Glaridoglanis verruciloba, a new species of glyptosternine catfish, is described from the Zayul River in southeastern Tibet. The authors note this newly described species has long been misidentified as Glaridoglanis andersonii (which had been assigned to Exostoma) previously (Gong Z. et al. 2025). Habitat: This species is presently known only from the Zayul River (= upper Lohit River) drainage, a tributary of the Brahmaputra River, south-eastern Tibet, China. It occurs mainly in mountain streams and is less frequently found in the river mainstem. At the type locality during sampling period, the water temperature was 4.1–7.5 °C, the dissolved oxygen was 9.46–12.58 mg/L, and the pH was 7.86–8.32. Sympatric fishes mainly included Creteuchiloglanis kamengensis (Jayaram, 1966) and Schizothorax molesworthi Tsao, 1964 (Gong Z. et al. 2025). Colouration. In life, dorsal and lateral surfaces yellow brown; ventral surface pale pink; ventral surface of the first rays of pectoral and pelvic fins faintly pink; all fins with yellowish distal margins. In 70% ethanol, head and dorsum pale grey, ventral region dark yellow; dorsal, anal, and caudal fins yellowish grey; dorsal surfaces of pectoral and pelvic fins yellowish grey, ventral surfaces dark yellow. Etymology: The genus name Glaridoglanis: glarídos, genitive of glarís, chisel (tool), allusion not explained, presumably referring to truncate or notched teeth of G. andersonii; glánis, ancient name for a silurid catfish (probably Silurus aristotelis) dating to Aristotle, often used as a general term for catfish. The specific name: verruciloba: Derived from the Latin verruca (= wart) and lobus (= lobe), referring to the verruciform lobes on the central-posterior margin of lower lip. As Glaridoglanis is feminine (fide Kottelat 2013), the specific epithet is treated accordingly. The Chinese common name of this species is (Yóu yè záo chi zhào), which literally means “wart-lobed chiseled-tooth catfish”.
