|Diagnosis||Diagnosis. Spondylurus turksae sp. nov. is characterized by (1) maximum SVL in males, 79.3 mm; (2) maximum SVL in females, 79.1 mm; (3) snout width, 2.42–3.69% SVL; (4) head length, 15.2–16.5% SVL; (5) head width, 12.0–13.0% SVL; (6) ear length, 1.30–1.81% SVL; (7) toe-IV length, 7.05–8.90% SVL; (8) prefrontals, two; (9) supraoculars, four; (10) supraciliaries, four (86%), five (14%); (11) frontoparietals, two; (12) supralabial below the eye, five (67%), six (33%); (13) nuchal rows, two (86%), three (14%); (14) dorsals, 59–63; (15) ventrals, 59–63; (16) dorsals + ventrals, 119–126; (17) midbody scale rows, 30; (18) finger-IV lamellae, 12– 15; (19) toe-IV lamellae, 15–17; (20) finger-IV + toe-IV lamellae, 28–30; (21) supranasal contact, N; (22) prefrontal contact, N; (23) supraocular-1/frontal contact, Y (14%), N (86%); (24) parietal contact, Y; (25) pale middorsal stripe, Y; (26) dark dorsolateral stripe, Y; (27) dark lateral stripe, Y; (28) pale lateral stripe, N (or weak); and (29) palms and soles, pale (Tables 3–5).|
Within the Genus Spondylurus, S. turksae sp. nov. differs from S. anegadae sp. nov., S. culebrae sp. nov., S. haitiae sp. nov., S. monae sp. nov., S. monitae sp. nov., S. semitaeniatus, and S. sloanii by having a wider middorsal stripe (3.51–4.68% SVL versus 0.953–3.32% SVL in those other species) and a lower dark dorsolateral stripe width/middorsal stripe width ratio (0.187–0.622 versus 0.64–3.79 in those other species; Fig. 79). It differs from S. macleani, S. magnacruzae sp. nov., S. martinae sp. nov., S. monitae sp. nov., S. powelli sp. nov., S. sloanii, and S. spilonotus in having fewer midbody scale rows (30 versus 32–34). It differs from S. fulgidus, S. haitiae sp. nov., and S. nitidus in having a shorter toe (toe-IV length 7.05–8.90% SVL versus 9.01–12.9% SVL). It differs from S. haitiae sp. nov., S. martinae sp. nov., and S. monitae sp. nov. in having fewer ventral scales (59–63 versus 64–72). It differs from S. anegadae sp. nov. by lacking supranasal contact (versus supranasals in contact in S. anegadae sp. nov.). It differs from S. caicosae sp. nov. in being larger (three of seven S. turksae sp. nov. > 77.7 mm SVL versus all 99 specimens of S. caicosae sp. nov. < 77.6 mm SVL) and in having a higher ear (ear height 1.57–1.87% SVL versus 0.73–1.52% SVL), a wider pale dorsolateral stripe (1.98–2.33% SVL versus 1.02–1.73% SVL), and a dark lateral stripe that is irregular and extends to hindlimbs (versus straight-edged and extends only half-way to hindlimbs). It differs from S. fulgidus in having more dorsal scales (59–63 versus 52–58). It differs from S. haitiae sp. nov. in having a longer ear (ear length 1.30–1.81% SVL versus 1.19% SVL) and fewer dorsals + ventrals (119–126 versus 129–131). It differs from S. lineolatus in having a wider snout (snout width 2.42–3.69% SVL versus 1.97–2.34% SVL), a longer head (head length 15.2–16.5% SVL versus 12.9–14.4% SVL), a wider head (head width 12.0–13.0% SVL versus 9.58–11.6% SVL), more finger-IV lamellae (12–15 versus 8–11), more finger-IV + toe-IV lamellae (28–30 versus 21–26) and fewer dark stripes (four versus 10). It differs from S. nitidus in having a shorter head (head length 15.2–16.5% SVL versus 16.6–20.7% SVL) [HEDGES & CONN 2012].
