Scientists in India have discovered a new spider species with distinctive red smile-like markings on its back in the Himalayan mountains of Uttarakhand, previously thought to exist only in Hawaii. Named *Theridion himalayana*, the spider was found at elevations above 2,000 meters and shows about 8.5% genetic variation from its Hawaiian relative, confirming it as a separate lineage that evolved independently in Asia. The study, published in *Evolutionary Systematics*, documented 32 color variations across three collection sites.
The accidental discovery occurred during an ant survey when researcher Ashirwad Tripathy sent images of spiders from high-altitude regions for identification. Co-author Devi Priyadarshini recognized the striking resemblance to the Hawaiian Happy Face spider she had studied during her master's program. DNA testing confirmed the Indian specimens belong to a distinct evolutionary branch that diverged from the Hawaiian population.
The function of the spiders' distinctive smile-like markings remains unknown, though researchers believe the color patterns aid survival. The spiders were frequently found on ginger plants, mirroring behavior observed in Hawaiian populations despite ginger not being native to Hawaii—a finding that has raised new questions about the species' evolutionary history.
