About Draco maculatus (Gray, 1845)
Head Morphology
Draco maculatus (Gray, 1845) has a small head, with a snout that is slightly longer than the diameter of the orbit. Its nostril is positioned laterally and directed outwards, and the tympanum is covered in scales.
Upper Head Scales
Upper head scales are unequal and strongly keeled, with one compressed, prominent scale located on the posterior part of the superciliary region, and there are 7 to 11 upper labials.
Male Gular Appendage
Males have a very large gular appendage, which is always much longer than the head, and frequently twice as long as the head.
Female Gular Sac
Females also have a well-developed, though smaller, gular sac.
Male Nuchal Crest
Males have a very small nuchal crest.
Body Scales
Dorsal scales are only slightly larger than ventral scales, are irregular in shape, and are either smooth or very feebly keeled. On each side of the back runs a series of large, trihedral, keeled, widely spaced scales.
Limb Lengths
When stretched forwards, the fore limb extends beyond the tip of the snout; when held against the body, the hind limb reaches a little past the elbow of the adpressed fore limb, or reaches the axilla.
Dorsal Body Coloration
The dorsal body surface is greyish, with more or less distinct darker markings, and a more or less distinct darker interorbital spot.
Wing-Membrane Markings
The upper surface of the wing-membranes has numerous small round black spots, which rarely run together; the underside of the wing-membranes is either immaculate or has a small number of black spots.
Gular Appendage Spot
One blue spot is present on each side at the base of the gular appendage.
Size Measurements
The species measures 82 mm (3.2 in) from snout to vent, with a tail length of 115 mm (4.5 in).
Geographic Range
Its geographic range extends from Assam and Yunnan to Singapore, including southern China (Hainan, Guangxi, Yunnan, Tibet), India (from the Eastern Himalayas to Assam), Bangladesh (Satchari National Park, Sylhet), Myanmar, Laos, Vietnam, Thailand and Western Malaysia.
