- Fejervarya orissaensis (Dutta) (Fig 4D) Specimens examined: two males (WIIAD 227 & WIIAD 249) and an individual with sex undetermined (WIIAD 066). Morphological features: Adult males SVL 42.7–42.9 mm (n=2) and an individual (sex unknown) SVL 39.4 mm; body robust; head slightly longer than wide; snout obtusely pointed in dorsal view; eyes large; tympanum distinct, nearly 1⁄2 the diameter of eye, distinct supratympanic fold; tubercles present on dorsal and lateral body, short longitudinal ridges on mid-dorsum, fejervaryan lines on abdomen; fingers without disc and rounded, relative length of fingers II = IV <I <III; poorly developed toe webbing, toes tips rounded, relative length of toes 1<2<5<3<4, inner metatarsal tubercle elongated. Calling males had subgular paired vocal sac. Coloration in life: Brown dorsum with dark grey spots; fore limb and hind limb cross-barred with dark grey; upper and lower jaws marked with bands; pale yellow mottling on posterior thigh; ventral side of body white. Vocal sac of calling male was black. Bioacoustics: We analysed 50 advertisement calls from five males. Calls were recorded between 22:40–00:20 hours and calling site air temperature was between 26.9°C–29.9°C. The calls were pulsatile and emitted mostly at regular intervals. The calling males produced single type calls with mean call duration of 98.76 ± 8.69 ms (82–109 ms). The pulse rate was 104.46 ± 2.03 pulses/s (94.59–107.53 pulses/s) with mean of 9.76 ± 0.98 pulses per call. The mean dominant frequency was 2412.59 ± 6.34.95 Hz (1162.80–2842.40 Hz). Remark: Common in PTR. Breeding observed in seasonal rainwater puddles in paddy fields in July. The presence of this morphologically cryptic anuran is genetically confirmed in this study (Fig 8A). This is the north-westernmost confirmed record of this species in its range (780 kilometers aerial distance from type locality in Orissa), and a new state record for Madhya Pradesh state.
