“…They were caused by the subchela of the male pereopod II while clasping the female during copulation. These marks are frequently found in females of Serolis species, as discussed by Moreira (1973 Etymology. -The name is derived from the Latin word "arcuatus" = arched, alluding to the animal's body convexity.…”

Available data are scanty on the deep-sea Isopoda fauna from the western South Atlantic Ocean, off southern Brazil (Menzies, 1962). In order to improve our knowledge, an intensive systematic survey (ISOTAN-DRAGA I Project), was conducted by the author from depths extending from the shallow sublittoral to 3180 meters (MBT series). The research vessels used were the "Prof. W. Besnard" and "Emilia", of the Instituto Oceanografico, USP. The samples were collected with an MBT dredge (a small biological trawl modified by the author). The present paper is the first of a series to be published on the deep-sea isopods from that region. It reports three new bathyal species of Serolis Leach, 1818, namely S. insigttis sp. n., S. arcuata sp. n. and S. venusta sp. n. Serolis insignis sp. n. (figs. 1-11) Holotype.-Sta. MBT 168. Damaged female with developing oostegites, 11.0 mm in width (measured along pereonite I at the level of the postero-lateral angles). September 1970. P. Soares Moreira coll.

“…The study of the rich samples bearing isopods (sorting yet in progress) collected by the author through their ISOTAN-DRAGA 1 Program (MBT serie), has yielded both new records and many new species of the marine isopod genus SeroZis Leach, 1818 (Moreira 1966(Moreira , 1971a(Moreira , b, 1973(Moreira , 1974a. Additional material obtained through the GEDIP Program has contributed to enlarge our knowledge on the southern Brazilian serolid fauna, particularly from SeroZis exigua Nordenstam, 1933, p. 70-75, figs 17-18;Sheppard, 1933, p. 304-308, figs 9-10.…”

The following species of the isopod genus Serolis are recorded from the continental shelf of southern Brazil: S. exigua Nordenstam, 1933, S. polaris Richardson, 1911, S. foresti Bastida & Torti, 1970 and S. inermis sp. n. S. exigua is for the first time recorded from off Brazil. Both S. polaris and S. foresti are recorded from new localities. S. inermis sp. n., a new species, is detailed described. Remarks are made on the importance and variations of some morphological features. The limit of distribution of both S. exigua and S. foresti is slightly extended northernwards.

São assinaladas na plataforma continental centro-sul do Brasil as seguintes espécies de isópodes do gênero Serolis: S. exigua Nordenstam, 1933, S. polaris Richards on, 1911, S. foresti Bastida & Torti, 1970 e S. inermis sp, n. S. exigua é assinalada pela primeira vez ao longo do Brasil. Os registros de S. polaris e S. foresti representam novas localidades de ocorrência, S. inermis sp. n., espécie nova para a ciência, é detalhadamente descrita. São fornecidas informações adicionais sobre as espécies, assim como discute-se a variação e a importância de algumas características morfológicas. O limite Norte de ocorrência das espécies S. exígua e S. foresti é ampliado ligeiramente
