Description of the specimens from Myanmar.

Measurements and the comparison with the type specimens are represented in Table 2 View Table 2 . Habitus moderately slender, SVL 56.7-59.1 mm in males and 91.6-111.2 mm in females; head width slightly shorter than length (HW/HL 0.89-0.97); snout obtuse, pointed in dorsal view and rounded in profile, obviously projecting beyond lower jaw; position of nostril dorsolateral, closer to snout than eye; canthus rostralis distinct; loreal region concave and vertical; internarial distance greater than interorbital distance; snout length greater than eye diameter; pineal body distinct; supratympanic fold horizontal and straight; tympanum very large in males (TD/ED 0.71-0.78) and relatively small in females (TD/ED 0.56-0.62), round and transparent; vomerine teeth distinct; choanae close to the vomerine teeth. Tongue cordiform, posterior notch enlarged and formed as U-shaped; vocal sac openings visible on floor of mouth, in each corner; paired external vocal sacs present in males.

Forelimbs robust in males and relatively weak in females; relative lengths of fingers III> IV> I> II; all finger tips slightly expanded; lateral fringes and webbing on fingers absent; subarticular tubercle round and prominent; inner metacarpal tubercle and outer metacarpal tubercle distinct; greyish-yellow glandular nuptial pad on finger I in males.

Hind limbs long, tibia slightly longer than thigh; toes long and thin, relative lengths IV> V> III> II> I; all toe tips slightly expanded; entire webbing; subarticular tubercles prominent and longitudinally ovoid; inner metatarsal tubercle prominent and oval; outer metatarsal absent.

Dorsal skin smooth, lateral skin granular, ventral skin smooth. Dorsolateral folds distinct.

Colouration in life.

Dorsum greyish-brown, brownish-green or solid green with a few or many tiny black spots and several distinct or indistinct large black or brown spots. Upper and lower lips greyish-white, yellow, light green or brown with a few or many brown or black spots. Lateral side of head and body greyish-brown with many large or tiny black spots. Dorsal surfaces of limbs greyish-brown with some brown or black bands. Ventral surface of throat, chest and belly uniform white or some stains on ventral surface of throat, chest and anterior part of belly. Ventral surface of limbs white or pink. Tympanum brown, iris greyish-brown, pupil black.

Colouration in preservative.

In preservative, dorsum fades to greyish-black. Ventral surface of throat, chest, belly and limbs pale white. Iris black, pupil white.

Sexual dimorphism.

Body size much smaller in adult males than in adult females, adult males have relatively stouter forelimbs than females and greyish-yellow glandular nuptial pad on finger I, external vocal sacs present in adult males.

Natural history notes.

In Myanmar, all specimens of Odorrana macrotympana were found on the banks of large rivers. During December, we heard the courtship calls from males on the river banks at night, the sound of the calls being similar to those of other Odorrana species. We also observed males and females in amplexus on the banks of the rivers. No eggs or tadpoles were found.
