Sigmaxinella cearense sp. nov. is described here on the basis of a single specimen collected in 2004 at Parque Estadual Marinho da Pedra da Risca do Meio, off Fortaleza, Ceará, Brazil. This is the first record of Sigmaxinella for the Atlantic Ocean. The new species differs from the other eleven Sigmaxinella species by the absence of raphides/microxea, and is the only species with a single category of styles as megascleres (mean length 435µm, mean width 12µm), and sigmas (mean length 21µm). The new species appears to be closer to Australian species of Sigmaxinella, on the basis of overall spicule morphology (mainly dimensions and categories of megascleres). This could be suggestive of a transpacific track for the colonization of the South Atlantic, instead of the shorter Agulhas track.Key words: Sigmaxinella, taxonomy, Parque Estadual da Pedra da Risca do Meio, sponge, new species, sandstone reef, Brazil

As part of the sampling efforts during the DIVA-II expedition several Tanaidacea of the genus Neotanais were captured in the Guinea and the Cape Basin in the tropical and southern East Atlantic Ocean. Two different species were sampled, Neotanais rotermundiae sp. n. from the Guinea and Neotanais guskei sp. n. from the Cape Basin. The distribution of both species is limited to these basins. A full description for both species is presented. Neotanais guskei sp. n. is the largest Neotanais reported for the South Atlantic Ocean.

A New Species

AbstractThe present study describes a new species, Ligophorus uruguayense, parasitizing the gills of Mugil platanus Günther, 1880 from the coast of Uruguay. It differs from all other species of the genus mainly in the shape of the ventral bar, the thick process at the distal end of the inner root of ventral anchors, the J-shaped penis accessory piece and the vaginal tube showing transverse annulations at its distal end, the host species, and geographical distribution. This is the first description of a species of Ligophorus from a mullet in the South Atlantic Ocean.

The nudibranch Flabellina dana Millen and Hamann, 2006 is reported from two localities in the northeastern Brazilian coast. These are the first records of this species, previously recorded from localities in the Bahamas and the Caribbean Sea, in South Atlantic Ocean, extending its known geographic distribution more than 3500 km southward.

Three New Species

Three new species of myxosporeans are described from the gall bladders of Lophius piscatorius L. and L. budegassa Spinola. Ceratomyxa lophii n. sp. was found in 14 of 42 L. piscatorius from two locations to the northwest of Scotland in March 2000. Alataspora budegassai n. sp. was found in all eight specimens of L. budegassa caught off Algarve in the south of Portugal in June and August 2000. Pseudalataspora lophii n. sp. was found in 21 of 48 L. piscatorius from six locations to the west and northwest of Scotland in March 2000, March 2004 and October 2004. Ceratomyxa lophii n. sp. is one of only a few species of the genus having unequal spore valves, but differs from all the other species in spore dimensions and in the form of the plasmodium. The dimensions of the spore of Alataspora budegassai n. sp. are very similar to those of A. africana Shulman, Kovaleva & Dubina, 1979, described from a species of perciform fish caught off West Africa, but are markedly different from those of any of the other 15 described species of Alataspora. Pseudalataspora lophii n. sp. differs from the other 11 species of Pseudalataspora described to date in the dimensions of the spore and other features.
