DiagnosisDiagnosis. Spondylurus monitae sp. nov. is characterized by (1) maximum SVL in males, 90.3 mm; (2) maximum SVL in females, 94.5 mm; (3) snout width, 2.42–3.16% SVL; (4) head length, 16.2–17.8% SVL; (5) head width, 11.5–13.8% SVL; (6) ear length, 1.35–1.59% SVL; (7) toe-IV length, 8.34–10.7% SVL; (8) prefrontals, two; (9) supraoculars, three (43%), four (57%); (10) supraciliaries, three (29%), four (43%), five (29%); (11) frontoparietals, two; (12) supralabial below the eye, five; (13) nuchal rows, two; (14) dorsals, 62–64; (15) ventrals, 64–69; (16) dorsals + ventrals, 126–132; (17) midbody scale rows, 32–34; (18) finger-IV lamellae, 12–15; (19) toe-IV lamellae, 16–17; (20) finger-IV + toe-IV lamellae, 29–32; (21) supranasal contact, N; (22) prefrontal contact, N; (23) supraocular-1/frontal contact, Y (86%), N (14%); (24) parietal contact, Y; (25) pale middorsal stripe, Y; (26) dark dorsolateral stripe, Y; (27) dark lateral stripe, Y; (28) pale lateral stripe, Y; and (29) palms and soles, pale (Tables 3–5).

Within the Genus Spondylurus, S. monitae sp. nov. is separated from all other species by having concave (versus parallel) dark dorsolateral stripes on the parietal scales, forming a constriction on the top of the head (Fig. 73A). It differs from S. caicosae sp. nov., S. fulgidus, S. haitiae sp. nov., S. magnacruzae sp. nov., S. martinae sp. nov., S. nitidus, S. powelli sp. nov., S. spilonotus, and S. turksae sp. nov. by having a higher dark dorsolateral stripe width/middorsal stripe width ratio (0.874–1.27 versus 0.115–0.805 in those other species). It differs from S. anegadae sp. nov. and S. semitaeniatus by having a lower dark dorsolateral stripe width/middorsal stripe width ratio (0.874–1.27 versus 1.35–3.79 in those other species). It differs from S. lineolatus and S. turksae sp. nov. by having more midbody scale rows (32–34 versus 26–30). From S. anegadae sp. nov., it differs by lacking supranasal contact (versus contact in S. anegadae sp. nov.). It differs from S. lineolatus by having a longer head (head length 16.2–17.8% SVL versus 12.9–14.4% in S. lineolatus). It is distinguished from S. macleani by having lateral dark and pale stripes. From S. monae sp. nov., it differs by having a higher rostral scale (Fig. 61). Spondylurus monitae sp. nov. further differs from S. monae sp. nov. in being larger: four of the six adult specimens are larger (88.5–94.5 mm SVL) than all of the 35 specimens of S. monae sp. nov. examined (87.0 mm SVL, maximum).
Spondylurus monitae sp. nov. also differs from other species in slightly overlapping characters. From S. culebrae sp. nov., S. magnacruzae sp. nov., S. monae sp. nov., and S. spilonotus, it is distinguished by having fewer supralabials (supralabial five below the eye versus supralabial six or seven below the eye in 84–91% of specimens belonging to those other species). From S. nitidus, it differs by having a higher frequency of supraocular-1/frontal contact (contact in 86% of specimens versus no contact in 93% of specimens belonging to S. nitidus). It is separated from S. semitaeniatus and S. sloanii by lacking supranasal contact (versus contact in 95– 96% of specimens belonging to those other species) [HEDGES & CONN 2012]. 
CommentSynonymy: Pinto-Sánchez et al. 2015 synonymized culebrae, macleani, and monitae with Spondylurus sloani.

Abundance: only known from (Meiri et al. 2017). 
EtymologyThe species name (monitae) is a feminine genitive singular noun referring to the distribution of the species on the island of Monito (it is feminine despite the masculine diminutive Spanish island name).
