Anolis angusticeps
Species Group
Diagnosis.
—
Support for this group is provided by 56 apomorphies including zero morphological and 56 molecular ones. Twenty of the latter are unequivocal (see Appendix II).
Definition.
—
Lizards of this species group are small anoles (maximum snout-to-vent length in adult males
41 to 53 mm
and
40 to 47 mm
in adult females) sharing the following combination of characters: 1) no transparent scales in lower eyelid; 2) interparietal scale small, about same size as adjacent scales; 3) head elongate, length much longer than width; 4) arms and legs short; 5) tail short, about 2.0 times snout-to-vent length; 6) dewlap present or absent in females; 7) five or six lumbar vertebrae; 8) seven aseptate caudal vertebrae anterior to first autotomic vertebra.
Content.
—
This species group contains seven species and a total of nine species and subspecies (see Appendix III).
Distribution.
—
Cuba
, its satellite islands, Hispaniola, and
the Bahamas
(
Fig. 21
).
Remarks.
—
A pair of sister species,
Anolis garridoi
and
A. guazuma
, form a basal branch to the
loysianus
group in the molecular tree and have a similar relationship to the
angusticeps
group in the combined tree.
Rodriguez-Schettino (1999)
groups these taxa with other narrow-headed forms in her
carolinensis
species group. Members of the
loysianus
species group, in contrast, have shorter and broader heads. One solution to the incongruence between the trees would be to place the two species at issue into a separate species group but we are influenced by Rodriguez-Schettino’s treatment and include them in the
angusticeps
group pending further study.
