| Diagnosis | Diagnosis:-(1) Frontonasal distinctly longer to distinctly shorter than frontal; (2) nasoloreal suture usually absent; (3) supraoculars four, usually none in contact with ciliaries; (4) superciliary series usually complete, 4-6; (5) supralabial-subocular fusion absent; (6) postoculars 2-4, usually three; (7) postparietals two or three, usually three; (8) supratympanic temporals 2-4, usually two or three; (9) genials two or three, usually three, transverse sutures nearly perpendicular with respect to midline of body; (10) dorsals rectangular, juxtaposed, with low rounded keel; (11) longitudinal dorsal scale rows 13-23; (12) transverse dorsal scale rows in males 32-43, in females 33-42; (13) transverse ventral scale rows 19-23; (14) lateral scale rows 0-8, usually 4-8; (15) femoral pores in males 10-14, absent in females; scales between femoral pores in males 0-2; (16) subdigital scales on Toe I 4-6; (17) limbs not overlapping when adpressed against body in adults; (18) anterior cloacal plate scales paired; (19) hemipenis small, capitate; flounces bearing spines, forming two chevrons; distal one-third of sulcus spermaticus forked; (20) dorsum brown with distinct pale dorsolateral stripe above forelimbs and hind limbs. Proctoporus orcesi is unique among Proctoporus in that the hemipenis is relatively small and the distal one-third of the sulcus spermaticus is divided. It can be further distinguished from its congeners by the following characters (condition for P. orcesi in parentheses): P. anatoloros (usually), P. balneator, P. colomaromani, P. columbianus, P. hypostictus, P. labionis, P. luctuosus group, P. meleagris, P. oculatus, P. simoterus, P. unicolor, and P. ventrimaculatus: femoral pores in females present (absent). P. cashcaensis, P. petrorum, P. raneyi, P. stigmatoral, P. unicolor, and P. vespertinus: superciliary series incomplete (complete). P. vietus: dorsal scales rugose (striated/keeled). P. columbianus, P. meleagris, P. simoterus, and P. ventrimaculatus: dorsal scales smooth (striated/keeled). Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 32 characters) are available for collaborators and contributors. Please contact us for details. |
