| Diagnosis | Diagnosis: This species differs from other members of the G. brachycephalus complex by having high numbers of subcaudals in females and in lacking sexual dimorphism in ventral counts (Table 4). It is characterized by having the following combination of features: (1) 137–138.5 ± 0.9–140 ventrals in males, 138 in the female; 44–47.0 ± 2.4–50 subcaudals in males, 43 in the female; 183–185.5 ± 1.9–188 total segmentals in males, 181 in the female; (2) uniform black dorsum and upper surface of tail or with the light blotched/banded pattern on posterior two-thirds of body and light markings on upper surface of tail (light markings probably red in life); (3) hemipenes simple, capitulum moderately long but slender, about 2.5 times as long as the short truncus on the asulcate side (Myers, 2003). |
