“…Eight species names were originally classified in Paradoris : P. tsurugensis Baba, 1986, P. ceneris Ortea, 1995, P. inversa Ortea, 1995, P. leuca Miller, 1995, P. mollis Ortea, 1995, P. araneosa Valdés, 2001, P. imperfecta Valdés, 2001, P. lopezi Hermosillo & Valdés, 2004. None of these names has been re‐allocated to a different taxon, although Valdés (2001) argued that: ‘it is likely that P. leuca does not belong to the genus Paradoris .’ Four species names have been secondarily transferred to Paradoris : Percunas mulciber Marcus, 1970, transferred to Paradoris by Marcus (1976); D. indecora Bergh, 1881, transferred by Templado (1984), and regarded by Ortea (1995) as the valid name for P. granulata Bergh (1884); D. dubia Bergh, 1904 and D. liturata Bergh, 1905, transferred by Dayrat & Gosliner (2005). Note that the two names D. egena Bergh, 1904 and Alloiodoris nivosus Burn, 1958 must be counted as potentially valid species names of Paradoris because Burn (1969) regarded them as synonyms of D. dubia Bergh, 1904.…”

“…Finally, note that several authors mentioned or commented on indecora , granulata , and cavernae when describing new species of Discodoris or Paradoris , but without providing new data (e.g. Bergh, 1884; Marcus, 1965, 1976; Marcus & Marcus, 1967; Baba, 1989; Miller, 1995).…”

“…Finally, all the authors who have created new species names in, or transferred existing species to, Paradoris after 1965 (e.g. Marcus, 1976; Baba, 1986; Miller, 1995; Ortea, 1995; Valdés, 2001) have ignored the species name lora , despite the fact that Ernst Marcus had rightly pointed out that the shape of the radula was a close similarity between lora and indecora , a species transferred to Paradoris by Templado (1984).…”

Paradoris , traditionally a generic taxon of discodorid sea slugs, is revised for the first time. One hundred and thirty specimens were examined, including all types and most of the nontype specimens available. New records for Paradoris are provided: South Africa, Tanzania, Seychelles, Western Australia, Thailand, Philippines, shallow waters of New Caledonia, southern Japan, and Hawaii. The individual variation of all taxonomic characters is thoroughly evaluated. Prior to the present study, Paradoris included 15 nominal species: 12 valid names and three synonyms. Three additional names, Discodoris erythraeensis , D. lora , and D. cavernae , are re-allocated to Paradoris , based on phylogenetic analysis. A phylogenetic diagnosis is provided for Paradoris : in particular, two new synapomorphies are described. Eight species names are regarded as valid: P. araneosa , P. dubia , P. erythraeensis , P. indecora , P. liturata , P. lopezi , P. mulciber , and P. tsurugensis . However, most of these species are poorly known, i.e. from very few specimens, and their taxonomic status might change when more individuals are available. P. lora is regarded as a nomen dubium . Six new synonymies are proposed, and explained by the fact that: (1) species names were created for one or a few specimens, without considering individual variation; (2) authors have not worked within a phylogenetic framework and have created new species names without considering all the existing species names already available within Paradoris . Three new morphospecies are described, but not formally named because their taxonomic status is still uncertain for several reasons (e.g. lack of knowledge of individual variation for some critical features).

Eveline du Bois-Reymond Marcus ABSTRACTThe characters useful for determination are discussed and a key to the 8 Central and Eastern Atlantic recognizable species is given.Of the 18 species of Onchidella reported from the Atlantic, two, pachyderma (Plate, 1893) and pulchella Watson, 1925, are not recognizable. The same holds for celtica (Seurat, 1932). O. remanei Marcus, 1956, was found to be a junior synonym of celtica (Cuvier, 1817). The species of which material was now studied, celtica, incisa, marginata, maculata, accrensis and capensis, are described, as well as the probably new species, O. philippei. Onchidella indolens, floridana, brattstroemi, wah and miusha were treated in part 1. Some observations on O. floridana are added. On chidella is the only genus of the Onchidiacea occurring in the Atlantic.The distribution o f the species is shown on the map (Fig. 56). INTRODUCTIONAn ample material of Onchidella incisa collected by Joseph Rosewater at Ascen sion and some specimens that Hans Brattstrpm brought form the warm Western Atlan tic and entrusted to me, as well as some living Onchidella capensis given to me by Ro berta Griffiths during my visit to Cape Town in 1977, determined me to return to the pulmonate genus Onchidella. Philippe Bouchet, Hélène Gantés and Henry B. Coomans sent me some samples from West Africa. The British Museum (Nat. Hist.) entrusted me with specimens of O. marginata, O. maculata and O. accrensis. Many friends helped me with literature. My sincere thanks are due to all of them.The species treated in part I are not discussed again here, only the diagrams of their male organs are repeated for comparison ( Fig. 1 H-N).List of the Atlantic species of Onchidella 1. celtica (Cuviers, 1817) (Figs. 1A, 2-10). 2. incisa (Quoy & Gaimard, 1832) (Figs.

The Atlantic Species o f Onchidella (Gastropoda Pulmonata) 3 GENERAL REMARKSThe classification of this group was a troublesome task, as most of the older, even if long and detailed, descriptions are incomplete for specific distinction. Hoff mann (1928) in several cases synonymized two or three species without having material to compare them. The dissection of specimens from their original locality has proven that Hoffman was not always right. Therefore in the present paper I describe mainly those organs which I found usefu...
