DistributionDominican Republic

Type locality: Palace Hotel in Ciudad Trujillo (= Santo Domingo), Dominican Republic  
Reproduction 
TypesHolotype: UMMZ 83305, an adult male, collected 7 May 1937 at the Palace Hotel in Ciudad Trujillo (= Santo Domingo), Dominican Republic, by Chester Roys.
Paratypes (n = 7). Dominican Republic. UMMZ 239592–98 (paratopotypes), same collecting data as holotype (UMMZ 239593–97 are fetuses from UMMZ 239592). 
DiagnosisDiagnosis. Mabuya hispaniolae sp. nov. is characterized by (1) maximum SVL in males, 86.6 mm; (2) maximum SVL in females, 92.6 mm; (3) snout width, 3.08–3.47% SVL; (4) head length, 17.7–19.2% SVL; (5) head width, 11.6–14.0% SVL; (6) ear length, 1.11–1.46% SVL; (7) toe-IV length, 10.7–11.1% SVL; (8) prefrontals, two; (9) supraoculars, three; (10) supraciliaries, four (75%), five (25%); (11) frontoparietals, two; (12) supralabial below the eye, five (50%), six (50%); (13) nuchal rows, one; (14) dorsals, 54–62; (15) ventrals, 67–76; (16) dorsals + ventrals, 123–138; (17) midbody scale rows, 30–32; (18) finger-IV lamellae, 13–14; (19) toe-IV lamellae, 16–19; (20) finger-IV + toe-IV lamellae, 30–33; (21) supranasal contact, N; (22) prefrontal contact, N; (23) supraocular-1/frontal contact, Y; (24) parietal contact, Y; (25) pale middorsal stripe, N; (26) dark dorsolateral stripe, N; (27) dark lateral stripe, Y; (28) pale lateral stripe, Y; and (29) palms and soles, dark (Tables 3–5).
Within the Genus Mabuya, M. hispaniolae sp. nov. is separated from M. cochonae sp. nov., M. desiradae sp. nov., M. grandisterrae sp. nov., M. guadeloupae sp. nov. and M. montserratae sp. nov. by having a longer frontonasal scale (frontonasal length 20.5–23.9% head length versus 16.5–19.9% in those other five species; Fig. 34). It is distinguished from M. dominicana, M. grandisterrae sp. nov., M. guadeloupae sp. nov., and M. mabouya by having a longer supraciliary-2 scale (supraciliary-2/supraciliary-3 length ratio 1.43–1.49 versus 1.67–2.40 in those other species; Fig. 36). Mabuya hispaniolae sp. nov. additionally differs from M. dominicana by having a wider supranasal scale (supranasal length/width 3.41–4.15 versus 4.57–6.57 in M. dominicana; Fig. 35). It also has a wider snout than M. dominicana (snout width 17.4–18.0% HL versus 13.6–17.5% in M. dominicana; Fig. 40) and a less dorsoventrally compressed head (not measured). Mabuya hispaniolae sp. nov. (visible in the holotype) differs from M. mabouya by having a pale lateral stripe bordered below by a narrow dark line (versus no border in M. mabouya). From M. montserratae sp. nov. it is also distinguished by having a smaller ear (ear length 1.11– 1.46% SVL versus 1.49–1.55% in M. montserratae sp. nov.). Mabuya hispaniolae sp. nov. also tends to have fewer midbody scale rows than M. montserratae sp. nov., 30 (six individuals) and 32 (two) versus 32 (four individuals) and 34 (four), and the fetuses of M. montserratae sp. nov. are spotted and lack dark dorsolateral stripes whereas the fetuses of M. hispaniolae sp. nov. have dark dorsolateral stripes, at least anteriorly [HEDGES & CONN 2012]. 
CommentAbundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe species name (hispaniolae) is a feminine genitive singular noun, referring to the distribution of the species on the island of Hispaniola.
