FIGURE 19. Exechonella catalinae n. sp. Red Sea (A, C, F: paratype DPUV 2012-0002-0006, Northern Bay of Safaga; B, D: E, paratype DPUV 2012-0002-0007, Northern Bay of Safaga; G, H: IPUW 7016, Jeddah). A, G, general colony view from above. B, close-up of two zooids showing details of primary orifice and peristomes. Three lateralmost foramina shown by arrows. C, D, lateral view of peripheral colony part showing shape of peristomes and multiporous mural septula. E, close-up of lateralmost foramen with avicularium associated with kenozooid in cleaned colony. Central nipple-like structure is surrounded by denticulate rim. Pores of kenozooid have centrally perforated cuticular plates. F, H, details of primary orifice and peristome. Scale bars: A, C = 1 mm; B, D‒F = 100 µm; G = 2 mm; H = 400 µm.
