Gemelliporina glabra ( Smitt, 1873) 

( Fig. 6AView FIGURE 6)

Gemellipora  forma glabra  (typica) Smitt, 1873: 37, figs 208–210.

Gemellipora glabra: Busk, 1884: 176  , fig. 3; Canu & Bassler, 1928b: 98, figs 1–7;

Gemelliporina glabra: Marcus, 1939  , fig. 14A, B; Osburn, 1940: 426; Winston, 2005: 89, figs 247–256; Vieira et al., 2008: 29; Almeida et al., 2015a: 5; Bastos et al., 2018: table 1.

Material examined. Abrolhos Bank, Bahia State, Brazil: MNRJ-Bry1348, California Reef, 25 m depth, March 2015, col. F.C. Moraes, R. Moura, G. Amado-Filho & A. Bastos. 

Short description. Fragments of erect colonies with zooids oval to claviform, without visible demarcation between adjacent zooids, which may be a preservational artefact; frontal wall with sparse pores and granular calcification; orifice keyhole-shaped; scattered oval avicularia observed on the frontal surface ( Fig. 6AView FIGURE 6).

Geographic distribution. Gulf of Mexico. Brazil: Pernambuco, Bahia and Espírito Santo states ( Busk 1884; Canu & Bassler 1928; Marcus 1939, 1955; Almeida et al. 2015a; Bastos et al. 2018; present study).

Remarks. Three species have been assigned to Gemelliporina  : G. hastata Winston & Woollacott, 2009  , G. punctata ( Canu & Bassler, 1929)  and G. glabra ( Smitt, 1873)  (bryozoa.net; accessed 01.03.2018). Gemelliporina glabra  is distinguished from G. punctata  and G. hastata  principally because these species have peristomial avicularia. The Abrolhos specimen was found at 25 m deep inside the reef matrix.
