Local inhabitants have accessed the cave. The underground river is connected to the Erdao River, a tributary of the Chishui River. This is the first occurrence of a stygobitic species of Triplophysa within the Chishuihe River basin, indicating a healthy ecological environment in the region.</p><p>Etymology.</p><p>The specific name refers to the type locality (county) of the new species: Dafang County and the Latin suffix (ensis).
