Not explicitly given, “Sarawack auf Borneo”, by implication based on the title of the paper, now State of Sarawak , Borneo , Federation of Malaysia . — Syntypes in Genova Museum. Comments. This taxon was synonymised with Lachesis wagleri by Boulenger (1896: 562) . Status. Taxon here regarded as a subjective synonym of Tropidolaemus subannulatus ( Gray, 1842 ) , but available, as Tropidolaemus ( subannulatus ) immaculatus , for any population inhabiting Borneo which would prove to be potentially distinct from Tropidolaemus subannulatus .
