DistributionGuadeloupe (La Désirade island, Terre de Bas, Îles de la Petite Terre)

Type locality: Anse d’Echelle, La Désirade, Guadeloupe  
TypesHolotype: KU 242045, an adult male, collected by Albert Schwartz and Richard Thomas at Anse d’Echelle, La Désirade, Guadeloupe, on 28 February 1963. Paratype (n = 1). Guadeloupe. KU 242046, an adult male, same locality and information as the holotype. 
DiagnosisDiagnosis. Mabuya desiradae sp. nov. is characterized by (1) maximum SVL in males, 98.1 mm; (2) maximum SVL in females, not available; (3) snout width, 2.56–2.86% SVL; (4) head length, 18.5–19.0% SVL; (5) head width, 13.6% SVL; (6) ear length, 1.45–1.47% SVL; (7) toe-IV length, 10.2–10.4% SVL; (8) prefrontals, two; (9) supraoculars, three; (10) supraciliaries, four; (11) frontoparietals, two; (12) supralabial below the eye, five (50%), six (50%); (13) nuchal rows, one; (14) dorsals, 62; (15) ventrals, 68–70; (16) dorsals + ventrals, 130–132; (17) midbody scale rows, 32–34; (18) finger-IV lamellae, 13–15; (19) toe-IV lamellae, 16–18; (20) finger-IV + toe- IV lamellae, 29–33; (21) supranasal contact, Y (50%), N (50%); (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, N; and (29) palms and soles, dark (Tables 3–5).
Within the Genus Mabuya, M. desiradae sp. nov. and the other three species inhabiting Guadeloupe and its islets (M. cochonae sp. nov., M. grandisterrae sp. nov., and M. guadeloupae sp. nov.), here placed in the M. guadeloupae sp. nov. species group, have a similarly-proportioned frontonasal scale that distinguishes them from other species in the genus (Fig. 34). Species in the M. guadeloupae sp. nov. species group have a longer frontonasal compared with M. montserratae sp. nov. (frontonasal length/head length 0.176–0.199 versus 0.165– 0.168) and a shorter frontonasal compared with other species in the genus (0.176–0.199 versus 0.205–0.239 in M. dominicana, M. hispaniolae sp. nov., and M. mabouya). In addition, M. desiradae sp. nov. differs from M. dominicana by having a shorter, wider supranasal scale (supranasal length/supranasal width 3.57–3.66 versus 4.57–6.57 in M. dominicana; Fig. 35), and in lacking a well-defined pale lateral stripe (present in 84% of M. dominicana). It is separated from M. hispaniolae sp. nov. by having a narrower snout (2.56–2.86% SVL versus 3.08–3.47% SVL) and in lacking well-defined lateral and pale dorsolateral stripes (such stripes are present and well-defined in M. hispaniolae sp. nov.). It is distinguished from M. mabouya by having more dorsals (62 versus 55–61) and a longer dark lateral stripe that extends two-thirds (versus one-third) of the body. It differs from M. montserratae sp. nov. by having a wider head (13.6% SVL versus 12.3–13.2% SVL) and a higher supraciliary-2/ supraciliary-3 length ratio (2.11–2.34 versus 1.39–1.66 in M. montserratae sp. nov.; Fig. 36).
Mabuya desiradae sp. nov. differs from M. cochonae sp. nov. by having shorter anterior loreal scale (1.70– 1.99% SVL versus 2.26–2.47% SVL; Fig. 37A), a shorter suture length between the upper secondary temporal and the parietal scale (1.85–2.01 versus 2.12–2.29% SVL; Fig. 37C), a larger ear (1.45–1.47% SVL versus 1.02–1.12% SVL), a larger separation of the prefrontal scales (1.74–1.75% SVL versus 0.89–1.16% SVL), longer dark lateral stripes and weakly defined pale dorsolateral stripes that extend two-thirds (versus one-third) of body, a dull silvery- gray (versus orange) venter in life, and a head that is more red in life. Mabuya desiradae sp. nov. differs from M. grandisterrae sp. nov. in having more dorsals (62 versus 54–61), more dorsals + ventrals (130–132 versus 116– 128), a higher supraciliary-2/supraciliary-3 length ratio (2.11–2.34 versus 1.67–1.79 in M. grandisterrae sp. nov.; Fig. 36), and a longer dark lateral stripe that extends two-thirds (versus one-third) of body. Mabuya desiradae sp. nov. differs from M. guadeloupae sp. nov. in having a longer anterior loreal (1.70–1.99% SVL versus 1.28–1.36% SVL; Fig. 37A), a longer interloreal suture (0.92–1.07% SVL versus 0.64–0.85% SVL; Fig. 37B), and a longer supralabial-7 (1.65–1.81% SVL versus 1.36–1.44% SVL; Fig. 37D), and in lacking dark dorsolateral stripes (present on nape in M. guadeloupae sp. nov.), pale lateral stripes (present in M. guadeloupae sp. nov.) and well- defined dorsolateral stripes (weakly-defined versus well-defined in M. guadeloupae sp. nov.) [HEDGES & CONN 2012].
