TypesHolotype: FMNH 13715, collected by Karl P. Schmidt in 1929. 
DiagnosisDefinition and diagnosis. A small Emoia with well-developed limbs; snout moderately tapering and round-pointed; number of scale-rows around the middle of the body 28-32; number of lamellae beneath the fourth toe 74-88; number of scale-rows from the parietals to the base of the tail 52-59; interparietals consistently absent; color pattern with a mid-dorsal light stripe which is two plus two half scale-rows in breadth at the nape but basically two-plus along the back. Margins are uneven, however, and in the two rows of dark scales separating the mid-dorsal from the dorso-lateral light stripes, at intervals of one to four scales, are light blotches covering a part or all of a scale. The light stripes are greenish bronze in the head region, greenish blue on the body, and merge with the blue of the tail posteriorly. Differs from E.cyanura from the same locality in the distinctive color pattern and the slightly greater number of rows of scales around the middle of the body; from E. schmidti, to which it appears to be most closely related, in the generally smaller size, lower number of scales around the middle of the body, and color pattern (Brown 1954).

Description of type. Body moderately slender; snout moderately tapering, rounded; supranasals long and narrow, in contact with the anterior loreal on one side (barely separated from it on the other); anterior loreal shorter and broader than the posterior; pre-frontals rather widely separated; frontal longer than broad, shorter
than the fused fronto-parietals, no interparietal; a pair of large nuchals and temporals behind the parietals; supraoculars four plus a small one posteriorly; ear opening and palpebral disk equal in size; fifth and largest supralabial beneath the eye, its length about three-fourths of its distance from the rostral; postmental longer than the mental; the anterior pair of chinshields in contact; scale-rows across the nape from ear to ear 10, around the middle of the body 28, from the parietals to the base of the tail 55; number of lamellae under the fourth toe 75 (Brown 1954).

Color: Head and mid-dorsal band (two to two and two half scale-rows in width) light greenish yellow or bronze anteriorly, becoming more greenish blue on the posterior half of the body before it merges into the light blue of the tail, heavily blotched with blackish-brown on the head and with scales dark bordered or with scattered spots of blackish brown; dorso-lateral stripes (one to one and one-half scale-rows in width) are also light greenish yellow anteriorly, greenish blue posteriorly, bordered above by a narrow blackish brown band (two half scales to two scale-rows in width) and below by a black-brown band beginning on the snout, passing through the eye and above the ear and ending in the region of the hind limb (generally two to two and one-half scale-rows in width along the flank). Frequent light spots occupying the area of a scale or less tend to mark those areas along the borders of the mid-dorsal and dorso-lateral stripes, giving a much more spotted appearance than is characteristic of Emoia schmidti.
The blackish brown bands tend to be continued on the blue tail as four series of dark blotches gradually disappearing toward the tip. The lower lateral surfaces are bluish; the venter is white or yellowish-white, faintly tinted with blue. The upper surfaces of the limbs are dark brown spotted with blue or bluish-green, the toes transversely barred with blue or bluish-white (Brown 1954).
