Found in Eastern Thailand, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins.

The type specimen was collected by the first author in Khao Yai National Park (Nakhon Ratchasima Province) at an elevation of 1,430 m (4,690 ft).

[1] The lichen has a shiny, finely warted (verruculose) thallus with a poorly developed cortex and a white medulla.

Its ascospores are thin-walled, somewhat translucent to brown, and spindle-shaped (fusiform), typically measuring 204.5–252.5 long by 17.5–25.5 μm wide.

The lichen contains norstictic acid, a secondary compound that is rare in the genus Myriotrema.
