FIGURE 22. Alyonushka filia n. gen., n. sp. A–E, G–L, holotype, ZIRAS 1/50710; E, F, paratype, NIWA 127724. A, frontal (apical) view of colony showing two gonozooids separated by a narrow cleft, each chamber with an ooeciopore (arrows); B, oblique view of A from 8 o'clock perspective, showing two gonozooid mounds separated by cleft (concealed in furrow), each mound with complex spiky alveolate surface; C, same, from different angle, cleft at middle left; D, autozooidal peristomes with linear ridges and barbs, and pores; E, skeletal microstructure of gonozooid surface; F, I, incompletely developed autozooidal peristomes with abundant internal spinules; G, close-up of part of cleft between adjacent gonozooids; H, base of colony with hummocks indicating underlying alveolar/kenozooid-like chambers; note densely prickled surface; J, L, ooeciostomes of the two gonozooids shown in A; K, apical view of mature autozooidal peristome. Scale bars: A, 500 µm; B–D, H, 250 µm; F, G, I, J, L, 100 µm; E, K, 50 µm.
