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.
