Abstract

Hanguana bakoensis is described as a new species from Bako National Park, Sarawak, Malaysian Borneo. The confused taxonomic history of Hanguana is highlighted and species-level taxonomically important characters are enumerated. A key to the currently recognized Hanguana species of Borneo is provided, and the new species is illustrated.
