Batavia, Ida Pfeiffer (Musée de Vienne). Unspecified number of ♂. Attems (1899) redescribed this species but did not explicitly refer to type specimens in the NHMW. No specimens found in the MHNG. The NHMW contains a single broken ♂ type specimen (Inventory number 2117, Acquisition number 1866.I.172). The Acquisition Register shows that the lot contained only one specimen, so this can be considered the holotype. The generic placement follows Jeekel (2007) . Gigantorhacus pfeifferae ( Humbert & Saussure, 1869 )
