FIGURE 2. Hippopleurifera barbosae sp. nov. Specimens: A, MG–6301–I–a; B, MG–6301–I–b; C, MG–6301–I–d; D: MG– 6301–I–c; E: MG–6301–I–e; F: MG–6301–I–f. A, general view of colony fragment showing primary orifices, some lateral and suboral avicularia and one ovicellate zooid. B, general view of colony fragment with ovicellate zooids showing their major characteristics. C, detail of two autozooids showing primary orifices with condyles, lyrulate processes and distal spines, as well as suboral and lateral avicularia and frontal shields with areolar pores. D, ovicellate and non-ovicellate zooids. E, detail of a perforated bifenestrate oecium with two frontal avicularia. F, frontal-shield interiors showing openings of areolar pores and reduced umbonuloid areas (best seen in zooid at upper left). Scale bars: A, B, D, F, 500 µm; C, 200 µm; E, 150 µm.
