New records and a new species of Serolis (Crustacea, Isopoda, Flabellifera) from southern Brazil

This paper reports on part of the species of the marine isopod genus Serolis (Crustacea, Flabellifera, Serolidae) collected from benthic stations performed during one of the cruises of the Brazil ian Navy Oc/S "Almirante Saldanha" along southern South America. The species reported are Serolis polccris Richardson, 1911, Serolis elliptica Sheppard, 1933, Serolis uaperta Moreira, 1971, and Serolis foresti Bastida & Torti, 1970. A complete synonymy is given for each of these species, as well as the main distinctive characteristics enabling its ready recognition. Some remarks are provided on features not lengthned treated on previous accounts. The geographi cal distribution of all named taxa is given. Serolis uaperta is for the first time reported from off State of Rio Grande do Sul (Brazil) and Uruguay, extending considerably southernwards its southern limit of distribution. Both Serolis foresti and Serolis elliptica are also for the first time recorded from off Uruguay.

The biological aspects of incubating females of Janaira gracilis Mbreira & Pires, are described. The marsupium is formed by 4 pairs of oostegites arising from pereopods I-IV. The oostegites appear for the first time at the post-marsupial stage 7 (preparatory stage 1), growing successively at each moult until stage 9 (brooding stage 1), when they reach fully development. The sizes of the eggs increase with the body size of the females. The number of eggs, per female, is a linear function of the body volume, i.e., the fecundity increases with the female's body size. The number of eggs, embryos and juveniles decrease during the marsupial development. This decrease in brood number is higher between the last two marsupial stages, i.e., from stage C to D, than between the preceding marsupial stages. The average and overall brood mortality rate is of 38.95%.
