Since the only place where this snake is found is in the Kapuas River, the longest island river in Southeast Asia, located in West Kalimantan, it is named Kapuas mud Snake. This species was discovered in 2005. The specific name, gyii, is in honor of Burmese herpetologist Dr. Ko Ko Gyi.

The upper body is grayish black, earth brown or blackish red. The sides of the body and under the body is light brown or orange. This coloration is similar to the coloration pattern of Homalophis doriae (Sarawak mud snake).

Very little information about the Kapuas mud snake. This snake is only known as a water snake and lives on the banks of rivers. Until now, there is no more accurate information about the life of this snake in nature. 

The unique and rare feature of this snake is its ability to change color. This ability was discovered by accident in 2005, when Mark Auliya, a collector, put the snake in a dark box. Before the snake was placed in the bin, its scales were still red and black, but after 20 minutes, the snake’s skin had turned white.
