[[ Pareuchiloglanis Pellegrin ]]

Members of the sisorid catfish genus Pareuchiloglanis Pellegrin, 1936 are rheophilic catfishes chiefly found in the headwaters of major river drainages throughout South and East Asia. They belong to the sisorid subfamily Glyptosterninae, a group distributed from the Caucasus to China, and have been distinguished from other members of the subfamily by the presence of homodont dentition arranged in narrow bands with sides not extending posteriorly.

The monophyly of Pareuchiloglanis remains doubtful. He (1995, 1996) demonstrated the paraphyly of Pareuchiloglanis , Oreoglanis , and Pseudexostoma (possibly with the inclusion of Myersglanis and Parachiloglanis ) and a rediagnosis of glyptosternine genera is badly needed. However, that is beyond the scope of this study, and the current definition of Pareuchiloglanis is used here.

While examining material for a study on the phylogenetic relationships of glyptosternine genera, material from the Red River (Song Hong) drainage in northern Vietnam, and the Salween River (Nujiang) and Irrawaddy River drainages in southern China were found to belong to two undescribed species. The description of the Chinese material as Pareuchiloglanis macropterus sp. nov. and the Vietnamese material as P. rhabdurus sp. nov., brings the total number of currently accepted species in this genus to fifteen.
