| Diagnosis | Diagnosis. A species of the genus Echinosaura with an extremely long snout, unpaired internasal, reduced numbers of supralabials and infralabials, enlarged caudal scales arranged in continuous transverse rings spanning the dorsal and lateral surfaces of the tail at the posterior margin of each autotomic segment; and elevated numbers of subdigital lamellae on the fourth toe. In contrast to other members of the genus, Echinosaura orcesi lacks continuous rows of slight to moderately enlarged scales in the paravertebral area of the body. (Fritts et al. 2002)
