The discovery of the new lizard species, Calotes wangi, in southern China and northern Vietnam has unveiled fascinating insights into its habitat and unique characteristics. Named after its distinct features, this agamid species stands out due to its morphological traits and genetic diversity, as extensively studied by scientists analyzing mitochondrial genes (tRNA, ND2, and CO1).
Exhaustive Fieldwork
Over a span of more than 13 years (2009 to 2022), researchers conducted exhaustive fieldwork in various provinces and regions, including Yunnan, Guangdong, Fujian, Hainan, and Guangxi Zhuang. Their meticulous efforts led to the collection of 323 specimens, accompanied by comprehensive data acquisition involving live animal observations, DNA extraction, and sequencing, crucial in confirming the species as novel finds in scientific realms.
Intriguing Physical Attributes
Photographs of live specimens and their habitats, alongside detailed examination, have highlighted intriguing aspects of Calotes wangi's behavior and physical attributes. Males, measuring about 90 mm snout to vent in adulthood, showcase distinguishing features like scales between the nasal shield and orbit, as well as a fourth toe with a claw that extends between the eyes and tympanum, setting them apart from their counterparts, particularly C. irawadi.
Coloration Transformations
The lizard's coloration undergoes fascinating transformations, notably during breeding seasons and episodes of stress. Adult males display vivid hues of dark orange, black patches on their necks, and khaki to dark khaki tones on their bodies and toes during mating periods. In non-breeding times, their coloration shifts to dark or lighter khaki with distinctive black markings. Females, on the other hand, sport a uniform pale khaki with horizontal stripes and a radial stripe around the eyes, lending a unique aesthetic to this newly discovered species.
Habitat Diversity
This agamid thrives in diverse habitats, predominantly sub-tropical broad-leaved forests and tropical monsoon forests across southern China and northern Vietnam. It finds its niche in mountainous regions, hills, and forest edges, showcasing adaptability and resilience within these varied landscapes.
