description: <i>Notoplana longiducta</i> Hyman, 1959 (Fig. 16) <i>Notoplana longiducta</i> Hyman, 1959: 10, figs 12, 13. <i>Notoplana longicrumena</i> Prudhoe, 1982: 369–370, fig. 4. <i>Notocomplana longiducta</i> Faubel, 1983: 114. <b>Material examined:</b> One specimen sagittally sectioned. AM W.53210 (4 slides). A specimen was collected at low tide under rocks from Australia, New South Wales, Bottle &amp; Glass, 33°50’53.9”S, 151°16’12.3”E. Coll. Jorge Rodriguez and Justin McNab, October 25 th, 2019. Additional material from Australia, New South Wales, Long Reef from the collections of the Australian Museum: AM W.3693 (holotype), W.3694. <i>Notoplana longicrumena</i> Prudhoe, 1982. One specimen from the collections of the Australian Museum, sagittally sectioned. AM W.53211 (8 slides). The specimen was collected from Australia, Tasmania, Pirates Bay Reef, March 7 th, 1958. Additional material from Australia, South Australia, Point Brown from the collections of the South Australian Museum: AHC.42652–42668 (holotype). <b>Remarks:</b> Externally, <i>Notoplana longiducta</i> Hyman, 1959 possesses an elongated body shape with a pale brown dorsal colouration, a transparent body margin and an anteriorly positioned pharynx (Fig. 16A–D). Internally, <i>N. longiducta</i> is characterised by the presence of a seminal vesicle, interpolated prostatic vesicle lined with tubularly chambered glandular epithelium, a very elongated penis stylet and a simple female system with a vertically oriented Lang’s vesicle (Fig. 16E–I). Hyman (1959) mentions the poor state of the male copulatory system in the histological sections and the difficulties it caused in reconstructing its anatomy. In the original description Hyman (1959) describes <i>Notoplana longiducta</i> as having an elongated and pointed penis papilla; however, a revision of the type material made clear that what was described as a penis papilla was in fact a fold of the male atrium (Fig. 16I). Hyman (1959) mentions not only that the histological sections are in poor condition but that the cuts were not performed in an exact sagittal plane, which explains the misidentification of this trait. It was also apparent in both the holotype and the specimen from Bottle &amp; Glass that this species presents a stylet in its male copulatory organ, although it was overlooked in the original description due to the poor condition of the type material (Fig. 16I). Faubel (1983) transferred <i>Notoplana longiducta</i> to the new genus <i>Notocomplana</i> created for <i>Notoplana</i> species not bearing a stylet. However, a re-examination of the holotype and new material revealed the presence of such trait in the male copulatory organ. As such, the present species was transferred back to <i>Notoplana</i> under the original combination <i>Notoplana longiducta.</i> Prudhoe (1982) described the new species <i>Notoplana longicrumena</i> from Point Brown, South Australia based on the presence of a long and slender penis stylet. Re-examination of the type material showed that the internal anatomy was identical to that of <i>N. longiducta</i> in light of the new description (Fig. 16G). As such, the primary authority belongs to Hyman (1959) and <i>N. longicrumena</i> was synonymised with <i>N. longiducta</i>. <b>Distribution:</b> Australia: New South Wales, Long Reef (Hyman 1959), South Australia, Point Brown (Prudhoe, 1982). <b>New record:</b> Australia, Tasmania, Pirates Bay Reef.
