Etymology: Chauliocheilos: Derived from a combination of the Greek chaulios (conspicuous, outstanding, prominent), and cheilos (lip), in reference to the labial appendix; saxatilis: From the Latin adjective saxatilis, meaning that lives on rocks, in reference to the microhabitat where the species is mainly collected. An adjective.

شعاع نرم باله پشتي (کل) : 8 - 9; شعاع نرم باله مخرجي: 6 - 7; مهره ها: 31. Chauliocheilos saxatilis is distinguished from all species of the Loricariidae by its unique labial appendix at laterodorsal portion of lower lip, associated to the proximal region of insertion of the maxillary barbel, in females above 3.24 cm SL and in males above 3.0 cm SL, but always much more developed in males, in which the appendix is highly grooved and can be very elongated posteriorly, surpassing the anterior portion of pectoral girdle. It differs further from all members of Hypoptopomatinae by the possession of 2 additional series of lateral plates on the body, one between the dorsal and mid-dorsal series with 2 to 16 plates, and the other between the mid-ventral and ventral series with 2 to 11 plates. Additional characters useful to identify this species within Hypoptopomatinae include the high number of lateral plates, mainly in the mid-dorsal (25-39) and mid-ventral series (28-41), lack of iris operculum, and the insertion of dorsal-fin posterior in the body, with the anterior portion of compound supraneural plus first dorsal-fin proximal radial contacting the neural spine of eighth vertebra (Ref. 98819).
The type locality is a very small stream, about 1 m wide, up to 30 cm deep, with a bottom consisting of gravel, pebbles, sand and clay, and besides trees and shrubs, with its margins composed of many specimens of Hedychium sp. (Zingiberaceae). This species was collected mostly in the bottom but also associated with vegetation at the margins. Other fishes found in the same stream include Astyanax fasciatus, Rhamdia cf. quelen, Rhamdiopsis sp., Trichomycterus jequitinhonhae and Trichomycterus sp. Based on four specimens ranging from 4.10-4.75 cm SL, food items in the stomach were mainly fine particulate organic matter and periphyton (unicellular algae, diatoms, zooplankton and microcrustaceans) (Ref. 98819).
