Figure 7. Chrysemys carapace comparisons, focusing on the morphology of the anterior edge. A-D, Chrysemys corniculata sp. nov. carapace in dorsal view: A, C. corniculata sp. nov., holotype carapace (ETMNH–12491); B, C. corniculata sp. nov. paratype carapace (ETMNH–20609); C, C. corniculata sp. nov., paratype carapace (ETMNH-20544); D, C. corniculata sp. nov., paratype carapace (ETMNH-3559), with arrow pointing to nuchal horns that occupy the anteromedial portion of marginal 1. E-I, C. picta anterior carapace morphology: E, female C. picta nuchal (UF 48670) in dorsal view; F, male C. picta nuchal (UF 49963) in dorsal view; G, male C. picta anterior carapace (ETVP 9683) in dorsal view with arrow pointing to the marginals 1 portion of the nuchal where the nuchal horns are present as an inconspicuous anterior projection; H, male C. picta anterior carapace with an arrow pointing to the lighter-coloured anterior projections of marginal 1 that would lie above the nuchal horns; I, female C. picta anterior carapace showing no anterior projections. Scale bars: A-D, 5 cm; E-G, 1 cm; H-I, not to scale.
