| Types | Holotype: MUSM (= MHNSM) 20116, adult male, collected by Cesar Aguilar on 21 April 1999. Original field number PE 1363. Paratype: SMF 81727, adult male |
| Diagnosis | Diagnosis (n=2): (1) Frontonasal length slightly smaller than frontal length; (2) nasoloreal suture present; (3) supraoculars three, anteriormost supraocular not fused with anteriormost superciliary, all supraoculars separated from ciliaries; (4) superciliary series complete, four scales; (5) supralabial-subocular fusion present; (6) postoculars two; (7) postparietals two; (8) supratympanic temporals two; (9) genials two, transverse sutures perpendicular with respect to midline of body; (10) dorsal scales rectangular, juxtaposed, striated; (11) transverse dorsal count (enlarged rows at midbody) at midbody 20; (12) longitudinal dorsal count 37; (13) longitudinal ventral count 20; (14) lateral scale rows at midbody three; (15) femoral pores in males nine, unknown in females; two scales between femoral pores; (16) subdigital scales on 4th finger 12, on 4th toe 16–17; (17) limbs not overlapping when adpressed against body in adults (separated by a distance equal to 1–2 dorsal scales); (18) anterior preanal plate scales paired; (19) hemipenis acapitate without a medial welt; apex with two large protrusions separated by the distal end of the sulcus spermaticus; flounces bearing calcified spines; about 20 flounces forming two chevrons on distal half of hemipenis while basal half is covered with 11 mostly uninterrupted transverse flounces; sulcate flounces about as wide as asulcate flounces; asulcate flounces becoming shorter distally, distal chevrons separated by a small expansion pleat; sulcus spermaticus single, bordered by well developed sulcal lips and flanked by a broad naked expansion pleat widened distally; sulcus spermaticus divided by a small protrusion distally; (20) dorsum dark grayish brown with a weakly defined dorsolateral pale stripe on neck and body; lateral ocelli absent; ventral surfaces dark bluish gray; (21) lower palpebral disc with vertical sections; (22) prefrontals absent. Proctoporus laudahnae can be distinguished from all congeners, except P. labionis and P. labioocularis, by having the fourth supralabial scale fused with a subocular scale (these scales usually distinct in all other species). Proctoporus laudahnae differs from P. labionis (condition for P. labionis in parentheses) by the presence a nasoloreal suture (absent) and a complete superciliary series (incomplete). The new species differs from P. labioocularis (condition for P. labioocularis in parentheses) by having striated dorsal scales (smooth), anteriormost supraocular not fused with anteriormost superciliary (fused), and 16–17 lamellae under the fourth toe (19–24). Proctoporus laudahnae can be distinguished further by the following (condition for P. laudahnae in parentheses): All Bolivian and Peruvian species, except P. ventrimaculatus and P. labioocularis: transparent lower palpebral disc an undivided oval (with vertical sections); from the latter two species by the fused anteriormost supraocular-anteriormost superciliary (not fused). All Ecuadorian species, except P. cashcaensis, P. hypostictus, and P. simoterus: supralabial-subocular fusion absent (present). Proctoporus cashcaensis: frontonasal much longer than frontal (equal or shorter), nasoloreal suture absent (present), superciliary series incomplete (complete). Proctoporus hypostictus: superciliary series usually incomplete (complete), genials three (two), longitudinal dorsal count in males 30–35 (37), femoral pores in males 4–6 (nine), limbs overlapping when adpressed against body (not overlapping). Proctoporus simoterus: dorsals smooth (striated), femoral pores in males 5–7 (nine), dorsum brown, distinctly bicolored (not bicolored). Species occurring north of Ecuador: all species, except P. columbianus: no band of granular scales along the sides of body between dorsal and ventral scales (granular scales present). Proctoporus columbianus: superciliary series incomplete (complete). Proctoporus laudahnae can be distinguished from all species currently placed in the genus Euspondylus by the absence of prefrontals (always present in the species of Euspondylus, except in E. spinalis in which this condition is variable). Proctoporus laudahnae further differs from E. rahmi, E. simonsii, and E. spinalis by having the transparent lower palpebral disc with vertical sections (palpebral disc an undivided oval in E. rahmi, E. simonsii, and E. spinalis). Proctoporus laudahnae differs from Opipeuter xestus by having several small subocular scales, the posterior one fused with a supralabial (a single large elongate subocular, not fused with a supralabial in O. xestus); the absence of prefrontals (present in O. xestus); a longitudinal ventral count of 20 (24–25 in O. xestus); and in hemipenis morphology (large spines at the base of the sulcus spermaticus in O. xestus versus no such spines present in P. laudahnae).
