Scutellation, meristic, and color pattern characters referenced in this study were identified and described in Tables 2-4.
Scutellation.--Specimens of the diploid parthenogenetic species A.
The qualitative scutellation characters examined in all specimens included sizes of the postantebrachial scales on the posterior aspect of each forearm and of the mesoptychial scales bordering the edge of the gular fold, anterior extent of the circumorbital scale series on both sides of the head, and number of parietal scales on the posterior aspect of the head (see Duellman and Zweifel, 1962).
Analyses of qualitative characters of scutellation, meristic variables (Table 1), color pattern (Figs.
sexlineatus (for example, in Alabama and Georgia) tend to exhibit much higher mean values for scutellation
than do the western populations of C.
and Meristic Characters--Specimens from South Padre Island and Tamaulipas possess characters that are diagnostic for A.
This is indicated by the wide range of character variability and clinial variation in color pattern and scutellation
throughout its geographic range as expected in relative recently differentiated and expanding populations (Vanzolini and Williams, 1970).
: There are 7/8 supralabials, 10/10 infralabials, 15 rows of smooth dorsal scales without reduction, 0 preoculars, 2 postoculars, and 1 + 3 temporals.
-- Study of geographic variation in features of scutellation
and pattern prompts recognition of a new subspecies of Bogertophis subocularis.
It differs from all Cuban species of Anolis in its green coloration with greenish gray bands on body, legs and tail, in having subtriangular mental scales as well as in other details of color and scutellation
. This new species is most closely related to A.
Dorsal scale formulae--15-15-11 (two specimens), 15-15-12 (two), and 15-15-13 (one)--and the head scutellation
of the Cuatro Cienegas material was typical for the subspecies.
