Zootaxa 2017 4290 2 281 323 [151,437,1907,1933] Gymnolaemata Marcusadoreidae Marcusadorea Animalia Cheilostomatida 22 303 Bryozoa species pinheroi sp. nov.    Material examined.  Holotype:  UFBA1186, Camamu Bay, 13°53’S, 38°59’W,  18–20 m, coll.  October2012(on sponge  Timeasp.).   Paratype:  UFBA1946, Salvador, Bahia,  Brazil, 12°57’S, 38°21’W, intertidal, coll.  April2012.  Typelocality. Camamu Bay,  BahiaState, NE Brazil.   Etymology.Named after Ulisses Pinheiro (Universidade Federal de Pernambuco), in recognition of his contribution to the knowledge of Brazilian biodiversity.   Description.Colony encrusting, spot-like, unilaminar. Colony pale yellow. Zooids semi-erect, large, globular, limited by raised distinct lateral walls. Frontal shield heavily calcified, granular, with small nodules of calcification, frontally punctured by 20–24 pseudopores except at the peristomial calcification that remains imperforate; marginally with a distinct row of 12–20 pores. Primary orifice large, hoof-shaped, with a pair of small lateral triangular condyles. Nooral spines. Secondary orifice raised, forming a well-developed tubular peristome with circular aperture that obscures the primary orifice, with same calcification as frontal shield but without pores; aperture oval in ovicelled zooids. Avicularia absent. Ovicell prominent; ooecia globose, 0.396 mmlong and 0.649 mmwide, same granular, nodular and porous calcification as in autozooids, opening into the peristome above zooidal operculum.   Remarks.Currently four  Marcusadoreaspecies are recognized—  Marcusadorea corderoi( Marcus, 1949),  Marcusadorea efatensis(Tilbrook, 2006),  Marcusadorea jamaicensis Vieira, Migotto & Winston, 2010and  Marcusadorea tubulosa( Canu & Bassler, 1928b).  Marcusadorea pinheroi  n. sp.most closely resembles  M. efatensisin having a frontal shield with numerous pseudopores, a subcircular primary orifice with small condyles, ooecia with tha same calcification as frontal shields, and no avicularia. Both differ, however, in the autozooids (semi-erect in  M. pinheroi  n. sp.and non-elevate in  M. efatensis), development of the peristome (conspicuous in autozooids and ovicelled zooids of  M. pinheroi  n. sp., and especially well-developed in ovicelled zooids of  M. efatensis), and the marginal pores (non-differentiated in  M. pinheroi  n. sp.and large and distinct in  M. efatensis). Other species of  Marcusadoreaare readily distinguished from  M. pinheroi  n. sp.in having suboral avicularia (that are absent in  M. pinheroi  n. sp.), frontal walls with scattered pseudopores (entirely punctured in  M. pinheroi  n. sp.), and forming a pseudosinus (absent in  M. pinheiroi).  Marcusadorea pinheroi  n. sp.is also the only species of the genus that has semi-erect autozooids. No information regarding substrate type used by Marcusodareaspecies was given, but  M. tubulosafrom NE Brazil is often seen on rocks and coral rubble (L.M. Vieira, unpub. data). Here we found colonies of  M. pinheroi  n. sp.attached to the smooth-textured surface of  Timeasp. ( Fig. 16).   Distribution.Atlantic: Brazil( Bahia). 1572325810 UFBA October 19 23 304 -13.883333 Camamu Bay 1289 -38.983334 22 303 UFBA 1186 1 holotype 1572325788 [368,817,151,176] UFBA El Salvador Bahia 23 304 UFBA 1946 1 Bahia paratype 1572325809 April Brazil -12.95 Camamu Bay 1291 -38.35 23 304 1 holotype 1572325804 [481,740,188,213] Brazil Bahia 23 304 1 Bahia holotype
