Stylopoma hastata Ramalho et al., 2018: p. 168, fig. 5C–E.

Material examined. MNRJBRY-1453, MNRJBRY-1474, MNRJBRY-1494, MNRJBRY-1495: Brazil, Maranhão state (Sta #7, 00°14.742’S – 044°54.089’W), 23 m, on sponges, 29 September 2014; MNRJBRY-1460, MNRJBRY- 1549: Brazil, Pará state (Sta#6, 00°45.359’N – 046°38.49’W), 50 m, on rhodoliths, 29 September 2014; collected by Fernando Moraes & Rodrigo Moura (NHo Cruzeiro do Sul).

Distribution. Known from Maranhão and Pará states in Northern Brazil (present study), and Abrolhos Bank, Bahia state, Brazil (Ramalho et al. 2018).

Remarks. Stylopoma hastata Ramalho et al., 2018 was originally described from the Abrolhos Bank, Bahia state, Brazil, based on non-ovicellate material. Northern Brazil specimens allow the first description of ovicells (Fig. 8C–E), which are globose [L 321–380–408 (SD 34, N 8); W 330–418– 501 µm (SD 50, N 8)] with ooecial surface similar to the frontal shield of autozooids, evenly perforated by small pseudopores at the centre of polygonal depressions; small triangular avicularia [L 47–51– 58 µm (SD 6, N 3)] (similar to those observed on the autozooids) are found on the ovicell surface; the aperture consists in a crescentic lumen formed by the fusion of the labellum at the center, arising from the proximal edge (Fig. 8D–E). The figures also show the characteristic elongate avicularia (Fig. 8C, F).
