Type locality. Katchall [island in Andaman and Nicobar Islands, India]. Type material. Holotype NHMUK 1888.8.6.31 (Figs 2F, 11L; H=38.4 mm, W=19.0 mm). Remarks. Godwin-Austen clearly stated that this taxon was described based on only one specimen. Therefore a single specimen ex. Roeepstorff (Fig. 2F) in the NHM collections is recognized as the holotype fixed by monotypy ( ICZN 1999 : Art. 73.1.2).
