Figure 5. Chrysemys corniculata sp. nov. plastron. A-C, C. corniculata sp. nov., holotype plastron (ETMNH-12491) in ventral view: A, line drawing of plastron in ventral view, with bones outlined in black and scutes with dashed outlines; B, plastron in ventral view; C, line drawing with scutes outlined in black and bones with dashed outlines, and arrow pointing to the concavity on the rim of the anterior plastral lobe with the anterior plastron projection anterior to this point. D, C. corniculata sp. nov., paratype plastron (ETMNH-20544) in anterior view highlighting the anterior plastral embayment. E-F, Chrysemys, anterior plastral lobe in dorsal (visceral) view highlighting gular overlap length differences: E, C. corniculata sp. nov., holotype anterior plastron (ETMNH-12491) in dorsal view; F, C. picta anterior plastron (ETVP 9683) in dorsal view. Abbreviations: Bones: ent, entoplastron; epi, epiplastron; hyo, hyoplastron; hyp, hypoplastron; xi, xiphiplastron. Scutes (scales): ab, abdominal; an, anal; ax, axillary; fe, femoral; gu, gular; hu, humeral; in, inguinal; pe, pectoral. Features: guo, gular overlap. Scale bars: 5 cm for A-C, D-E and F.
