Description: Colonies stolonal, up to 455 µm high, arising from a creeping hydrorhiza that gives rise to short and narrow pedicels. Perisarc moderately thick and smooth. Each pedicel carries a hydrotheca. Hydrothecae cylindrical and elongated, 408–455 µm high, 114–157 µm wide. Hydrothecal wall smooth and with a thin perisarc. Margin smooth, straight, and rarely with renovations. Few hydrothecae with cracks in the edge. Diaphragm visible in few polyps, straight and moderately thick. Few hydranths were found, those partially degraded, but long and with six tentacles.

Material examined: PCS – two infertile colonies one from the dry season and the other from the rainy. CZUFS CNI-00141; CNI-00330.

Station: PCS – 5.

Bottom: sand.

Distribution: Brazil – Ceará ( Marques et al. 2006), Espírito Santo ( Vannucci 1949, 1951a, Grohmann et al. 1997, 2003), Rio de Janeiro ( Vannucci 1951a, Nogueira et al. 1997, Grohmann et al. 2003, Miranda et al. 2015), São Paulo ( Migotto 1996, Silveira and Morandini 2011, Miranda et al. 2015), and Santa Catarina ( Shimabukuro 2007, Miranda et al. 2011, 2015, Denise M.
