Diagnosis | Diagnosis: A moderate sized, 20-scale-row species of Typhlops, having moderate middorsal scale counts (284–328) and a low frequency of posterior reduction. Typhlops hectus differs from the other 20-row species with ~300 middorsal scales in its clavate rostral shape in which the rostral broadens posteriorly, becoming broadly rounded at the tip (Fig. 3A). The anterior projection of the preocular has a relatively small angle and sharp apex. The posterior nasal-preocular suture curves gradually ventrad. The suture between the preocular and the 3rd infralabial is relatively short. The edges of the posterior nasals flanking the rostral tend to bowed out. The pigmentation is variable but most populations are relatively lightly pigmented, ranging from medium to pale brown or tan, often with irregularities or mottling and a pale snout. The hemipenes are trumpet-shaped. |
