Identification Dolichancistrus is similar to Leptoancistrus, Cordylancistrus and Chaetostoma. Dolichancistrus is differentiated from Leptoancistrus by the presence of the adipose and anal fins (vs. their absence); from Cordylancistrus and Chaetostoma by the presence of pectoral-fin spines in mature males longer than those in adult females and immatures of both sexes (vs. the pectoral spines of equal length in both sexes); and from most species of Chaetostoma in having a plated snout (vs. naked). Dolichancistrus differs from Chaetostoma platyrhynchus in having the hyperthrophied cheek odontodes evertible to more than 90º (vs. evertible only to approximately 30-40º) and in bearing hyperthrophied cheek odontodes that are distally recurved (vs. odontodes straight along their entire length).

This species sports large white spots which become more widely spaced with age.
General Remarks L 442 is known from the Río Meta drainage in the area of Villavicencio. L225 is only recorded as "Colombia".
