Description
First finger hardly extends beyond second; tibiotarsal articulation reaches anterior border of eye or a point between it and the tip of snout.

Color: Grayish dorsum, with dark spots, sometimes with reddish and orange suffusion, a light narrow middorsal line is often present. Ventrum white. During the breeding season, the male gular region is black.

Tadpole: Medium sized tadpole, Khan (1991a, 1996a) finds no apparent morphological difference from that of Limnonectes limnocharis.

Limnonectes syhadrensis occurs sympatrically in most of its range in Pakistan with Limnonectes limnocharis, which becomes rarer in the lower Indus Valley. L. syhadrensis is widely distributed throughout southern India.

Life History, Abundance, Activity, and Special Behaviors
Limnonectes syhadrensis abounds in paddy fields, marginal vegetation of ponds, puddles and streams in plains. It become rarer in northern hilly tracts along sub-Himalayan ranges. Its call is typical, like the clatter of a typewriter, a loud "Trr, trr, trr, trr, trr", repeated several times. The calling males sit quite apart from each other, away from the water, in the roots of marginal vegetation. Calling is triggered by the first monsoon downpour when water temperature reaches 20o C. Egg diameter ranges from 0.8 to 1.2 mm. Eggs are laid in small batches, embeded in gelatinous material, each enclosed in double jelly capsule. Eggs soon separate and adhere to the grass blades (Khan 1996a).

Trends and Threats
Use of perticides affects breeding.

Relation to Humans
Exterminates crop pests and their larvae.

Possible reasons for amphibian decline

General habitat alteration and loss
Urbanization
Prolonged drought
Drainage of habitat
Local pesticides, fertilizers, and pollutants
Long-distance pesticides, toxins, and pollutants
Predators (natural or introduced)
