Pilumnus labyrinthicus Miers, 1884 , by original designation. Remarks . Of the five Vellumnus species originally recognised, Ng (2010) expressed doubt about the assignment of V. vermiculatus (A. Milne-Edwards, 1873 ) to this genus stating that it may require transferring to Lophoplax Tesch, 1918 . Examination of type specimens as well as material from the West Pacific were examined and the carapace characters show it is closer to Lophoplax , notably in the hepatic, gastric, and intestinal regions being swollen and setae covering the surfaces around them (see also Maenosono, 2019 ; Trivedi et al., 2022). It has since been transferred to this genus ( Ng and Rahayu, 2023 ).
