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. 6A ). 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.
