|Diagnosis||Diagnosis: Echinosaura brachycephala possesses the following characteristics: (1) snout relatively short and rounded; (2) internasal single; (3) frontonasals paired [rarely with 1–4 small irregular scales between the frontonasals and the frontal (‘prefrontals’)]; (4) frontal single (rarely divided); (5) frontoparietals paired; (6) supraoculars three (third supraocular smaller than first and second); (7) supralabials 3–5 (usually four); (8) infralabials three; (9) postmental reduced or absent; (10) chin shields not differentiated; (11) two paravertebral rows of tubercles or spine-like scales, slightly undulating, separated from each other by 4–6 small, irregular scales; (12) tubercular scales forming oblique lines on lateral surface of body; (13) ventral scales keeled, squared (or are rounded squares); (14) subdigital lamellae on the fourth finger 16–23; (15) subdigital lamellae on the fourth toe 23–32; (16) femoral pores per hind limb in males 7–9, in females 1–2; (17) dorsal and lateral surface of tail with small tubercles scattered along each caudal segment (coded as ‘< pattern’); (18) subcaudals per caudal segment four (when tail is not regenerated); (19) dorsum brown or dark brown, relatively uniform, with some clear spots more or less visible; ventral surface of head and neck light brown with several scales bearing white spots, except on the edges near the mouth where there is a darker ground colour with some transverse cream blotches which extend to labial scales; ventral surface of body (including limbs and tail) mainly light brown spotted with dark brown and cream.|
Combination of these characteristics distinguishes Echinosaura brachycephala from its congeners. In addition, the distinctiveness of E. brachycephala and its sister-species, E. horrida, is further corroborated by uncorrected pairwise distances of 18.8% in ND4 and 6.5% in 16S (Table 1, Fig. 2 in VÁSQUEZ-RESTREPO et al. 2019).
