[1] A subsequent study by Thoni & Gurung in 2018 identified two specimens in the Bumdeling Wildlife Sanctuary in the northeast of Bhutan, expanding the previously known range of the species to throughout the upper Drangmechhu River.

[2] Parachiloglanis bhutanensis has a brown, somewhat translucent body, with a pale yellow head.

The head is broad, blunt, and rounded, rising out of the body at roughly a 45-degree angle from the snout.

[4] The first specimens of Parachiloglanis bhutanensis were discovered in the cascades of a small, fast-flowing stream, over 2,000 meters above sea level, while adhering to the underside of boulders.

Thoni & Gurung speculated that the species evolved to a high-speed environment with paired fins to cling to rocks and a mouth that adapted to scraping invertebrates from the bottom of the streams.
