About Cyrtodactylus marmoratus Gray, 1831
Head Shape & Proportions
This species has a large, depressed head with a pointed snout that is longer than the orbit diameter; the orbit diameter equals the distance from the orbit to the ear-opening. The forehead is concave, and the ear-opening is oval, oblique, and around one third the diameter of the eye.
Head Scales & Tubercles
The head is covered in granular scales, with small tubercles on the occiput and temples; the granules are enlarged on the snout. The rostral scale is subquadrangular, roughly twice as broad as it is high, with a median cleft on its upper edge.
Nasal & Labial Scales
The nostril is bordered by the rostral scale, the first labial scale, and 4 or 5 other scales. There are 12 upper labials and 10 lower labials.
Mental & Chin Scales
The mental scale is triangular, and there are two or three pairs of chin-shields; the median chin-shields are the largest and contact each other behind the mental scale. The throat is covered in very small granules.
Body Shape & Dorsal Scales
The body is elongate. The dorsal surface of the body is covered in small granules mixed with small, round, feebly keeled, subtrihedral tubercles.
Lateral Fold & Ventral Scales
A lateral fold is present, sometimes very indistinct, and bears a few slightly enlarged tubercles. Ventral scales are small, smooth, cycloid, and imbricate, with 40 to 45 ventral scales across the middle of the belly.
Male Reproductive Pores
Males have 12 or 13 preanal pores arranged in an angular, inverted V-shaped series within a longitudinal groove, plus 4 to 6 femoral pores on each thigh, separated from the preanal pores.
Tail Morphology
The tail is round and tapering; it is covered with uniform small, flat scales, and has rows of 4 to 6 keeled, trihedral tubercles at its base.
Limb & Digit Structure
The limbs are elongate. The digits are strong, slightly depressed at the base, which bears enlarged transverse plates on the inferior side, and compressed in the distal portion.
Dorsal Body Coloration
The dorsal surface is light brown, with dark brown spots along the back that sometimes form cross bands. The head has irregular dark markings, including a dark temporal streak.
Tail & Underside Coloration
The tail has dark brown annuli. The underside is yellowish-white, with each scale speckled with dark brown.
Size Measurements
The combined length of the head and body is 76 mm, and the tail is 72 mm long.
