Pareuchiloglanis is a genus of sisorid catfishes native to Asia.

These species are rheophilic catfish chiefly found in the headwaters of major rivers in South and East Asia.

Four species are known from the (upper Mekong River) drainage of China: P. abbreviatus, P. gracilicaudata, P. myzostoma and P.

[4] The premaxillary tooth bands in the catfish tribe Glyptosternina are important in identifying genera; in Pareuchiloglanis, the tooth band is divided into two patches, appearing in two types.

[3] There are currently 20 recognized species in this genus: Pareuchiloglanis species have an interrupted groove behind their lips (post-labial groove), gill openings not extending onto the underside (venter), homodont dentition of pointed teeth in both jaws, tooth patches in the upper jaw joined into a band and not produced posteriorly at sides, and 13–16 branched pectoral rays.
