About Cnemaspis tropidogaster
Cnemaspis tropidogaster: The Rough-Bellied Day Gecko
The Cnemaspis tropidogaster, commonly known as the rough-bellied day gecko, is a species of gecko native to the Western Ghats of India and Sri Lanka. Its distribution within the southern Western Ghats is noted as patchy and the species is considered relatively uncommon in these regions.
Physical Characteristics
This diurnal lizard possesses a distinct head with an elongated snout, and its ventral scales are keeled. The dorsal side of the Cnemaspis tropidogaster is a dark brown, adorned with transverse arrangements of light and dark variegations. Its underside is typically pale brown or cream-colored, and it features spiny tubercles along its sides. Male individuals are identifiable by the presence of two to four preanal pores and three to six femoral pores.
Habitat and Ecology
The rough-bellied day gecko is a diurnal and crepuscular species, meaning it is active during daylight hours and also during twilight. It is commonly found in rocky substrates and on the low trunks of trees. Occasionally, this gecko has been observed entering man-made structures, such as thatched huts and cowsheds, indicating a degree of adaptability to human-altered environments.
Rediscovery and Distribution
Live populations of the Cnemaspis tropidogaster were notably rediscovered in Sri Lanka in 2016, after a gap of nearly 120 years. These rediscovered populations were located in a low elevation area (50–80 meters above sea level) within the wet zone of the island. Historically, it has been documented in the midhills of the Central Province's Knuckles Mountain Range, as well as in the Sabaragamuwa Province and parts of the monsoon forests in the Eastern Province of Sri Lanka.
