FIGURE 25. Distribution and frequency map for Leptophis nigromarginatus based upon the material examined. Red (head pattern 1) and green (head pattern 2) colors refer to two different patterns related to the prominence of black borders and spots on the supraocular and parietal scales (see text for details). Circle sizes are proportional to the number of individuals with each color pattern per locality.
