description: <i>Paraplanocera marginata</i> Meyer, 1922 (Fig. 10) <i>Paraplanocera marginata</i> Meyer, 1922: 139–145, pl. 1, figs 1–8, text figs 1–3a; Prudhoe, 1945: 195. <b>Material examined:</b> One specimen sagittally sectioned. AM W.50277 (16 slides). A specimen was collected from Australia, New South Wales, Toowoon Bay, rocky headland adjacent to SLSC, found under rocks, 33°21’47.01”S, 151°30’7.31”E. Coll. Jorge Rodriguez, Mandy Reid and Alison Miller, May 16 th, 2018. <b>Remarks:</b> The Toowoon Bay specimen agreed with the original species description by Meyer in 1922.Externally, <i>Paraplanocera marginata</i> Meyer, 1922 possesses a rounded body, a pair of nuchal tentacles and an orange yellow dorsal surface with scattered small white dots and a black marginal band with intermittent white streaks (Fig. 9A). Internally, the male copulatory system of <i>P. marginata</i> is characterised by the presence of a free prostatic vesicle provided with tubularly chambered glandular epithelium in its proximal region, two oval-shaped seminal vesicles, a cirrus lined with spines that grow larger distally, and the presence of an accessory prostatic vesicle at the distal end of the cirrus bulb. The female system is provided with a bursa copulatrix, cement glands grouped in two pockets, and a long Lang’s vesicle (Fig. 9B, C). Meyer (1922) described the marginal band of <i>P. marginata</i> as purple, while the one in the present specimen appeared black. Prudhoe (1989) notes that an individual of <i>P. marginata</i> from Australia was seen bearing a narrow submarginal black band, which matches that of the studied specimen. <b>Molecular remarks:</b> <i>Paraplanocera marginata</i> Meyer, 1922 appeared together with another specimen from Hawaii (USA) sequenced by Litvaitis <i>et al.</i> (2019) with high support (100/1.00). The <i>Paraplanocera</i> clade also appeared as the closest relative to the <i>Planocera</i> clade with high support (99/1.00) in the Planoceridae family. <b>Distribution:</b> Red Sea (Meyer 1922, type locality); Kenya, Africa and the Persian Gulf (Prudhoe 1945); USA, Hawaii (Litvaitis <i>et al.</i> 2019). <b>New record:</b> Toowoon Bay, New South Wales (Australia).
