Eutropis rugifera (Stoliczka, 1870)

Snout and Eyelid Features

Eutropis rugifera has a short, obtuse snout, with scaly lower eyelids.

Nostril and Postnasal Scale Characteristics

The nostril sits behind the vertical level of the suture between the rostral and first labial scales; there is no postnasal scale.

Loreal Scale Proportions

The anterior loreal scale is not deeper than the second loreal, but much smaller in size.

Frontonasal Shield Morphology

The frontonasal shield is broader than it is long, and makes large contact with both the rostral and the frontal shields.

Frontal Shield Features

The frontal shield is longer than the frontoparietals and interparietal combined, and contacts both the first and second supraoculars.

Supraocular and Supraciliary Counts

There are 4 supraoculars total, with the second being the largest; there are 6 supraciliaries, with the first being the largest.

Frontoparietal and Interparietal Scales

The frontoparietals are distinct, and larger than the interparietal.

Nuchal Scale Presence

One pair of nuchal scales is present.

Labial and Subocular Scale Traits

There are 5, or sometimes 4, labial scales located anterior to the subocular; the subocular is large and not narrower at its lower edge.

Ear Opening Morphology

The ear opening is very small, oval, and oriented horizontally, surrounded along its border by projecting granules.

Dorsal, Nuchal and Lateral Scale Structure

The dorsal, nuchal, and lateral scales are all very strongly quinquecarinate.

Midbody Scale Counts

There are 26 scales around the midbody, 8 to 10 of which are smooth.

Limb Adpression Range

When adpressed against the body, the hind limb reaches the elbow of the adpressed fore limb.

Subdigital Lamellae Traits

Subdigital lamellae are smooth.

Tibia Scale Morphology

Scales on the upper surface of the tibia are bicarinate.

Tail Length Proportion

The tail is 1.6 times the length of the head and body combined.

Body Coloration

The species is dark olive-brown on its upper surfaces, and greenish-white on its under surfaces.

Size Measurements

The snout-to-vent length ranges from 2 to 5 inches; the tail measures 4.5 inches.

Geographical Distribution

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.
