Distribution of Pseudemys peninsularis and the study area.
(A) Distribution of P. peninsularis across the world. The red star indicates the location of South Korea. (B) Jeonpyeongje Neighborhood Park with the nest sites indicated by the yellow stars. (C) A nest with P. peninsularis eggs. (D) Map of South Korea with study site at Gwangju indicated by a green star. The maps and satellite images were generated using Arcmap 10.8.1 (ESRI, USA; https://support.esri.com/en/products/desktop/arcgis-desktop/arcmap/10-8-1).

Identification of the samples.
(A) Phylogenetic tree based on mitochondrial DNA control region. Nodal support values placed before ‘/’ are Bayesian Posterior Probabilities (BPP), and values placed after ‘/’ are Maximum Likelihood Bootstraps (BS). In our tree ‘*’ denotes greater or equal to 0.95 BPP and 70% BS, ‘#’ denotes 0.85–0.94 BPP and 60–69% BS, and ‘–’ denotes below 0.85 BPP and 60% BS. The numbers in the parentheses correspond to the serial number of Table 1. The bold fonts indicate the de novo sequences. (B) Pairwise genetic distance (p-distance). We excluded the outgroup from the calculation. The numbers correspond to the serial number of Table 1. (C) Dorso-lateral view of a hatchling of Pseudemys peninsularis. (D) Ventral view of a hatchling of P. peninsularis.

Egg shapes and eggshells of freshwater turtles found in South Korea.
(A) Pseudemys peninsularis; (B) P. concinna; (C) Trachemys scripta; (D) Graptemys ouachitensis; (E) G. geographica; (F) Chrysemys picta; (G) Chelydra serpentina; (H) Mauremys reevesii. The eggs without outlines indicate parchment shells and the egg with a black outline indicates a brittle shell.
