Poricella frigorosa Winston, Vieira & Wollaccott, 2014
(Figs. 34–35)
Poricella frigorosa Winston, Vieira & Wollaccott, 2014: 186, fig. 30. Poricella mucronata: Almeida et al. 2015b: 4.
Material examined. UFBA 1585, Todos os Santos Bay, 13°00’S, 38°32’W, 3–8 m, coll. 2013 (on sponge Callyspongia sp.); UFBA 2066, UFBA 2388, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Myrmekioderma sp.).
Remarks. Poricella frigorosa has encrusting colonies (Fig. 34), autozooids with 3–4 orificial spines, an anchor-shaped frontal mucro, a central cluster of two or three round to oval pores, large interzooecial avicularia with a typically straight and pinched distal margin, and with a densely calcified ooecia opening above the operculum (Fig. 35) (Winston et al. 2014). Poricella frigorosa is part of the Poricella mucronata (Smitt, 1873) species complex (Winston et al. 2014). Until the description of P. frigorosa, P. mucronata and Poricella sp. were the only species recorded from the Brazilian coast (Vieira et al. 2008; Almeida et al. 2015b). Part of these specimens may also belong to P. frigorosa. No information about the substrata of the specimens reported from Brazil was given. Species of Poricella are known to encrust other bryozoans, coral skeletons, red algae, lava boulders and serpulid tubes (Tilbrook et al. 2001; Berning 2006; Dick et al. 2006; Moissette et al. 2007).
Distribution. Atlantic: endemic to Brazil (Bahia and Rio de Janeiro) (Winston et al. 2014).
