Kobelt 1902 : 131. Type locality. Molu Hills [Sarawak, Malaysia]. Type material. Holotype NHMUK 1998011 ( Fig. 16B; D =39.1 mm, H=23.3 mm, W=4). Remarks. Godwin-Austen clearly stated that this taxon was described based on only one specimen, therefore we recognise this specimen as the holotype fixed by monotypy ( ICZN 1999 : Art. 73.1.2).
