FIGURE 16. Exechonella azeezi n in Revision of the Recent species of Exechonella Canu & Bassler in Duvergier, 1924 and Actisecos Canu & Bassler, 1927 (Bryozoa, Cheilostomata): systematics, biogeography and evolutionary trends in skeletal morphology

FIGURE 16. Exechonella azeezi n. sp. (A‒G: A, IPUW 7544; B, G, paratype DPUV 2012-0001-0008; C, IPUW 7543; D, IPUW 7545, non-cleaned; E, F, paratype DPUV 2012-0001-0007 (all from Red Sea). H, I: D, IPUW 7546; I, D, IPUW 7013 (both from Maldive Islands)). A, general view of the part of colony from above. B, close-up of three zooids. Some lateralmost foramina with avicularia shown by arrows. C, lateral view of the peripheral part of the colony, showing peristome shape and multiporous mural septula. D, lateralmost foramen with avicularium. Arrowhead shows an edge of mandible. E, close-up of lateralmost foramen with avicularium associated with kenozooid (below). Pores of kenozooid have centrally perforated cuticular plates, larger marginal pores are seen laterally. F, G, close-up of two autozooids showing details of primary orifice and peristome. In F kenozooid (k) associated with avicularium (arrowhead) is visible to the left. H, general view of six peripheral autozooids from above. Some lateralmost foramina with avicularium shown by arrows. I, young colony of three autozooids and kenozooid (below). Supposed ancestrula is to the left. Scale bars: A = 1 mm; B, C, F, G, I = 100 µm; D, E = 10 µm; H = 500 µm.
