Etymology. The specific name ��� gemarita ��� is a combination of the name ��� gemar ��� (short name of the GEociencias MARinas (Marine Geoscience) research group of the Instituto Espa��ol de Oceanograf��a, and ���- ita ��� (in Latin suffix that means ���belonging to���), in honour of the scientists and students of the GEMAR research group who helped in the INDEMARES CHICA project. Description. Colony encrusting, uni- to multilaminar. Autozooids large, oval, distinct by shallow grooves between thin, raised rims, not disjunct (Fig. 3B, C). Gymnocyst absent; cryptocyst narrower distally and laterally, more developed and asymmetrical proximally, very finely crenulated. Opesia occupying three quarters of the frontal area (Fig. 3B, C). One small, interzooidal avicularium usually located at the proximal corner of each zooid, in the angular interzooidal spaces, with each autozooid surrounded by six avicularia (Fig. 3B, C). Rostrum elongate-oval, rounded and slightly broader at the tip, sometimes serrated, variably directed, without crossbar (Fig. 3C). Large interzooidal avicularia not observed. Ovicell endozooecial, cap-shaped, extending beneath the cryptocyst of the distal zooid (Fig. 3D). Remarks. Thirty-four species of Antropora have been described around the world, and most of them are fossil (Bock 2019; accessed 02.12.2019). Among the Recent species, two of them��� A. compressa (Osburn, 1927) and A. minor (Hincks, 1880b) ���resemble Antropora gemarita Ramalho & L��pez-F�� n. sp. The former species was de- scribed from the Caribbean Sea and has zooids disposed very close to each other without indication of an interopesial area. It also has interzooidal avicularia similar in shape but distally directed (in A. gemarita Ramalho & L��pez- F�� n. sp. avicularia are variably directed), and smaller autozooids (300���400 ��m long x 200���300 ��m wide) (Osburn 1927). The latter species has similar cryptocyst appearance, but smaller zooids (320���500 ��m long x 150���350 ��m wide) (Tilbrook 1998), and a single avicularium (40���90 ��m long). Habitat and associated species. This species was found on MDACs intermixed with coarse sediment dominated by sponges and coral rubble (mainly of M. oculata). It was also found in sandy mud with MDACs, sponges (Asconema setubalense Kent), small gorgonians (Acanthogorgia hirsuta Gray or Swiftia sp.), and echinoderms (C. cidaris and L. phalangium).
