|Diagnosis||Definition. A bisexual taxon of geckos (Gekko- ninae) with large adults (♀♀ 61–73 mm, ♂♂ 60–70 mm SVL) with keeled subcaudals, variable-sized postmental scales (2–19, usually ≥8), no or slight postmental-infralabial (PmLab = 0–1) contact, moderate number of dorsal tubercle rows (17–20) and moderate number of tubercles (27–34, usually ≥28) in parasagit- tal row (TubRow), tubercles on dorsal surface of thigh and crus, and precloacal pores (9, 8–11) in males, females lack pores (0). Diagnostic summary in Table 8.|
Coloration in life not reported.
Variation. Females and males display slight metric differences (adult ♀♀ 67.3, 61.5–73.1 mm; adult ♂♂ 66.8, 59.5– 69.5 mm SVL), although sharing similar proportions (total adult sample): TrunkL/SVL 38.6%, 35%–45%; HeadL/SVL 27.8%, 27%–29%; HeadW/SVL 18.2%, 15%–20%; HeadW/HeadL 65.6%, 56%–71%; EyeD/SVL 6.7%, 6%–8%; EyeD/HeadL 24.1%, 21%–29%; NarEye/HeadL 33.2%, 30%–43%; Inter- orb/HeadL 25.2%, 22%–30%; SnW/HeadL 14.5%, 13%–16%.
Typical head scale pattern of small, granular scales except for those bordering nares and mouth. Snout with large rostral scale bearing middorsal cleft posteriorly; supranasals moderate sized, usually in contact on midline or separated by small granu- lar scale (internasal); large supralabials (4, 3–4) and infralabi- als (3.5, 3–4) in front of anterior edge of orbit, first supra- and infralabial largest of respective series. Chin with large trapezoi- dal mental and usually moderate-sized postmentals (Postm = 10, 2–19) and usually no genial scale between postmental and first supralabial (0, 0–1 PmLab); dorsally, trunk with 19, 17–20 (DorsTub) enlarged tubercles transversely on dorsum and with 30, 27–34 tubercles (TubRow) longitudinally along trunk; 10, 8–10 tubercle rows transversely between hindlimbs (TubHip). Uniform covering of small tuberculate-like scale on dorsal half of forelimb and enlarged tubercles on crus and femur (TubHindl = 2). Tail with small uniform scales dorsally and laterally, ventrally typically with uniform, small keeled scales (Subcaud = 0, 0–1). Usually, single cloacal spurs (1, 1–2 CloacS) on each side. Ventral scales from chin to vent small, granular, somewhat larger on chest and abdomen. Precloacal pores, males 8–11, females 0. Forefoot with narrow digits, their lengths usually 3≈4>2>5>1; 18, 16–19 lamellae beneath fourth digit (4FingLm), 5, 4–7 scale rows on palm; hindfoot with narrow digits, their lengths 4≈3>2≈5>1; 22, 20–23 lamellae beneath fourth toe (4ToeLm).
Coloration in life, dorsal and lateral background variable light to medium brown with distinct to diffuse dark transverse bars middorsally continuous or separated, usually dark nape bar and always mid-cervical bar, 5 bars from shoulder to trunk; dark-brown sacral and first caudal bars always evident; top of head unicolor to scattered dark marks. Dorsally, limbs usually dark brown mottled, posterior thighs of most individuals with pair of dark horizontal stripes enclosing near-white stripe. In alcohol, background tan to medium brown dorsally and later- ally. Top of head with medial darker-brown figure from interor- bital onto snout, supralabials large, brown with white to cream posterior margin, infralabials cream to dusky white. Nearly uni- form tan dorsally from crown onto base of tail. Venter uniform light tan from chin onto tail.
