Glaridoglanis verruciloba sp. nov., a new glyptosternine catfish (Siluriformes, Sisoridae) from the Zayul River in southeastern Tibet, China.

Glaridoglanis verruciloba sp. nov. is described from the Zayul River in southeastern Tibet, China. It has long been misidentified as G. andersonii. This new species is diagnosed by the following combination of characters: an enlarged lower lip bearing 4-7 verruciform lobes on the central-posterior margin; an anus situated close to the origin of the anal fin; the ventral surface at the base of maxillary barbels densely covered with striae; 11 branched pectoral-fin rays; 5-6 branched anal-fin rays; and relatively short mandibular barbels. Molecular phylogenetic analyses of mitochondrial cytochrome b sequences further supported the validity of this new species, which is within a well-supported clade with substantial genetic divergence from G. andersonii.
