DistributionIndonesia (Moluccas, Halmahera (fide SMITH 1937), Morotai)

Type locality: “Halmaheira, im Norden, Westen und Osten die gemeinste Eidechsenart, namentlich auf Waldboden”  
TypesLectotype: SMF 15340 (= 6292, 4a in Mertens, 1922). 
DiagnosisDESCRIPTION. SVL of 10 mature adults 51.0-59.2 mm; snout tapering, strongly depressed, round pointed, its length 41-44% of HL and 68-77% of HB; HB 56-63% of HL and 15-18% of SVL; eye 53-62% of snout length and 38-43% of HB; rostral straight edged posteriorly; supranasals long, narrow, in contact with the anterior loreal; prefrontals separate or in contact; interparietal rather small or fused with frontoparietals; one pair of nuchals; anterior loreal much longer than high and nearly as long as posterior loreal; seven upper labials; sixth enlarged and below eye; six or seven lower labials; dorsal scales smooth; midbody scale rows 28-36, rarely more than 34 (x̅ = 31.286; SD = 1.496; n = 7); dorsal scale rows 54-60 (x̅ = 57.143; SD = 1.864; n = 7); length of extended hindlimb 106-118% of axilla-groin distance and 47-54% of SVL; rounded lamellae under fourth toe 41-48 (x̅= 43.0; SD = 1.915; n = 7); under first toe 9-13 (Brown 1991).

Comparisons. Emoia sorex differs from other species of the cyanogaster group primarily in the much less thinned and less numerous subdigital lamellae (Table 6). (Brown 1991) 
CommentSynonymy: Bauer (1994) proposed to suppress the name Euprepes samoensis moluccensis in favor of Emoia sorex, since the former has not been used since 1864 and thereby threatens nomenclatural stability.
