with dark crossbars, hinder side of thighs may be
with round yellow spots which are usually separated by a dark brown/purplish network.

with single internal vocal sacs and nuptial pad
on base of 1st fi nger (enlarged 1st metacarpal
region).
Size: Male 3.4–5.7 and female 4.4–8.9 cm in
snout to vent length.
Tadpole
Mouth adapted for clinging with a sucker-like
disc; eyes on sides of head; tail muscular, long,
acutely pointed in fi lament form; body brown or
yellowish, irregularly mottled with dark brown
pigmentation.
Distribution
South Asia from sea level up to at least 1,500 m asl.
Localities in Doon Valley
Eastern Doon Valley: Motichur forest and Rajaji
National Park ( partim ).
Uttarakhand
Dehra Dun, Pauri, Uttarkashi and Almora.
Gobind Pashu Vihar and Rajaji National Park.
India
All over India (except Haryana, Punjab and
Rajasthan). Chhattisgarh, Eastern Ghats, Gujarat,
Himachal Pradesh, Madhya Pradesh and West
Bengal.
Elsewhere
Bangladesh; Bhutan; Nepal and Sri Lanka.
China and Myanmar (uncertain).
Habitat and Ecology
Found in a wide variety of habitat types including tropical dry and moist forests, grasslands and
agricultural areas and close to human habitations. It is largely arboreal, although it can be
found on walls and hidden under rocks and
leaves. Males have been reported calling from
the ground. It breeds in temporary pools and
paddy fi elds.
Conservation Status
IUCN Red List: Least Concern.
Threats
Habitat pollution by agrochemicals is the main
threat to the species. Otherwise, this species is
not facing any signifi cant threats.
Remarks
Dubois (1986/1987) considered Polypedates
himalayensis to be a subspecies of this species.
Conclusion
A total of ten species belonging to eight genera,
four families were collected from the Doon
Valley and all of these are found in the eastern
part while two species ( Hoplobatrachus crassus
and Polypedates maculatus ) were not encountered in the Western Doon Valley; may be some
more surveys reveal their presence in the area.
