Microporella ichnusae sp. nov. from the Iberian-Provençal Basin, NW Sardinia, Capo Caccia-Isola Piana MPA, Bisbe Cave, Holotype PMC. B30a. 20.11.2020 A colony portion with broken ovicells, autozooids showing evidences of reparation, and kenozooids with (white asterisk) and without (black asterisk) avicularia B autozooids with complete or broken ovicells C paired autozooids, seemingly repaired, one lacking avicularium D close-up of a colony portion with evidence of zooidal repair. Note the occluded orifice indicated by the partly protruding spines (see arrow) E group of zooids (two ovicellate), some with open or closed mandibles and one lacking an avicularium F close-up of two zooids. Owing to the absence of an ascopore, which is usually placed at the same level as the avicularium, the upper one is more likely to be a kenozooid equipped with an avicularium than an autozooid with obliterated orifice. Note also the different frontal shield texture of its proximal margin, likely due to ovicell resorption G close-up of an autozooid with sealed orifice (central zooid), and an orifice with a thin secondary rim, indicating intramural budding presumably as a result of predation. Scale bars: 500 µm (A); 200 µm (B–G).
