| Distribution | Dominica Type locality: Dominica |
| Reproduction | viviparous (not imputed, fide Zimin et al. 2022) |
| Types | Lectotype: MCZ R-6049 (paralectotypes, MCZ R-185619–20), collected by Samuel Walton Garman on Dominica, March, 1879. |
| Diagnosis | Diagnosis: Mabuya dominicana is characterized by (1) maximum SVL in males, 92.3 mm; (2) maximum SVL in females, 101 mm; (3) snout width, 2.41–3.45% SVL; (4) head length, 16.4–20.9% SVL; (5) head width, 11.5– 15.4% SVL; (6) ear length, 0.771–1.82% SVL; (7) toe-IV length, 8.91–13.4% SVL; (8) prefrontals, two; (9) supraoculars, three (60%), four (40%); (10) supraciliaries, three (2%), four (86%), five (11%), six (2%); (11) frontoparietals, two; (12) supralabial below the eye, five (70%), six (28%), seven (2%); (13) nuchal rows, one (98%), two (2%); (14) dorsals, 54–63; (15) ventrals, 63–73; (16) dorsals + ventrals, 118–136; (17) midbody scale rows, 27–32; (18) finger-IV lamellae, 12–16; (19) toe-IV lamellae, 15–19; (20) finger-IV + toe-IV lamellae, 27–34; (21) supranasal contact, Y (52%), N (48%); (22) prefrontal contact, N; (23) supraocular-1/frontal contact, Y (59%), N (41%); (24) parietal contact, Y; (25) pale middorsal stripe, N; (26) dark dorsolateral stripe, Y (14%; but only as a thin line on nape), N (86%); (27) dark lateral stripe, Y; (28) pale lateral stripe, Y (84%), N (16%); and (29) palms and soles, dark (Tables 3–5). Within the Genus Mabuya, M. dominicana differs from all other species by having a longer, narrower supranasal scale (supranasal length/width 4.57–6.57 versus 3.13–4.28 in those other species; Fig. 35). It is also separated from M. montserratae sp. nov. and M. hispaniolae sp. nov. by having a higher supraciliary-2/ supraciliary-3 length ratio (1.77–2.30 versus 1.39–1.66 in those two species; Fig. 36). It differs from M. cochonae sp. nov., M. desiradae sp. nov., M. grandisterrae sp. nov., and M. guadeloupae sp. nov. by having a longer frontonasal (frontonasal length 20.5–23.1% head length versus 17.8–19.9% in other species; Fig. 34). It differs from M. hispaniolae sp. nov. by having a narrower snout (snout width 13.6–17.5% HL versus 17.4–18.0% in M. hispaniolae sp. nov.; Fig. 40). Except for Mabuya guadeloupae sp. nov., M. dominicana has the best-developed stripes in the genus (Fig. 32). These include dark lateral and ventrolateral stripes, dorsolateral and pale lateral stripes (pale lateral stripes in 84% of specimens), and (occasionally) traces of narrow dark dorsolateral stripes on the nape (Fig. 32C). These stripes are evident in some fetuses (Fig. 39D), although M. hispaniolae sp. nov. has lateral dark and pale stripes that are nearly as well-developed [HEDGES & CONN 2012]. |
| Comment | Synonymy: GÜNTHER 1888 synonymized M. dominicana with M. mabouya, but subsequent authors recognized it again (or didn’t). |
| Etymology | The species name (dominicana) is a feminine singular noun, referring to the distribution of the species on the island of Dominica. |
