FIGURE 2. Dorsal view of left side of head of cleared-and-stained specimens, showing the difference in distribution of snout plates between a) Cordylancistrus santarosensis, AUM 52887, b) Chaetostoma platyrhyncha, ANSP 84570, c) Co. torbesensis, MCNG 8066, d) Ch. guariense, AUM 39880, and e) Ch. stanni, INHS 28838. Black line in a, d, and e represents the edge of the distribution of snout plates. The suspensorium has been removed from a, b, c, and e. Vertical bar represents 10 mm. Arrows point to where plates extend further towards the snout margin, between which there is a central region without plates at the extreme anterior edge of the snout (see Description). Photos by M.
