Schematic of the mouth of Peckoltia wernekei based on the specimen in Figure 3. Dentaries (D) form less than a 90° angle with one another whereas premaxillae (PM) are relatively straight. A broad, broken band is formed from ovate blotches (OB) on the upper lip, separated from a line that runs along the mesethmoid (ML) by a C-shaped light space (C).
