This species may be "the most extremely cave-adapted trechine" beetle in the world, morphologically adapted to life in the darkness of the caves of southern China.

[2] Its physical characteristics most resemble the beetle genera Giraffahaenops and Dongodytes.

Like Giraffahaenops, Xuedytes bellus has a thin and elongated body.

The genus Xuedytes differs from both of the aforementioned genera in its prothorax, which is longer than its head, its narrow elytra, and the right mandibular tooth shows an evolutionary adaptation.

It is characterized as having a yellowish brown body, with tarsi, palps, and antennae pale, and a strongly shining head.
