Echinosaura centralis possesses the following characteristics: (1) snout pointed; (2) internasal divided longitudinally (rarely single); (3) frontonasals paired; (4) frontal single and long (it extends up to the middle of the eyes); (5) frontoparietals paired; (6) supraoculars two or three, large; (7) supralabials 4–6 (usually five); (8) infralabials 3–5 (usually four); (9) postmental single; (10) large chin shields in one pair; (11) two paravertebral ridges, separated from each other by usually five or more small, irregular scales; (12) spine-like scales forming oblique lines on lateral surface of body; (13) ventral scales squared, usually keeled; (14) subdigital lamellae on the fourth finger 12–18; (15) subdigital lamellae on the fourth toe 20–27; (16) femoral pores per hind limb in males 4–9; (17) dorsal surface of tail with two parallel ridges, formed by a series of increasing in size scales from the anterior margin of each caudal segment; lateral surface of tail with more-developed scales forming longitudinal ridges (coded as ‘= pattern’); (18) subcaudals per caudal segment three (when tail is not regenerated); (19) dorsum brown or dark brown, relatively uniform, sometimes with yellowish marks and/or two spots more or less distinguishable at the base of tail; ventral surface of head and neck mainly light brown, except on the anterior part where there is a darker ground colour with some transverse cream blotches, extending to labial scales; ventral surface of body (including limbs) mainly light brown spotted with dark brown or cream, while that of tail almost completely dark. Colouration in preservative is darker in some specimens [VÁSQUEZ-RESTREPO et al. 2019]. |
| Comment | Synonymy: Uzzell 1965 synonymized E. centralis with E. h. palmeri, but VÁSQUEZ-RESTREPO et al. 2019 revalidated it. |
| Etymology | Named after Latin centralis, central; centrally located; in middle, center. [“...As the seven specimens from Muzo... and the one from Robledo... are all very much alike... and occupy a different area, I consider them to represent an undescribed form, which I shall call Echinosaura centralis sp. nov...”]. |
