Calyptooecia conuma Almeida & Souza, 2014

( Figs. 72–73 )

Calyptooecia conuma Almeida & Souza, 2014: 285 , figs. 2–5; Almeida et al. 2015b: 5.

Material examined. UFBA 1183 , Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Spongosorites sp.).

Remarks. Calyptooecia conuma is characterized by small spot-like colonies ( Fig. 72 ), brooding zooids without perioral tubercles, and non-brooding zooids surrounded by 4–5 conical tubercles and a single, asymmetrically placed, suboral avicularium on almost all zooids ( Fig. 73 ) ( Almeida & Souza 2014). Only two species of Calyptooecia are known worldwide ( Bock 2016). Calyptooecia insidiosa Winston, 1984 is found in the Caribbean where colonies are associated with coral undersurfaces and reef caves ( Winston 1984). Calyptooecia conuma commonly encrusts calcareous nodules, shells, coralline algae and sponges ( Almeida & Souza 2014). We examined a small colony attached to recesses of the rugose-textured sponge Spongosorites sp. ( Fig. 11 ).

Distribution. Atlantic: endemic to Brazil (Bahia) ( Almeida & Souza 2014).
