|Diagnosis||Diagnosis. A moderate-sized to moderately large species of Anolis that differs from all other Hispaniolan congeners except A. demissus and A. pecuarius and two species described below by the combination of having (1) predominantly green overall coloration in life (capable of rapid color change to brown); (2) a white subocular stripe that continues as a white streak onto lateral neck (3) hind legs relatively short (fourth toe of adpressed hind leg reaching to ear opening or only slightly beyond ear opening); (4) ventral scales at midbody usually faintly to distinctly keeled; (5) 39–47 subdigital lamellae on Phalanges II–IV of Toe IV of hind limbs; (6) male dewlap yellowish green or brown (after metachrosis) in life with longitudinal or oblique double rows of gorgetal scales; (7) ratio tail length / SVL >1.7, usually >2.0. Among the Anolis species treated in this contribution, A. coelestinus is most similar to A. demissus, A. pecuarius, and two species described below. Anolis coelestinus differs from A. demissus and A. pecuarius by (1) usually having a white subocular stripe and a white streak on lateral neck and shoulder (vs. such a pattern usually not present in A. demissus and A. pecuarius); a bluish green to yellowish green male dewlap in life (vs. yellowish brown, dark gray, or greenish gray in A. demissus and A. pecuarius); and (3) by usually having a pattern of white to pale green vertical bars or blotches on flanks (vs. usually lacking any pattern on flanks in A. demissus and A. pecuarius). Anolis coelestinus further differs from A. demissus by usually having 4 supracaudals per caudal segment, either throughout all discernable segments or having the reduction from 5 to 4 supracaudals per segment before the 5th segment (vs. 5 supracaudals per caudal segment throughout all discernable segments in A. demissus) and by usually having weakly to distinctly keeled ventral scales (vs. usually smooth in A. demissus). Anolis coelestinus differs from A. chlorocyanus, A. cyanostictus, and A. peynadoi by having (1) a yellowish green or brown (after metachrosis) in life dewlap with longitudinal or oblique double rows of gorgetal scales (vs. dewlap bicolored with a darker posterior portion and with regularly spaced more or less homogeneous gorgetal scales); (2) and a blue iris in life (vs. brown to reddish brown). Anolis coelestinus differs further from A. cyanostictus (1) by having a distinct white subocular stripe that continues as a white streak onto lateral neck (vs. no such stripe and streak in A. cyanostictus) and (2) by the lack of pale brown blotches above and anterior to shoulder as well as immediately posterior to eye (vs. such blotches present in A. cyanostictus). Anolis coelestinus differs from A. aliniger and A. singularis by (1) having a longer tail with a ratio tail length / SVL >1.7, usually >2.0 (vs. <1.7); (2) a distinct white subocular stripe that continues as a white streak onto lateral neck (vs. no such stripe and streak); (3) usually >38 subdigital lamellae on Phalanges II–IV of Toe IV of hind limbs; and (4) no conspicuously dark colored distal portion of tail in front of pale colored tail tip (vs. such a tail color pattern present, most obvious in life). For differences between A. coelestinus and the species described below, see the respective accounts of the new species [KÖHLER & HEDGES 2016: 18].|
|Comment||Synonymy: mostly after KÖHLER & HEDGES 2016: 18. Boulenger (1885: 44) listed A. coelestinus as a synonym of A. chlorocyanus, a view shared by Barbour (1914: 295). Barbour (1930: 119) resurrected A. coelestinus from the synonymy of A. chlorocyanus, stating that the latter has a ‘greater number of loreal rows’ and ‘smaller scales on the back, very fine scales on the dewlap, a different habit and coloration.’ Since that time this two-species concept and the respective assignments of names have remained unchanged (e.g. Mertens, 1939; Williams, 1965; Ramos & Powell, 2001).|
Similar species: Anolis coelestinus, A. viridius, A. chlorodius, A. demissus, A. pecuarius.
Subspecies: Anolis coelestinus demissus SCHWARTZ 1969 and Anolis coelestinus pecuarius SCHWARTZ 1969 have been elevated to full species status by KÖHLER & HEDGES 2016. Other populations of coelestinus have been described as new species, A. viridius and A. chlorodius.
