SYNOPSIS

The occurrence of Tosia parva (Perrier, 1881), Marginaster pectinatus Perrier, 1884 and Ldbidiaster radiosus Liltken, 1871 in the South Atlantic region is registered for the first time. The new varieties, Phrixometra longispina brasiliensis var. n., and Holothuria (Vaneyothuria) lentiginosa brasiliensis var. n., are de scribed. The genus Calliophidiaster Tommasi, 1970 is redescribed and its differences with Linckia Nardo, 1934, are reinforced. Ophiomyxa vivipara Studer, 1886 and Ophiura fallax Cherbonnier, 1959 are de scribed for the first time from Brazil. Amphiura iraciae sp. n. and A. rosae sp. n. are described.

SUMMARY

Some species of echinoderms, collected during the voyages of the R/V "Prof. W. Besnard", are discussed. Phrixometra longispinna brasiliensis var. n., is characterized by 30-32 cirri, 11-12 cirrais, 18 segments in the pinnules and by the second pinnular being as long as the first one. In four pinnules there is a well developed marsupium. Holothuria (Vaneyothuria) lentiginosa brasiliensis var. n., has corpuscules very similar to those of the Açorian specimens, but the colour is darker and the lateral papillae smaller. Tosia parva (Perrier, 1881), Luidia elegans Perrier, 1876, Marginaster peotinatus Perrier, 1884 and Labidiaster radiosus Lutken, 1871 are reported for the first time from the South Atlantic region. The genus CaVliophidiaster Tommasi, is redescribed, and its difference with Linckia Nardo, 1934, reinforced.

Keys are given for the Brazilian species of Goniasteridae and for the southwestern Atlantic species of Poraniidae.

Ophiomyxa vivipara Studer, 1886 and Ophiura fallax Cherbonnier, 1959, are reported for the first time from Brazil. The first is a subantarctic species and the second was formely known only from French Guiana. Amphiura iraciae sp. n. and A. rosa sp. n. are characterized by their shape, number of brachial spines, and by the number and shape of the tentacular scales.
