| Distribution | Ecuador (Morona-Santiago), elevation 2195–2286 m Type locality: Pailas, a tambo on the trail between Sevilla de Oro and Méndez, on the eastern or notheastern facing slope, Morona-Santiago, Ecuador |
| Reproduction | oviparous |
| Types | Holotype: USNM 229646, adult male; paratypes: USNM. Other material: USNM, AMNH |
| Diagnosis | Diagnosis: -(1) Frontonasal length equal to distinctly longer than frontal; (2) nasoloreal suture absent, incomplete, or complete; (3) supraoculars four, second and third in contact with ciliaries; (4) superciliary series incomplete, one anteriorly, one posteriorly; (5) supralabial-subocular fusion absent; (6) postoculars two; (7) post-parietals two or three; (8) supratympanic temporals three; (9) genials two, transverse sutures not perpendicular with respect to midline of body; (10) dorsals rectangular, juxtaposed, striated/keeled; (11) longitudinal dorsal scale rows in males 25-27, in females 22-27; (12) transverse dorsal scale rows in males 36-41, in females 36-40; (13) transverse ventral scale rows in males 21-24, in females 21-23; (14) lateral scale rows two or three; (15) femoral pores in males 9-11, in females zero; scales between femoral pores in males 0-2; (16) subdigital scales on Toe I four or five; (17) limbs not overlapping when adpressed in adults; (18) anterior cloacal plate scales 0-2; (19) hemipenial morphology unknown; (20) dorsum dark brown, with scattered darker brown spots especially laterally; dorsolateral line present or absent; venter unicolored dark brown or with distinct yellow markings ventrolaterally on body and tail. Proctoporus stigmatoral can be distinguished from all congeners by the presence of a mostly dark brown background with cream or yellow ventrolateral spots on the body and tail. This species can be further distinguished as follows (condition for P. stigmatoral in parentheses): All Ecuadorian congeners except P. cashcaensis, P. orcesi, P. petrorum, P. raneyi, P. vietus: femoral pores in females one or more (zero; one specimen of P. anatoloros with pore count of 0/1). P. cashcaensis: supratympanic temporals usually two (three); scales between femoral pores in males 3-6 (0-2). P. orcesi: usually complete (incomplete) superciliary series; longitudinal dorsal scale rows in males 13-23 (25-27). P. petrorum and P. raneyi (usually): superciliaries one (two). P. petrorum: frontonasal shorter than (longer than or equal to) frontal; femoral pores in males four (9-11); scales between femoral pores in males eight (0-2). P. raneyi: supraoculars two or three (four). P. vietus: transverse dorsal scale rows 29-32 (36-41); most scales rugose (striated/keeled); superciliaries series complete (incomplete); genials three (two). P. luctuosus group and P. striatus: superciliary series complete (incomplete), limbs overlapping (not overlapping) when adpressed against the body. P. columbianus and P. ventrimaculatus: dorsal scales smooth (striated/keeled). P. striatus: femoral pores in males 4-9 (9-11).

| Etymology | The specific epithet, stigmatoral, is an noun in apposition formed from the Greek noun stigma, -tos, meaning spot, and the Latin noun toral, -alis, meaning valance. The name refers to the ventrolaterally positioned spots characteristic of this species. |
