About Eutropis rugifera (Stoliczka, 1870)
Eutropis rugifera has a short, obtuse snout, with scaly lower eyelids. The nostril sits behind the vertical level of the suture between the rostral and first labial scales; there is no postnasal scale. The anterior loreal scale is not deeper than the second loreal, but much smaller in size. The frontonasal shield is broader than it is long, and makes large contact with both the rostral and the frontal shields. The frontal shield is longer than the frontoparietals and interparietal combined, and contacts both the first and second supraoculars. There are 4 supraoculars total, with the second being the largest; there are 6 supraciliaries, with the first being the largest. The frontoparietals are distinct, and larger than the interparietal. One pair of nuchal scales is present. There are 5, or sometimes 4, labial scales located anterior to the subocular; the subocular is large and not narrower at its lower edge. The ear opening is very small, oval, and oriented horizontally, surrounded along its border by projecting granules. The dorsal, nuchal, and lateral scales are all very strongly quinquecarinate. There are 26 scales around the midbody, 8 to 10 of which are smooth. When adpressed against the body, the hind limb reaches the elbow of the adpressed fore limb. Subdigital lamellae are smooth. Scales on the upper surface of the tibia are bicarinate. The tail is 1.6 times the length of the head and body combined. The species is dark olive-brown on its upper surfaces, and greenish-white on its under surfaces. The snout-to-vent length ranges from 2 to 5 inches; the tail measures 4.5 inches. Eutropis rugifera is distributed across the Nicobar Islands (India), the Malay Peninsula including southern Thailand, Peninsular Malaysia, and Singapore, the Sunda Islands including Sumatra, Nias, the Mentawai Islands, Java, and Bali in Indonesia, and Borneo shared between Indonesia and Malaysia, plus Mindanao in the Philippines.
