Type locality: between Killecrankie Mydram, Waterworks Estate, and Molyneux Village, Montserrat
|Types||Holotype: MCZ R-125464, an adult male, collected 6 August 1970 between Killecrankie Mydram, Waterworks Estate, and Molyneux Village, Montserrat, by J. Boos.|
Paratypes (n = 7). Montserrat. BMNH 126.96.36.199, F. Watts, no specific locality, accessioned 20 September 1894; and USNM 30850 (n = 6), July 1902 (no additional collection information available).
This species is known from only 3 specimens.
|Diagnosis||Diagnosis. Mabuya montserratae sp. nov. is characterized by (1) maximum SVL in males, 85.3 mm; (2) maximum SVL in females, 98.0 mm; (3) snout width, 2.80–3.33% SVL; (4) head length, 17.1–18.6% SVL; (5) head width, 12.3–13.2% SVL; (6) ear length, 1.49–1.55% SVL; (7) toe-IV length, 9.51–11.4% SVL; (8) prefrontals, two; (9) supraoculars, three; (10) supraciliaries, four (only three appear to be present in some fetuses, but they are in poor condition); (11) frontoparietals, two; (12) supralabial below the eye, five (63%), six (38%); (13) nuchal rows, one (88%), two (13%); (14) dorsals, 57–63; (15) ventrals, 64–71; (16) dorsals + ventrals, 123– 134; (17) midbody scale rows, 32–34; (18) finger-IV lamellae, 14–15; (19) toe-IV lamellae, 16–18; (20) finger-IV + toe-IV lamellae, 30–33; (21) supranasal contact, Y (25%), N (75%); (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. montserratae sp. nov. differs from all other species by having a shorter frontonasal (frontonasal length 16.5–16.8% HL versus 17.8–23.9% in those other species; Fig. 34). It differs from M. dominicana, M. grandisterrae sp. nov., M. guadeloupae sp. nov., and M. mabouya by having a lower supraciliary-2/supraciliary-3 length ratio (1.39–1.66 versus 1.67–2.40 in those other species; Fig. 36). It differs from M. dominicana and M. mabouya in having a wider supranasal (supranasal length/supranasal width 3.19–3.58 versus 3.61–6.57 in those other species; Fig. 35). It is separated from M. hispaniolae sp. nov. by having a larger ear (ear length 1.49–1.55% SVL versus 1.11–1.46% in M. hispaniolae sp. nov.). Additionally, M. montserratae sp. nov. tends to have more midbody scale rows than M. hispaniolae sp. nov.: 32 (four individuals) and 34 (four) versus 30 (six) and 32 (two). Also, 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. Although hard to quantify in old specimens, the ear of M. montserratae sp. nov. also differs in shape from other species in being dorsoventrally elongated, versus more rounded [HEDGES & CONN 2012].
|Comment||Distribution: Mabuya montserratae sp. nov. is the northernmost species in the Genus Mabuya, in the Lesser Antilles.|
Abundance: only known from its original description (Meiri et al. 2017).
