Etymology: Paulasquama: Name from the Latin ‘paulus’ for small, and ‘squama’ for scale armor, referring to the small plates located in the dorsal series just below the dorsal fin.; callis: Name from Latin 'Callis' (masculine or feminine) for a stony, uneven, narrow footway, referring to the plates like cobblestones along the narrow mesethmoid with naked areas to either side; noun in apposition..

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 2; членистые (мягкие) лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи анального плавника: 5. This species is distinguished from all other hypostomines by three unique autapomorphies: large, oval area lateral to the mesethmoid that is devoid of plates; plates in the dorsal series lateral to dorsal fin reduced to less than half what would be expected for a loricariid of its size; and, a fleshy keel along and slightly anterior to the preadipose plate and extending to dorsal caudal-fin simple ray along dorsal procurrent rays (Ref. 86603).
The collection area Waruma is a largely clearwater river with a slight black tint. Specimens
collected in a riffle, in a shallow side channel over polished cobble and gravel with some larger rocks covered in a grasslike vegetation. The watershed is forested (Ref. 86603).
