Reptadeonella leilae Almeida, Souza, Sanner & Vieira, 2015c: 362 , figs. 33–36, 42 (cum syn.).

Material examined. UFBA 1174 , Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Halichondria sp.).

Remarks. Reptadeonella leilae is characterized by unilaminar encrusting colonies ( Fig. 36 ), autozooids with a tubular peristome, a circular spiramen and no avicularia ( Fig. 37 ) ( Almeida et al. 2015c). The species grows on small substrata such as calcareous nodules ( Almeida et al. 2015c). Other Reptadeonella species are frequently found encrusting rocks, other bryozoans, calcareous nodules and algae, corals and shells (e.g., Marcus 1939; Soule 1961; Winston 1982b; Hayward & Ryland 1999; Tilbrook et al. 2001; Tilbrook 2006; Winston & Vieira 2013; Almeida et al. 2015c). Reptadeonella leilae was found attached to the smooth-textured sponge Halichondria sp., representing the first record of an association with sponges in the genus.

Distribution. Atlantic: endemic to Brazil (Bahia) ( Almeida et al. 2015c).
