APPENDIX 1. — Measurements (in mm) and biometric indices of the trunk vertebrae of Vipera cf. latastei Boscá, 1878 (COLT), mainland Vipera latastei (IMEDEA 106925 and MNHN-ZA-AC-2020-1), and Vipera latastei ebusitana Torres-Roig, Alcover & Bailon, 2020. Data of mainland V. latastei and V. l. ebusitana obtained from Torres-Roig et al. (2020). Abbreviations: σ, standard deviation; CL, vertebral centrum length, measured ventrally and including the condyle; CL/NAW, ratio between the length and the width of the neural arch; CTH, cotyle height; CTW, cotyle width; CTW/CTH, ratio between width and height of the cotyle; CTW/ NAW, ratio between cotyle width and the width of neural arch; Max, maximum value; Min, minimum value; N, number of specimens; NAW, width of the neural arch, measured at the maximum interzygapophyseal constriction; PO-PO, width of the external borders of the articular surfaces of the postzygapophysis; POPO/NAW, ratio between the width of the external borders of the articular surfaces of the postzygapophysis and the width of the neural arch; PR-PR, width of the external borders of the articular surfaces of the prezygapophysis; PR-PR/NAW, ratio between the width of the external borders of the articular surfaces of the prezygapophysis and the width of the neural arch; ZW, zygosphene width; ZW/NAW, ratio between the width of the zygosphene and the width of the neural arch.
