Brazilian Miocene crabs I. Taxonomic review of Cyclocancer tuberculatus Beurlen, 1958 and Hepatella amazonica Beurlen, 1958 (Pancrustacea, Decapoda, Brachyura)

In describing Cyclocancer to accommodate his new species C. tuberculatus, Beurlen highlighted that his new genus was a cancroid intermediate in form between Atelecyclus and Cancer, but with enough characters to be placed in a new genus. Examination of C. tuberculatus type material revealed that Cyclocancer is a junior synonym of Hepatus. Therefore, C. tuberculatus is herein transferred into Hepatus as H. beurleni nomen novum because H. tuberculatus (Beurlen, 1958) is a junior homonym of H. tuberculatusSaussure (1858), a junior synonym of Hepatus pudibundus (Herbst, 1785). Miohepatus gen. nov., comb. nov. is proposed here to accommodate Hepatella amazonica Beurlen from the Pirabas Formation, Neogene, Pará, Brazil, based on new morphological evidence from the type material.(AU)

New or little known demosponges (Porifera) from Espírito Santo coast and seamounts (Brazil)

Phorbas capixaba sp. nov. is described from 54 m depth off Guarapari, diagnosed by its two clear-cut categories of isochelae from Phorbas spp. known from the Western Tropical Atlantic. Four nomina nova are proposed for homonyms in Phorbas spp.: P. bergmontae nom. nov. for P. areolatus Bergquist & Fromont, 1988, preoccupied by P. areolatus (Thiele, 1905); P. burtoni nom. nov. for P. arborescens sensu (Burton, 1956), preoccupied by P. arborescens (Ridley, 1884); P. hechteli nom. nov. for P. ramosus (Hechtel, 1983), preoccupied by P. ramosus (Lendenfeld, 1888; in part - composite species); P. tanitai nom. nov. for P. purpureus (Tanita, 1961), preoccupied by P. purpureus (Carter, 1886). Three little known species are redescribed: Aplysina alcicornis Pinheiro et al., 2007; Mycale (Aegogropila) escarlatei Hajdu et al., 1995 and Yucatania sphaeroidocladus (Hartman & Hubbard, 1999). All three are new records for Espírito Santo. The first and the last of these are range extensions, while the other fills a distribution gap. A list of sponges hitherto recorded from off Espírito Santo state, with indication of the bibliographic source of the record is given in appendix. In total, 118 species were compiled from 23 publications.
