Pristimantis angustilineatus is a species of frog in the family Strabomantidae. It is endemic to Colombia and known from the Cordillera Occidental in Chocó, Risaralda, and Valle del Cauca Departments, at elevations of 1,700–2,500 m (5,600–8,200 ft) asl.^[3]^[4] The specific name angustilineatus refers to the narrow white dorsolateral lines and comes from Latin angustus (="narrow") and lineatus (="of a line").^[2]
