsonae and P. bicolor is confirmed and the descriptions of their colouration are emended. The new subspecies, P. bicolor marcusorum subsp. nov. is erected, the genus Cryptoceros is eliminated, and the new combination Maritigrella aureolineata comb. nov. (Euryleptidae) is established for P. aureolineatus.

“…It is known that, in general, polyclads have cryptic behavior, living under rocks and often associated with invertebrates on which they feed (Marcus & Marcus 1951;Newman et al 2000;Newman & Cannon 2003). They are also important predators in hard bottom environments (Rawlinson 2008;Rawlinson et al 2011) and are used in studies involving regeneration (Egger et al 2007), toxicology andpredation (Ritson-Williams et al 2006), literature (Pearse & Wharton 1938;O´Connor & Newman 2001;Pérez-Portela & Turon 2007) and confirm the predominance of carnivory in the group (Hurley 1975;Galleni et al 1980;Perrone 1987), despite the existence of symbiont species (Smith 1960;Doignon et al 2003;Faubel et al 2007). Ascidians are frequent Cotylean preys, despite their known defence compounds (Pisut & Pawlik 2002).…”

Polyclads are free-living Platyhelminthes with a simple, dorsoventrally flattened body and a much ramified intestine. In Brazil, 66 species are reported; only three from Rio de Janeiro State (RJ). The main objective of this study is to describe and illustrate coloration pattern, external morphology, reproductive system morphology and, when possible, biological and ecological aspects of species of the suborder Cotylea found in Cabo Frio, RJ. Of the 13 cotylean polyclad species found, Pseudobiceros pardalis, Cycloporus variegatus and Eurylepta aurantiaca are new records from the Brazilian coast and one species is new to science, Pseudoceros juani sp. nov. Feeding observations were made of four species. It is the first time that Lurymare utarum, Cycloporus gabriellae, C. variegatus and E. aurantiaca are illustrated with digital photographs of live specimens and histological preparations. This study increases to 70 the number of Brazilian Polycladida and to 14 the number of species known from Rio de Janeiro State. However, the knowledge about Polycladida in Brazil still has gaps, with great parts of the coast remaining unsampled.

“…It is also known from Curaçao (Marcus & Marcus, 1968). This species is considered by Rawlinson (2008) as representative of seagrass habitat. We found our specimens both in sandstone and coral reefs and E. evelinae was the most common species in our samplings.…”

First records of the order Polycladida (Platyhelminthes, Rhabditophora) from reef ecosystems of Alagoas State, north-eastern Brazil, with the description ofThysanozoon alagoensissp. nov.

The 230 km long coast of Alagoas State, in north-eastern Brazil, has diverse reef ecosystems, made from corals and of sandstone, that harbour a wide range of marine invertebrate fauna. Little is known about turbellarians of the order Polycladida in most parts of the Brazilian coast, with no record from Alagoas up to date. To fill this gap expeditions were conducted on the reefs from the central coast of Alagoas, where 11 Polycladida species were found:Pericelis cata, Enchiridium evelinae, Pseudoceros bicolorand a possible new colour variation of this species,Pseudoceros rawlinsonae, Pseudobiceros pardalis, Thysanozoon brocchii, Thysanozoon alagoensissp. nov.,Armatoplana leptalea, Adenoplana evelinae, Latocestus brasiliensis, Phaenocelis medvedica. The species are described in detail through photos of live specimens and histological sections. The present work adds six species to the north-eastern Brazilian coast, one of them a new species, and all 11 species are for the first time reported from Alagoas State. Also, it is the first time thatPhaenocelis medvedica, Adenoplana evelinae, Latocestus brasiliensisandArmatoplana leptaleaare illustrated by full colour photos of live specimens and histological sections.
