Description
and Biology:
Long, narrow body, snout vent length male 51-64 mm, female
longer 69 mm. Head flat, wider than long; snout obtuse; nostril
between snout tip and eye; pupil vertical; tympanum indistinct;
internal naris large without vomerine teeth; first and second finger
equal in length; no subdigital tubercles; the tarsometatarsal joint
reaches in front of the shoulder; toes half webbed; dorsum
tuberculated with 1-7 large spiny warts at middorsum.
Sexually dimorphic, male with strong forlimbs, dark brown nuptial
spines on first three fingers, a pair of dark brown spiny chest
glands, a large spiny auxiliary gland and spines on the cloacal
region.
Scutiger nyingchiensis is morphologically distinguished from
the Pakistani frogs with hidden tympanum (Paa vicina, see key
in Khan, 2002) by the absence of dorsal longitudinal folds and having
heavily spinulated dorsum, presence of spiny auxiliary and chest
glands in male.
Color:
Dorsum grey olive, with dark brown triangular spots; sides of
body light yellowish;
limbs spotted; chest and abdomen greenish yellow.
Habitat,
Distribution
and Status:
There are 15 Scutiger species represented in China (Zhao et al.,
2000), of which one S. nyingchiensis extends into Kashmir and
northeastern Pakistan.
Subsequent to the specimen from Lun Bagla several specimen of S.
nyinchiensis has been collected from Gilgit and Deosai Plains by
Baig (personal communication, 04) and late W. Auffenberg (www.flmnh.ufl.edu).
Possible
reasons for amphibian decline:
General
habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Urbanization
Prolonged drought
Habitat fragmentation
Local pesticides, fertilizers, and pollutants
Long-distance pesticides, toxins, and pollutants
Predators (natural or introduced)
