description
(FIGS 22, 23; TABLE 12) Synonyms: Leucettusa lancifer – Dendy, 1924: 278; Brøndsted, 1926: 301; Burton, 1929: 402; Burton, 1963: 555; Pritchard et al., 1984: 128; Kelly et al., 2009: 45; Leucettusa imperfecta – Burton, 1963: 598; Leucettusa lancifera – Kelly, 2018: 19. T y p e s p e c i m e n: O n e l e c t o t y p e (B M N H 1 9 2 3. 1 9. 1. 5) a n d o n e p a r a l e c t o t y p e (B M N H 1923.10.1.6). Type locality: Three Kings Islands, New Zealand (34 ° 24 ʹ S, 172 ° 06 ʹ E; inaccurate coordinates). Three Kings – North Cape MEOW ecoregion. Description: Sponge tubular with vase-shaped form, strongly oval at the top, tapering to the base. Colour white to beige in ethanol (Fig. 22 A). Consistency compressible to the touch. Outer surface smooth. Folds of choanosomal tissue delimitate the atrial cavity (Fig. 22 B). One apical osculum, elevated and surrounded by a membrane. Aquiferous system leuconoid with subspherical to oval choanocyte chambers (Fig. 22 C). Skeleton: Cortical skeleton well developed, having approximately the same thickness as the choanosome; comprised of several layers of tangential triactines (Fig. 22 D). Choanosomal and atrial skeletons reduced and comprised of pygmy triactines and tetractines mostly present around canals (Fig. 22 E, F). Pygmy tetractines are also abundant near the osculum.
