FIGURE 4. M in Bryodiversity in the tropics: taxonomy of Microporella species (Bryozoa, Cheilostomata) with personate maternal zooids from Indian Ocean, Red Sea and southeast Mediterranean

FIGURE 4. M. coronata, specimens from Lebanon, SE Mediterranean. A: cleaned non-ovicellate zooid with 6 oral spines, paired avicularia and ascopore edged with a proximal bulge. B: uncleaned non-ovicellate zooid with long setiform mandibles. C: maternal zooid with peristomial collar including the ascopore and joined lateral flaps, and ovicell with vizor (proximal part of ectooecium) and nodular, pseudoporous wall (entooecium). D: secondary orifice of a maternal zooid with un-fused lateral flaps. E: ancestrula (to the left) with 10 spines. Scale bars: A–E = 100 µm.
