| Diagnosis | Diagnosis. Sauresia cayemitae sp. nov. has (1) a dorsal pattern of absent/irregular flecks/lineate, (2) head markings absent/present, (3) markings in the longitudinal paramedian area present, (4) dots arranged in bars in the lateral band absent, (5) an adult SVL of 47.8–58.1 mm, (6) ventral scale rows, 101–119, (7) midbody scale rows, 31–37, (8) total lamellae on one hand, 15–19, (9) total strigae on ten scales, 84–104, (10) relative length of all digits on one hindlimb, 11.5–14.0 %, (11) relative distance between the angled subocular and mouth, 0.0558–0.473 %, (12) relative eye length, 2.14–2.90 %, (13) relative forelimb length, 9.65–12.5 %, (14) relative ear width, 0.294– 1.17 %, (15) relative rostral height, 1.65–2.73 %, (16) relative head length, 13.0–15.6 %, (17) relative mental width, 1.46–1.78 %, (18) relative postmental width, 2.27–2.51 %, (19) relative cloacal width, 5.59–6.24 %, (20) relative prefrontal width, 3.11–3.64 %, (21) relative largest supraocular width, 1.67–2.25 %, (22) relative longest finger length, 2.36–2.65 %, (23) relative distance between the ear and eye, 6.02–6.88 %, (24) relative head width, 68.5– 77.1 %, (25) relative frontal width, 71.3–83.1 %, (26) relative nasal height, 0.792–0.951 %, (27) relative angled subocular height, 0.740–1.02 %, (28) relative distance between the eye and naris, 2.86–3.51 %, (29) relative canthal iii length, 1.07–1.30 %, (30) relative angled subocular width, 1.88–2.17 %, and (31) relative nasal length, 1.06–1.46 %. The species stem time is 1.19 Ma and the species crown time is 0.18 Ma (Fig. 4). we distinguish Sauresia cayemitae sp. nov. from the other species of Sauresia based on a complex of traits. From Sauresia agramma sp. nov., we distinguish S. cayemitae sp. nov. by the ventral scale rows (101–119 versus 121–127) and the relative distance between the ear and eye (6.02–6.88 versus 6.93–7.86). From S. gracilis sp. nov., we distinguish S. cayemitae sp. nov. by the relative eye length (2.14–2.90 versus 2.97), the relative head length (13.0–15.6 versus 15.7), the relative postmental width (2.27–2.51 versus 2.76), the relative cloacal width (5.59–6.24 versus 7.18), the relative prefrontal width (3.11–3.64 versus 3.81), the relative largest supraocular width (1.67–2.25 versus 2.44), the relative longest finger length (2.36–2.65 versus 1.96), the relative distance between the ear and eye (6.02–6.88 versus 7.63), the relative head width (68.5–77.1 versus 67.6), the relative nasal height (0.792–0.951 versus 0.998), and the relative width of canthal iii (1.07–1.30 versus 1.82). From S. habichi, we distinguish S. cayemitae sp. nov. by the ventral scale rows (101–119 versus 122–125), the midbody scale rows (31–37 versus 38–41), and the relative head width (68.5–77.1 versus 77.7–78.6). From S. manicula sp. nov., we distinguish S. cayemitae sp. nov. by the adult SVL (47.8–58.1 versus 59.6–69.0), the ventral scale rows (101–119 versus 121–129), the total strigae on ten scales (84–104 versus 119–150), the relative postmental width (2.27–2.51 versus 2.13–2.16), and the relative longest finger length (2.36–2.65 versus 2.20–2.21). From S. pangnolae sp. nov., we distinguish S. cayemitae sp. nov. by the relative prefrontal width (3.11–3.64 versus 3.70–3.83) and the relative distance between the ear and eye (6.02–6.88 versus 6.94–7.46). From S. sepsoides, we cannot distinguish S. cayemitae sp. nov. based on our standard suite of characters (see Remarks). From S. synoria sp. nov., we distinguish S. cayemitae sp. nov. by the frontal width by the SVL (3.11–3.75 versus 3.78–4.32) (see Remarks).

| Comment | Similar species: Sauresia cayemitae sp. nov. and S. synoria sp. nov. can only be separated by the frontal width by the SVL (3.11–3.75 [n=7] versus 3.78–4.32 [n=2]). Sauresia cayemitae sp. nov. and S. sepsoides cannot be distinguished based on morphological characters (Schools & Hedges 2024). |
| Etymology | Named after the type locality, Grande Cayemite Island, Haiti. |
