Etymology: Transancistrus: Derived from the Latin word 'trans', meaning across, over, or on the other side of, in reference to the distribution of this genus across rivers draining the Pacific slope of the Andes Mountains in Ecuador, and 'ancistrus', a root name for many Hypostominae genera having clusters of enlarged evertible cheek odontodes.; santarosensis: Named for its type locality, the Rio Santa Rosa (Ref. 89823).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Tropical
South America: Known only from the type locality, the Río Santa Rosa (Gulf of Guayaquil drainage) near the southern coast of Ecuador.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 8 - 9; Anal soft rays: 6. Can be diagnosed from all other members of the Chaetostoma group by having plates on the tip of the snout (except for a central region at the extreme anterior edge), but lacking plates laterally on the head (Ref. 89823).
