| Popis: | JANUSYA INDICA SP. NOV. (FIGS 5, 6; TABLE 2) Zoobank registration: urn:lsid:zoobank.org:act: 79DA23AC-B3EE-42B0-8BB3-1DA5F592AF9A. Etymology: Named in reference to the type locality located in the Indian Ocean. Diagnosis: Yellowish to beige Janusya in which the cormus is incrusting to globulose, formed by regular and tightly anastomosed tubes with long, apical, water-collecting tube. The skeleton contains fusiform diactines, trichoxeas, triactines and rare tetractines. Type locality: Passe de l���Hermitage, La R��union, Indian Ocean. Type material: Holotype ��� UFRJPOR 8945 (= 171109- PAE2 - TP20). Paratype ��� UFRJPOR 8932 (= 171109- PAE2 - TP6). Passe de l���Hermitage Reef, La R��union, Indian Ocean, coll. T. P��rez, 9 November 2017, 18��� 20 m depth. A d d i t i o n a l m a t e r i a l e x a m i n e d: U F R J P O R 8 9 3 1 (= 1 7 1 1 0 9- PA E2 -T P 5), U F R J P O R 8 9 4 0 (= 171109-PAE2-TP16). Passe de l���Hermitage Reef, La R��union, Indian Ocean, coll. T. P��rez, 9 November 2017, 18��� 20 m depth. Colour: Sponge yellowish beige in life (Fig. 5A, B) and light brown in ethanol (Fig. 5C, D). Morphology and anatomy: Sponge incrusting to globulose (Fig. 5). Cormus clathroid, formed by regular and tightly anastomosed tubes (Fig. 5). One or few apical oscula, surrounded by membrane (Fig. 5A). The osculum is a long water-collecting tube, i.e. a larger tube with osculum that receives the water from several other thinner tubes. Underneath the osculum of globulose specimens, there is a cavity that is not lined by a continuous membrane. Cells with yellow granules are present and distributed homogeneously in the mesohyl of the specimens UFRJPOR 8945 and UFRJPOR 8932 (Fig. 6A, B, respectivelly). The aquiferous system is asconoid and the skeleton is composed of diactines, trichoxeas, triactines and rare tetractines (Fig. 6C���F).
