dc:title"An overview on the freshwater sponge fauna (Demospongiae: Spongillida) of New Zealand and New Caledonia with new insights into Heterorotula from deep thermal vents of the Lake Taupo";
dc:description"Figure 1. (A) Study area of Spongillida (Porifera, Demospongiae) in insular freshwater of Australasia. (B) New Caledonia Island harbours three endemic species viz. Heterorotula caledonensisı Oncosclera diahoti, and Pachyrotula raceki (genus Pachyrotula is also endemic). Heterorotula multidentata is shared by New Caledonia and Eastern Australia. (C) Geographic range of Heterorotula kakahuensis endemic to New Zealand.";

(C) gemmule with spicular cage.(D) foramen. (E–F) close-up on the distal rotules of gemmuloscleres in the trilayered gemmular theca (FW- POR 428, FW-POR 429).";

dc:description"Figure 5. (A), Morphotraits of Heterorotula kakahuensis (as Ephydatia kakahuensis, New Zealand) vs Ephydatia fluviatilis (eastern Europe, original plate after Traxler 1896). E. kakahuensis 1–2, gemmule and detail of foramen, 5–8, long birotules as gemmuloscleres, 9–11, spiny oxeas as megascleres. E. fluviatilis 3–4, gemmule and detail of foramen, 12–14, short birotules as gemmuloscleres. Not to scale. (B) Ephydatia kakahuensis (modified after Schröder 1935). (Ba) megascleres. (Bb) gemmuloscleres (lateral view). (Bc) gemmuloscleres (top view); the gemmuloscleres are very similar to those of several other species of Ephydatia. Not to scale.";
