Skeletons in confusion: a review of astrophorid sponges with (dicho-) calthrops as structural megascleres (Porifera, Demospongiae, Astrophorida) Author Van Soest, Rob W. M. Author Beglinger, Elly J. Author De Voogd, Nicole J. text ZooKeys 2010 68 1 88 http://dx.doi.org/10.3897/zookeys.68.729 journal article http://dx.doi.org/10.3897/zookeys.68.729 1313-2970-68-1 Stoeba natalensis Burton, 1926 Stoeba natalensis Burton 1926 : 14. Material examined. None. Description (from Burton, 1926). Encrusting on Stelletta specimens. Dry condition. Skeleton made up by radially arranged dichotriaenes with rhabd (720 x 54 µm ) approx. twice as long as the cladome (approx. 360 µm ), making them long-shafted triaenes rather than dichocalthrops. Microscleres are called ataxasters 'passing into tuberculate microrhabds' , 5-8 µm long. Habitat. Deeper water. Distribution. Natal coast, South Africa. Remarks. This is a dubious Dercitus (Stoeba) species and it needs redescription. Probably it should be assigned to an ancorinid genus. Family Calthropellidae
