It is only known from two specimens collected near Banaue from Mountain Province in northern Luzon. Both were collected at 1,980 metres (6,500 ft) above sea level. Nothing else is known about this species, such as its habitat, and the holotype has since been lost.[2][1]

A 2017 phylogenetic study found Myersophis to be the sister group to the genus Oxyrhabdium (both genera having diverged during the Oligocene), and assigned both, alongside some other Philippine endemic snake genera, to the new subfamily Cyclocorinae. Later studies uplifted Cyclocorinae to being its own family, Cyclocoridae.[3]
