“…Like P. hymanae, the cerebral eye cluster of P. cata forms an elongated oval cluster (e.g. Marcus & Marcus 1968, Bahia & Padula 2009, Queiroz et al 2013) different, therefore, from P. tectivorum sp. nov. (Fig.…”

We describe a new marine snail-eating flatworm, Pericelis tectivorum sp. nov., found in coral-bearing marine aquaria. Pericelis tectivorum sp. nov. is characterised by several differential characters of the external and internal morphology like 1) a long line of frontal eyes extending anteriorly; 2) the length of the penis papilla; 3) the spherical seminal vesicle; 4) the lack of the enlargements of the ejaculatory duct; 5) the uterine vesicles, which start posterior of the female genital at the level of the sucker and 6) the distinct sucker. The combination of these characters in one species is unique and therefore the studied specimens are recognised by us as a new species. We additionally present a phylogenetic reconstruction using partial 28S rDNA sequences including three congeners. Our analysis demonstrates that P. tectivorum sp. nov. differs also genetically from other Pericelis species included in this analysis.

“…This species was recorded from Curaçao (type locality; Marcus & Marcus, 1968), Colombian Caribbean (Quiroga et al , 2004b), Cabo Frio, south-eastern Brazil (Bahia & Padula, 2009) and Salvador, north-eastern Brazil (Queiroz et al , 2013). This is the first record of this species from Alagoas State.…”

“…The specimen herein studied was smaller than those found at Cabo Frio, south-eastern Brazil (Bahia & Padula, 2009) and those from Bahia State, north-eastern Brazil (Queiroz et al, 2013). During the collections two specimens of P. cata were placed in the same container as some specimens of the opisthobranch mollusc Micromelo undatus.…”

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.

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.
