|Common Names||E: Digul Emo Skink|
|Synonym||Emoia digul BROWN 1991|
|Distribution||Indonesia (Irian Jaya)|
Type locality: about 1250 m elevation in the Sibil drainage, tributary to the Digul River, south side of the central mountain range in eastern Irian Jaya
|Types||Holotype: RMNH RENA 21220 + 21211, paratypes: RMNH|
|Diagnosis||DIAGNOSIS: Distinguished from other species in E. pallidiceps complex by following combination of characters: midbody scale rows 32-37; dorsal scale rows 53-60 (rarely more than 56); fourth toe lamellae 30-35; SVL at maturity 43-57 mm; lateral surfaces dark brown, marked by irregular row of scattered white scales or clusters of scales on flanks at level of limbs and few white scales or cluster of such scales on side of neck (Brown 1991: 30).|
DESCRIPTION. SVL 43.2-55.1 mm for nine mature males and 49.5-56.8 mm for nine females; snout tapered, bluntly rounded, its length 46-52% of HB and 32-36% of HL; HB 65-71% of HL and 15-1 7% of SVL; eye 73-86% of snout length and 3641% of HB; rostral forming long, relatively straight suture with frontonasal; supranasals triangular; prefrontals narrowly to rather widely separated; usually seven supraciliaries; one pair of nuchals; anterior loreal shorter and higher than posterior, in contact with first and second or only second upper labial; six or seven upper labials, fifth (rarely sixth) enlarged and below eye; six or seven lower labials; dorsal scales smooth; midbody scale rows 32-37 (x̅ = 33.909; SD = 1.477; n = 22); dorsal scale rows 53-60 (x̅ = 55.059; SD = 2.904; n = 17); length oT extended hindlimb 95-107% of axilla-groin distance and 36-41% of SVL; rounded lamellae under fourth toe 30-35 (x̅ = 32.05; SD = 1.468; n = 20); under first toe 8-11 (Brown 1991: 30).
COLOR (in preservative). Dorsal ground color light to medium brown with scattered, dark brown spots, smaller than individual scales; bordered by pale dorsolateral line at least anteriorly; lateral surfaces (six to eight scale rows) dark brown or ventral part somewhat mottled brown and grayish; flanks at level of limbs usually marked by row of scattered pale scales; usually two or three whitish scales or dashes between ear and forelimb; labials are dark barred; usually some dark brown marks on parietals and supraoculars; venter slate-gray to grayish ivory (Brown 1991: 30).
COMPARISONS. Emoia digul is similar in color pattern to some populations of E. pallidiceps, but the pale lateral line is always broken into spots or segments. The head is broader relative to its length (see ratios in descriptions). Also, E. digul differs from adjacent populations of E. pallidiceps in southern Papua New Guinea in the significantly greater means of dorsal scale rows (t = 3.071, df = 6, P = 0.003) (Brown 1991: 30).
