CommentHabitar: during day time under rocks and logs in cloud forests and humid cleared areas.

Diagnosis: (1) Frontonasal length equal to frontal length; (2) nasoloreal suture absent; (3) three supraoculars; (4) 3–4 superciliaries, first not expanded onto dorsal surface of head; (5) postoculars two; (6) palpebral disc made up of a single, undivided scale; (7) three supralabials anterior to the posteroventral angle of the subocular; (8) three pairs of genials in contact; (9) dorsal body scales quadrangular, slightly keeled; (10) transverse rows of dorsals 34–37 in males and 34–40 in females; (11) transverse ventral rows 22–24 in both sexes; (12) a continuous series of small lateral scales separating dorsals from ventrals; (13) posterior cloacal plate made up of six scales in both sexes; (14) anterior preanal plate scales paired; (15) femoral pores per hind limb in males 5–6 in males, absent in females; (16) preanal pores absent; (17) subdigital lamellae on toe IV 14–20; subdigital lamellae on toe V 6–13; (18) limbs not overlapping when adpressed against body in adults; (19) pentadactyl; digits clawed; (20) dorsum dark gray; lateral surface of head like dorsal surface, lip irregularly barred with cream coloring; ventral surface of head cream with clumps of black stippling on each scale; pregular region like head but with fainter stippling.
Specimens of Proctoporus iridescens show the presence of an undivided palpebral disc, which identifies them as members of the genus Proctoporus, as opposed to Riama and Petracola (Doan and Castoe, 2005; Uzzell, 1970). Proctoporus iridescens can be distinguished from its congeners by having three supralabials anterior to the posteroventral angle of the subocular (four in all other species of Proctoporus) and three pairs of genials in contact (two in all other species of Proctopo- rus). It can also be distinguished from P. pachyurus by having three supraoculars not fused with superciliaries (four supraoculars in P. pachyurus, first fused with first superciliary), and 34–40 transverse dorsal scale rows (47–60 in P. pachyurus); from P. sucullucu by having limbs not over- lapping when adpressed against body, first supraocular not fused with first superciliary (fused in P. sucullucu), and by the lack of loreal scale (present in P. sucullucu); from P. bolivianus by having frontonasal subequal to frontals and first supraocular not fused with first superciliary; from P. unsaacae and P. guentheri by the absence of a series of lateral ocelli; from P. carabaya by having first supraocular not fused with first superciliary and the lack of loreal scale; from P. kiziriani by the lack of loreal scale (present in P. kiziriani) and by the absence of dorsal stripes; from P. lacertus by having three supralabials anterior to the posteroventral angle of the subocular (four in P. lac- ertus); from P. xestus by the lack of prefrontal scales (present in P. xestus) and having keeled dorsal scales (smooth in P. xestus); and from P. chasqui by the lack of prefrontal scales. 
EtymologyThe specific epithet comes from Greek iris (“rainbow”), in allusion to the pretty iridescent reflections of the scales of this species.
