Deiroptyx equestris Species Group
Diagnosis. — Support for this group is provided by 120 apomorphies including 23 morphological and 97 molecular ones. There are 15 unequivocal morphological apomorphies: size of interparietal scale decreased (7: m to t); base of tail round (15: z to a); increased mean number of ventral scales in 5% of snout-to-vent length (20: n to p); decreased mean number of scales across snout (29: l to d); modal number of supraciliary scales zero (38: 1 to 0); external naris separated from rostral by two scales, not in contact with supralabial (modal condition) (39: 0 to 3); scales in supraocular disk about equal in size (41: 0 to 4); modal number of lumbar vertebrae three (52: 1 to 0); modal number of caudal vertebrae anterior to first autotomic vertebra ten (53: 4 to 1); dorsal surface of skull rugose with bony tubercles (56: a to z); parietal casque present (59: a to z); anterior edge of nasal does not reach naris (66: a to z); lateral edge of vomer with posteriorly directed lateral processes (72: a to z); anterior-most aspect of posterior border of dentary is anterior to mandibular fossa (84: z to a); and large splenial present (85: 1 to 0). There are 79 unequivocal molecular apomorphies (see Appendix II).
Definition. — Members of this species group are giant anoles (maximum adult male snout-to-vent lengths between 140 to 191 mm, and maximum in adult females 121 to 176 mm) sharing the following combination of features: 1) rugose cephalic casque formed of hard pustulate tubercles; 2) dewlap large in both sexes, its base extending beyond axilla onto venter; 4) splenial present; 5) dorsal scales, small, round, and smooth; 6) ventral scales small, round, and smooth, smaller than dorsals; 7) Type I karyotype: 2N = 36 (24M, 24m), N.F. = 48; no sexual heteromorphism.
Content. — This species group contains six species and a total of 26 species and subspecies (see Appendix III).
Distribution. — Cuba and its satellite islands ( Fig. 14).
Introduction. — Deiroptyx equestris to Grand Cayman Island , south Florida and Hawaii .
