Phloeodictyon medium Topsent, 1928 : p. 321–322, pl. II, fig. 18, pl. X, fig. 27 (Azores). Oceanapia media ; Burton 1956 : p. 142 (genus transfer). Not Oceanapia media ( Thiele, 1899 ) (a valid species). Remarks. Thiele (1899) described Rhizochalina media from Indonesia . Topsent (1928) described a new species from the Azores as Phloeodictyon medium , the species was transferred to Oceanapia by Burton (1956) . When Van Soest (1980) proposed Rhizochalina as synonym of Oceanapia , he induced the homonymy between these species. According to the International Code of Zoological Name ( ICZN 1999: 52.2 ) the name of the species Oceanapia media ( Topsent, 1928 ) should be rejected. Oceanapia topsenti nom. nov. is herein proposed as a replacement name for Oceanapia media ( Topsent, 1928 ) homonymy of Oceanapia media ( Thiele, 1899 ) . Etymology. Named after Emile Topsent, who designated the species name.
