Cordylancistrus has historically been the bin into which ichthyologists placed all 'Chaetostoma-like' loricariids that had fully-plated snouts but lacked the distinctive attributes of either Dolichancistrus (long pectoral-fin spines, at least one highly elongate cheek odontode) or Leptoancistrus (adipose and anal fins missing, at least one highly elongate cheek odontode) (Lujan, Nathan 2019). Habitat: This species is endemic to Colombia and is present in the Dagua River and Upper Cauca basins. In Valle del Cauca, it has been reported from the rivers San Cipriano, Agua Clara and Anchicayá (Maldonado-Ocampo et al. 2005). It also occurs in Rio San Juan. In Antioquia, it has been reported from Alto Río Nechí. Its type locality is Caldas (Eigenmann 1912). Etymology: The genus name Cordylancistrus: From the 'Kordyle' = Club, swelling + (Greek) agkistron = hook, referring to its wide head. The specific name daguae: of the Dagua River basin, Colombia, where it is endemic. Remarks: Cordylancistrus daguae has a wide range; it occurs in several rivers. Although the population is affected by several threats, especially water pollution related to urban waste and mining, it seems to be relatively abundant where it occurs in Río Dagua. However, it is not known whether there have been population declines in other parts of its range. The species is listed as Least Concern, but a re-assessment should be performed once further population data are available (IUCN 2016).
