Habitat: Pseudolaguvia lapillicola, is described from southern Karnataka, Peninsular India. Description: It is similar to P. foveolata from West Bengal and the only other congener from Peninsular India, P. austrina, in having a rhomboid adhesive thoracic disc reaching posteriorly only to middle of pectoral-fin base, but is distinguished from these two species by details of body proportions. Colouration: It is distinguished from other congeners by its colour pattern consisting of a yellow brown ground colour with peppering of dark brown to black spots, two incomplete cream vertical bands restricted to ventral side of body and a crescentic mark at the base of the caudal fin separated from subdistal caudal fin blotches. Externally, these fish resemble members of the sisorid catfish genus Glyptothorax. Pseudolaguvia is diagnosed by the presence of a short thoracic adhesive apparatus with median depression; wide gill openings nearly meeting one another on the underside of the body; serrations on anterior margin of pectoral fin spine pointing toward tip; smooth to granulate anterior margin on the dorsal fin spine; slender body; papillate upper lip; and 8–10 anal fin rays. Both the dorsal fin and pectoral fin have strong spines. The head and body are slightly depressed. The eyes are small, dorsal, and located in the middle of the head. The barbels are annulated with black rings. Etymology: Pseudolaguvia, Pseudo-, false; i.e., although this genus may superficially resemble several “closely allied” genera, including Laguvia (a junior synonym of Erethistes), such an appearance is false. The species epithet lapillus, pebble; colere, to dwell, referring to the substrate of its habitat, including gravel and rounded stones.
