Sisoridae is a family of catfishes. These Asian catfishes live in fast-moving waters and often have adaptations that allow them to adhere to objects in their habitats. The family includes about 235 species.
The family Sisoridae is recognized as a natural, monophyletic group based on morphological and molecular evidence. It is divided into two subfamilies, Sisorinae and Glyptosterninae (glyptosternoids). The Sisorinae contain the five genera Bagarius, Gagata, Gogangra, Nangra, and Sisor. The Glyptosterninae contain three tribes. Glyptothoracini contains only the genus Glyptothorax and Pseudecheneidina contains only the genus Pseudecheneis. The remaining genera, Chimarrichthys, Exostoma, Glaridoglanis, Glyptosternon, Myersglanis, Oreoglanis, Parachiloglanis, Pareuchiloglanis, and Pseudexostoma, are contained in the tribe Glyptosternina. The monophyly of the entire family and the tribe Glyptosterninae are well supported by osteological morphology and molecular data.
In the genera Glyptothorax (tribe Glyptothoracini) and Pseudecheneis (tribe Pseudecheneidina), the species have thoracic adhesive apparatuses to attach to objects in the stream bed; in Glyptothorax, grooves of this apparatus run parallel or oblique to the axis of the body, while in Pseudecheneis grooves run transverse to the axis of the body. The thoracic adhesive apparatus is not present in the other sisorid genera. The paired fins may be plaited to form an adhesive apparatus in Pseudecheneis, glyptosternoids, and variably in Glyptothorax. Thus, glyptosternoids lack a thoracic adhesive apparatus, but do have plaited paired fins, and members of the subfamily Sisorinae lack either a thoracic adhesive apparatus or plaited paired fins.
