| Diagnosis | Diagnosis. Pseudogekko brevipes can be distinguished from congeners by the following combination of characters: (1) body size moderate (SVL 34.5–42.4 mm); (2) axilla–groin distance moderate (17.8–29.8 mm); (3) head length moderate (6.2–9.5 mm); (4) snout length long (3.8–4.4 mm); (5) Toe-IV scansors 15; (6) paravertebrals 211–218; (7) ventrals 96–117; (8) supralabials 13 or 14; (9) infralabials 14 or 15; (10) circumorbitals 33–35; (11) precloacal pores 12; (12) femoral pores absent; (13) conspicuous dorsolateral spotting present; (14) limb spotting absent; (15) tail banding absent; (16) body striping absent; (17) interorbital banding present (Tables 1, 2; Figs. 2, 3) (DAVIS et al. 2015). Comparisons. Characters distinguishing Pseudogekko brevipes from all other species of Pseudogekko are summarized in Tables 1–3. Pseudogekko brevipes most closely resembles the new species described below; however, it differs from this species by having a shorter snout–vent length in both males (39.0 mm vs. 41.1–52.5) and females (34.5–42.4 mm vs. 44.8–48.7), shorter eye–nares distance (3.0–3.4 mm vs. 3.5–4.5), a tendency towards having both a shorter snout length (3.8–4.4 mm vs. 4.3–5.8) and internares distance (1.2–1.6 mm vs. 1.5– 1.9), fewer supralabials (13 or 14 vs. 15–17), circumorbitals (33–35 vs. 35–38), paravertebrals (211–218 vs. 226– 240), ventrals (96–117 vs. 119–129), and precloacal pores (12 vs. 13–15; Fig. 3). Pseudogekko brevipes can be distinguished from P. chavacano by having a shorter snout–vent length (34.5– 42.4 mm vs. 54.7, 55.9), total length (72.0–87.5 mm vs. 95.8), midbody width (4.5–5.8 mm vs. 6.4, 6.7), head length (6.2–9.5 mm vs. 10.4), head width (5.6–6.5 mm vs. 7.8, 8.5), and snout length (3.8–4.4 vs. 5.8, 6.0), fewer Finger-III scansors (12 vs. 15, 16), Toe-IV scansors (15 vs. 17–20), supralabials (13, 14 vs. 15, 16), infralabials (14, 15 vs. 16, 17), circumorbitals (33–35 vs. 46), ventrals (96–117 vs. 122, 123), and precloacal pores (12 vs. 16), greater number of paravertebrals (211–218 vs. 195–197), absence (vs. presence) of limb spotting and tail banding, and presence (vs. absence) of interorbital banding; from P. compresicorpus by having a shorter snout–vent length (34.5–42.4 mm vs. 54.9–59.7), total length (72.0–87.5 mm vs. 105.9–117.3), head width (5.6–6.5 mm vs. 7.5– 10.1), and snout length (3.8–4.4 mm vs. 5.3–7.4), fewer Finger-III scansors (12 vs. 15–17), Toe-IV scansors (15 vs. 18 or 19), supralabials (13 or 14 vs. 16–20), circumorbitals (33–35 vs. 39–45), and ventrals (96–117 vs. 127–130), absence (vs. presence) of limb spotting, and presence (vs. absence) of interorbital banding; from P. ditoy by having a shorter snout–vent length (34.5–42.4 mm vs. 49.4–52.6), midbody width (4.5–5.8 mm vs. 6.3–7.3), head width (5.6–6.5 mm vs. 7.7–7.9), and snout length (3.8–4.4 mm vs. 5.4–5.7), fewer Finger-III scansors (12 vs. 14 or 15), Toe-IV scansors (15 vs. 16 or 17), supralabials (13 or 14 vs. 17–20), infralabials (14 or 15 vs. 16 or 17), circumorbitals (33–35 vs. 40–43), and precloacal pores (12 vs. 18), greater number of paravertebrals (211–218 vs. 180–185), presence (vs. absence) of dorsolateral spotting and interorbital banding; from P. pungkaypinit by having a shorter snout–vent length (34.5–42.4 mm vs. 66.6–76.8), axilla–groin distance (17.8–29.8 mm vs. 37.2–41.2), total length (72.0–87.5 mm vs. 125.3–141.2), midbody width (4.5–5.8 mm vs. 7.7–9.1), head length (6.2–9.5 mm vs. 11.4–13.6), head width (5.6–6.5 mm vs. 9.3–11.2), and snout length (3.8–4.4 mm vs. 6.7–7.5), fewer Finger-III scansors (12 vs. 15–17), Toe-IV scansors (15 vs. 17–21), supralabials (13 or 14 vs. 16–20), infralabials (14 or 15 vs. 17–19), circumorbitals (33–35 vs. 50–55), paravertebrals (211–218 vs. 265–280), ventrals (96–117 vs. 125– 155), and precloacal pores (12 vs. 17–20), presence (vs. absence) of dorsolateral spotting and interorbital banding, and absence (vs. presence) of body striping; from P. smaragdinus by having a shorter snout–vent length (34.5–42.4 mm vs. 50.2–64.3), total length (72.0–87.5 mm vs. 103.6–129.7), midbody width (4.5–5.8 mm vs. 6.2–10.4), head width (5.6–6.5 mm vs. 7.1–9.8), and snout length (3.8–4.4 mm vs. 4.9–6.5), fewer Finger-III scansors (12 vs. 15– 18), Toe-IV scansors (15 vs. 16–22), supralabials (13, 14 vs. 16–19), ventrals (96–117 vs. 124–130), and precloacal pores (12 vs. 32–41), absence (vs. presence) of femoral pores, conspicuous limb spotting, and tail banding, and presence (vs. absence) of interorbital banding (DAVIS et al. 2015). |
| Comment | The populations of P. brevipes from Negros and Siquijor have been redescribed as P. atiorum. Abundance: Rare. Pseudogekko brevipes is known only from a handful of specimens from the eastern Visayan islands of Bohol, Leyte, and Samar. Conservation: Vulnerable (DAVIS et al. 2015). Sympatry: possibly P. ditoy and P. pungkaypinit |
| Etymology | Named after Latin “brevis, -e” = short and “pes, pedis” = foot. |
