( Fig. 4A, B View FIGURE 4 ; Table 5)

Holoporella mordax   MARCUS, 1937A: P. 123, PL. 24, fIg. 65A –F.

Celleporaria mordax   : WINSTON et al., 2014: P. 195, fIg. 36 (CUM SYN.).

Material examined. UFBA 1639, UFBA 1655, UFBA 3321, UFBA 3322, on valves of Pinctada imbricata   .

Description. Colony encrusting ( Fig. 4A View FIGURE 4 ), unilaminar. Autozooids irregularly shaped, surrounded by few large marginal pores. Frontal wall imperforate, rough, with small nodules. Primary orifice ( Fig. 4B View FIGURE 4 ) D-shaped, with a small, U-shaped sinus ( occasionally with two indentations); 2–4 oral spines. Suboral avicularium small, elliptical, rostrum serrated, obliquely oriented within the peristome. Interzooidal avicularium large, spatulate, with beak-like rostrum and complete crossbar. Ovicell not observed.

Remarks. This species is frequently found subtidally on hard substrata in southeastern Brazil ( Winston et al. 2014). This is the first record of C. mordax   from northeastern Brazil.

Distribution. Western Atlantic: Brazil ( Bahia, Rio de Janeiro and São Paulo) ( Winston et al. 2014; present study).
