Euphlyctis cyanophlyctis (Schneider)

(Fig 4G)

Specimens examined: eight males (WIIAD 057, WIIAD 238, WIIAD 279–284), three females (WIIAD 055–056, WIIAD 061).

Morphological features: Males SVL 38.1–44.7 mm (n=8) and females SVL 55.2–59.5 mm (n=3); body robust; head large and triangular, head slightly longer than wide; snout obtusely pointed in dorsal view; eyes large with rhombus pupil; tympanum round and 4/5 the diameter of eye, supratympanic fold distinct; dorsal skin tubercular; fingers pointed and without discs, relative length of fingers IV <II <I <III; toes long and fully webbed with relative length of toes 1 <2<3 <5 <4. Calling males had paired subgular vocal sac. Coloration in life: Dorsum grey or greenish brown with darker rounded spots; flank with white band; hind limbs cross-barred with dark grey; males have black paired lateral vocal sacs; ventral of body white with dark blotches. Vocal sacs of calling males were black.

Bioacoustics: 20 advertisement calls from two males were analyzed. Calls were recorded between 21:00–02:30 hours in July and August; and calling site air temperature was between 26°C–27.1°C. Calling males produced calls while staying on the surface of water in stagnant waterbodies. Calls delivery was sporadic and with non-regular intervals. The advertisement calls of E. cyanophlyctis consisted of two types of pulses (Fig 3). The calls had a mean duration of 583.95 ± 209.57 ms (200–946 ms) with a mean pulse rate 30.74 2.08 pulses/s (28.69–35.90 pulses/s). The mean dominant frequency was 1886.30 ± 624.49 Hz (1507.30–3057.70 Hz).

Remark: Common in PTR. Breeding was observed in ponds and stream pools in July and August.
