The purpose of this application, under Articles 12 and 75.3 of the Code, is to conserve the long and continuing usage of the specific name wagleri for a Southeast Asian species of venomous snake by ruling that the specific name Cophias wagleri was established by F. Boie (1827). This would involve setting aside all previous usages of that name and designating a neotype. As originally proposed by Schlegel (1826) Trigonocephalus [Cophias] wagleri is a replacement name for Coluber sumatranus Raffles, 1822 but the Commission is now asked to rule that this name denotes a separate taxon. These actions are required to avoid synonymy between the two specific names and between the generic names Tropidolaemus Wagler, 1830 and Parias Gray, 1849.
