Size 160mm or 6.3" SL. Find near, nearer or same sized spp.
Identification The genus Chaetostoma is not straightforward to identify, but as a general rule, the species has spines behind the gill-cover (interopercular odontodes), no plates on the abdomen, and aside from C. platyrhynchus also lack plates on the snout edge. Different from Ancistrus by not having fleshy tentacles on the snout.

From Regan (1903): Head much depressed, without distinct ridges or prominences. Eye very small, its diameter 8 - 12 times in the length of head. Dorsal fin longer than high, the anterior rays scarcely longer than the posterior. Adipose fin usually rudimentary or absent. Pectoral spine barely reaching the root of the ventral. Caudal obliquely truncated. Scutes of body not keeled, with short marginal spines, about 26 in a longitudinal series. Olive-brown above with light spots, with light spots in some specimens; dorsal and caudal blackish, sometimes barred with light spots. Most similar to Chaetostoma microps.
Sexing Males develop cheek bristles and stay smaller and narrower than the more robust females.
