(Fig 4 I) Specimens examined: one adult male (WIIAD 228). Morphological features: An adult male, SVL 153.9 mm; body large and stout; head marginally longer than wide; snout obtusely pointed in dorsal view and projecting beyond mouth; tympanum distinct, nearly equal to the diameter of eye, prominent supratympanic fold; arms short and strong; dorsal skin glandular with broken longitudinal ridges; finger tips without discs, relative length of fingers II <IV <I <III; toes nearly full webbed, webbing formula I 0 – 0 II 0 – ½ III ½ – ½ IV ½ – ½ V), relative toes length 1 <2 <3 <5 <4, inner metatarsal tubercle present. Coloration in life: Adult male pale brown or greyish (lemon yellowish during breeding season) with dark plump spots on dorsum; prominent greenish or pale yellowish stripe from behind the eye to the groin; a white streak on upper jaw; hind limbs cross-barred with four prominent bands; ventral sides pale white. Males had distinct blue paired subgular vocal sac which is likely to be an optical cue for attraction of females (Gomez et al. 2009; Fig 4 I). Bioacoustics: We analysed 50 advertisement calls from five males of H. tigerinus. The males were recorded calling between 23: 30 – 03: 00 hours in July and site air temperature was between 26 ° C – 28.5 ° C. The mean call duration of analysed calls was 235.30 ± 48.65 ms (181 – 430 ms). Recorded mean pulse rate was 76.92 ± 5.32 pulses / s (61.82 – 87.18 pulses / s) with 17.36 ± 2.88 pulses (13 – 29 pulses) delivered per call. The mean dominant frequency was 1819.14 ± 388.87 Hz (1205.90 – 2239.50 Hz).
