Type locality: Upa, bridle path to Yurumarca, District of Chiliquin, Province of Chachapoyas, Department of Amazonas, Peru (6°0’9.19” S; 77°49’21.08” W; ca. 3,020 m asl).  
Reproduction 
TypesHolotype. MUBI 11485, adult female (Figs. 2–4), collected by Juan C. Chaparro on 23 May 2012. Paratypes. Two specimens: A subadult male (MUBI 11473) and a subadult female (MUBI 11474) from near the type locality (5°59’40.27” S; 77°48’36.26” W; 3,250 m asl), collected by Juan C. Chaparro and Alexander Pari on 22 May 2012. 
DiagnosisDiagnosis: Petracola amazonensis is diagnosed based on the following combination of characters: (1) frontonasal longer than frontal; (2) nasoloreal suture absent; (3) two supraoculars; (4) one superciliary scale expanded on dorsal surface of head; (5) two postoculars; (6) palpebral disc transparent, entire or divided vertically in two; (7) four supralabials anterior to the posteroventral angle of the subocular; (8) 3–4 anterior infralabials; (9) four genials in contact; (10) three rows of pregulars; (11) dorsal body scales rectangular, smooth, juxtaposed; (12) 25–28 scales around midbody; (13) 31–32 transverse dorsal rows; (14) 18–19 transverse ventral rows; (15) 17–20 longitudinal dorsal rows; (16) 8–9 longitudinal ventral rows; (17) a continuous series of small lateral scales separate dorsals from ventral scales; (18) 2–4 posterior cloacal plate scales; (19) two anterior preanal plate scales; (20) four femoral pores per hind limb in males, two in females; (21) preanal pores absent; (22) 7–9 subdigital lamellae on finger IV; 11–14 subdigital lamellae on toe IV; (23) limbs not overlapping when adpressed against body; (24) pentadactyl, digits clawed; and (25) coloration of female in life: dorsum is brown with numerous dark spots distributed irregularly from tip of head to tail, flanks are similar to dorsum, the chin and throat are pale orange with large black spots, venter mostly orange, with black spots on anterior part of ventral scales forming longitudinal lines (Fig. 4); coloration of males in life is unknown; in preservative the dorsum is similar to coloration in life, and venter changes from orange to cream (Fig. 2). Petracola amazonensis can be distinguished from P. angustisoma and P. pajatensis by lacking a loreal scale (loreal scale present in P. angustisoma and P. pajatensis); from P. labioocularis by lacking precloacal pores and posterior subocular is not elongated downward (precloacal pores present and posterior subocular is elongated downward and separates supralabials in P. labioocularis); from P. waka by having two genials in contact, first superciliary scale, and venter is orange with black spots forming transverse bands (three genials in contact, four continuous superciliary scales, and venter is cream with some small, black spots in P. waka); from P. ventrimaculatus by having a maximum SVL in males of 43.0 mm, dorsum dark brown with some black spots not forming bands, and first superciliary only (maximum SVL in females 59.0 mm, dorsum light brown with continuous black dorsal bands, and 2–3 discontinuous superciliaries in P. ventrimaculatus).
