FIGURE 7 | Pelvic girdle and caudal skeleton in c&s paratypes of Corydoras maclurei (CITL 430). A. Anterior internal process of basipterygium slightly laterally expanded, and anterior external process not expanded posteriorly (38.2 mm SL); B. Anterior internal process of basipterygium conspicuously laterally expanded, and anterior external process slightly expanded posteriorly (47.8 mm SL); C. General morphology of caudal skeleton, showing the small cartilage (yellow arrow) between upper principal and procurrent caudal-fin rays (38.2 mm SL). Abbreviations: bp: basipterygium, ccc: compound caudal centrum, cfr: caudal-fin principal rays, dpcr: dorsal procurrent rays, epu: epural, has: haemal spine, hyp 1–5: hypurals 1 to 5, nes: neural spine, pae: anterior external process, pai: anterior internal process, par: parhypural, pi: dorsal ischiac process, pu 2–4: preural centra 2 to 4, un: uroneural.
