Labioporella tuberculata Winston, Vieira & Woollacott, 2014
(Fig. 2B)
Labioporella tuberculata Winston et al., 2014: 144, figs 2, 3; Vieira et al., 2016: 75, figs 32–34; Bastos et al., 2018: table 1.
Material examined. Abrolhos Bank, Bahia State, Brazil: MNRJ-Bry1337, Parcel dos Abrolhos, 15 m depth, February 2014, col. R. Moura, G. Amado-Filho & A. Bastos.
Short description. Colony encrusting, autozooids rectangular with rounded distal edges, disposed in quincunx and separated from each other by a raised edge. Cryptocyst granular and porous. A pair of tubercles frequently present at the proximal corners. Avicularia absent in this material.
Geographic distribution. Alagoas and Bahia states (Vieira et al. 2016; Bastos et al. 2018; present study).
Remarks. Specimens found at Abrolhos were very similar to those described by Winston et al. (2014) and Vieira et al. (2016). Labioporella tuberculata resembles L. dipla Marcus, 1949, also described from Brazil (Espírito Santo State), but L. dipla has a prominent tubercle on the distal wall beneath the operculum, smaller zooids and lacks tubercles at the proximal corners of the zooids. Another similar species is L. granulosa (Canu & Bassler, 1928b), described from the Gulf of Mexico, which also lacks corner tubercles.
