03E787EDFFCCFFA83D93430E6C04D4CD.taxon	description	Description. Colony encrusting, unilaminar to multilaminar. Autozooids rectangular to irregularly polygonal (Figs 2 A, 3 A), limited by shallow lateral walls (Figs 2 B, 3 B). Frontal shield with some small granules of calcification on the surface (Fig. 3 B), 66 – 106 frontal small pseudopores varying in size throughout the colony, often placed in irregularly polygonal deep cavities on the zooidal surface (Fig. 2 B, C), and distinctly large, elongated marginal pores with secondary calcification; umbo absent. Primary orifice with anter transversely D-shaped (Figs 2 B, C; 3 B), wider than long, with a smooth distal rim and poster with a wide and deep U-shaped median sinus (0.032 – 0.049 mm length x 0.026 – 0.041 mm width) about 1 / 3 of the orifice length; a pair of slightly projected square condyles (0.008 – 0.014 mm length x 0.014 – 0.022 mm width), with smooth margins. Secondary orifice slightly raised, with nodular calcification around the primary orifice (Fig. 3 B). Adventitious avicularium small (0.051 – 0.075 mm length x 0.035 – 0.054 mm width) (Figs 2 B, C; 3 B), single or paired, placed proximolateral to the orifice or sub-oral (Figs 2 C; 3 B), distolaterally oriented; 1 – 2 frontal avicularia, placed below the orifice (Fig. 2 B) or adjacent to the zooidal margins, irregularly oriented; avicularia with subtriangular rostrum, a thin and complete crossbar and an elliptical foramen. Vicarious avicularia large (0.366 – 0.449 mm length x 0.105 – 0.137 mm width) (Figs 2 D; 3 C), sometimes larger than the autozooid, rostrum sublanceolate (but sometimes almost panduriform); palate incomplete medially and distally, fusing at the distal third and leaving a median and a distal foramen; foramen elliptical and elongated; complete crossbar. Vicarious kenozooids may be present between autozooids (Fig. 3 A). Ovicells prominent (Figs 2 E, F; 3 D – F), obscuring the orifice of the maternal zooid; ooecium globose, slightly flattened frontally (Fig. 3 E), with more pseudopores compared to the frontal shield; one to four small adventitious avicularia of the same morphology as the others on the ooecial surface (Figs 2 E, F; 3 D – F); opening of the ooecium semicircular, with a joined proximal labellum (Fig. 3 E, F).	en	Rodrigues, Maria J.

03E787EDFFCCFFA83D93430E6C04D4CD.taxon	discussion	Remarks. In some colonies of Stylopoma anacarolinae sp. nov., most autozooids lack adventitious avicularia, which may represent ontogenetic variability (Fig. 3 A). In these colonies, orifice and sinus shapes serve as useful characters to give a more confident identification. Autozooids of S. anacarolinae sp. nov. have an orifice with a D-shaped anter and poster with a U-shaped sinus, a characteristic shared with ten other Stylopoma species. However, S. anacarolinae sp. nov. is distinguished from other species with a U-shaped sinus in having a pair of squared condyles. Among the species described from Brazil, at least four, namely S. aurantiacum, S. hastata, S. multiavicularia and S. variabilis, have orifices with a U-shaped sinus. Besides differences in the shape of the condyles (triangular in S. hastata, and subrectangular in S. aurantiacum, S. multiavicularia and S. variabilis), these species are distinguished from S. anacarolinae sp. nov. by the width of the sinus, which is broader in Stylopoma anacarolinae sp. nov. compared to the congeners (Canu & Bassler 1928 a; Ramalho et al. 2018; Rodrigues et al. 2020). Morphologically, S. faceluciae, described from Brazil (Costa dos Coqueiros and Todos os Santos Bay; Rodrigues et al. 2020) resembles S. anacarolinae sp. nov. due to the presence of an orifice with squared condyles and sublanceolate vicarious avicularia. However, it can be distinguished from the latter by the shape of the sinus (teardrop-shaped in S. faceluciae and broadly U-shaped in S. anacarolinae sp. nov.).	en	Rodrigues, Maria J.

03E787EDFFC7FFA53D9340AE6E3AD331.taxon	discussion	Remarks. The holotype here described and figured consists of the sole colony of S. priscilae sp. nov. (with fragmented pieces) found among over 5,000 bryozoan specimens collected by the ‘ Akaroa’ and ‘ Canopus’ from NE Brazil. The autozooids of S. priscilae sp. nov. have an orifice with anter D-shaped and poster with a teardrop-shaped sinus, a characteristic shared with twelve other species of Stylopoma. However, S. priscilae sp. nov. is distinguished from other species with a teardrop-shaped sinus by having a pair of tab-like condyles occupying most of the proximal border on each side of the sinus. Among the species described for Brazil, at least three, S. corallinum, S. faceluciae and S. rotundum, have orifices with a teardrop-shaped sinus. In addition to the differences in the shape of the condyles (rectangular in S. corallinum and squared in S. faceluciae and S. rotundum), these species are distinguished from S. priscilae sp. nov. by the adventitious avicularia (acute-subtriangular in S. priscilae sp. nov., rhombic in S. corallinum; subtriangular in S. faceluciae and elliptical in S. rotundum) (Winston et al. 2014; Rodrigues et al. 2020). Among the remaining Stylopoma species worldwide, at least nine, S. haywardi Winston & Woollacott, 2009, S. horarium Tilbrook, 2006, S. inchoans Tilbrook, 2000, S. informata, S. lacrima Tilbrook, 2001, S. magnistilla Tilbrook, 2001, S. magnovicellata Silén, 1954, S. smitti and S. spongites, have an orifice with a teardrop-shaped sinus. Stylopoma priscilae sp. nov. is distinguished by having an orifice with tab-like condyles (rectangular in S. haywardi, S. horarium, S. inchoans, S. informata, S. lacrima and S. magnistilla; subrectangular in S. smitti and S. spongites) and a large acute-subtriangular adventitious avicularium (short and subtriangular in S. magnovicellata) (Di Martino 2023; Tilbrook 2000, 2001, 2006; Winston 2005; Winston & Woollacott 2009; Rodrigues et al. 2020). Morphologically, S. multiavicularia, described from Brazil (Costa dos Coqueiros, Bahia; Rodrigues et al. 2020) resembles S. priscilae sp. nov. as it is the only other species in Brazil with a subtriangular acute adventitious avicularium. However, it can be distinguished by the teardrop-shaped sinus (U-shaped in S. multiavicularia).	en	Rodrigues, Maria J. S., Larré, Igor R. N. M., Vieira, Leandro M.
