A new species of spider discovered in the Indian Himalayas is attracting the attention of scientists due to an unusual detail: some of its markings on its back appear to form a kind of smile. The species was identified in Uttarakhand, in northern India, and received the scientific name Theridion himalayanain reference to the mountainous region where it was found.
The discovery was published in the scientific journal and describes a small, colorful spider with patterns that resemble the famous “happy-face spider” from Hawaii. Until now, these smiley-looking spiders were mainly associated with the Hawaiian Islands, but this new study shows that a similar group also exists in the Himalayas.
New species of spider was discovered almost by chance
According to the researchers, the discovery happened during fieldwork that, initially, did not even focus on spiders. Devi Priyadarshini, one of the study’s authors, explained that the research was related to ants, but the images sent by co-author Ashirwad Tripathy, collected in high altitude areas, ended up revealing an specimen with an unexpected appearance.
The researcher said that she immediately recognized the similarity with the Hawaiian spider with the “happy face”, which she already knew from her studies. From that moment on, more specimens and different patterns were collected, which led to the formal description of this new species found in the western Himalayas.
New species has 32 color variations
One of the most curious aspects of this spider is the wide variety of patterns found. The study identified 32 color variations, or “morphs”, in specimens collected from three locations in Uttarakhand: Makku, Tala and Mandal. The marks appear in combinations of red, black and white, creating different designs on the animal’s back.
In some specimens, these marks resemble a smiling face, which explains the comparison with the so-called “happy face” spider from Hawaii. Still, the researchers emphasize that it is not the same species, but a new Asian lineage, now scientifically described as Theridion himalayana.
DNA analysis confirmed difference between the Hawaiian spider
Despite the visual similarity, genetic analyzes revealed a difference of around 8.5% in relation to the Hawaiian spider Theridion grallator. For the authors, this data confirms that the Himalayan spider is a distinct species that evolved independently in Asia.
This conclusion makes the discovery particularly interesting for evolutionary biology, because it shows how similar patterns can emerge in very distant locations. The case raises new questions about the evolution of colors, body markings and survival strategies of these small arachnids.
Why does the spider have a “happy face”?
Despite the curious aspect, scientists still don’t know exactly what the function of these marks is. Devi Priyadarshini explained that the origin of this polymorphism is complex and that the patterns may help this new species to survive in the natural environment, but the concrete role of these “faces” in the spider’s life cycle remains to be clarified.
The authors admit that the phenomenon may hide a deeper genetic explanation. The presence of different patterns in the same group of spiders could be related to camouflage, defense against predators or other ecological factors that still need to be studied in more detail.
Found at more than 2,000 meters altitude
The name himalayan was chosen as a tribute to the Himalayas, a region known for its enormous biological diversity. According to researchers, the specimens were found in mountain areas above 2,000 meters in altitude, in environments with vegetation different from that found in the plains.
Scientists also report that these spiders have often been observed on ginger plants in the genus Hedychiuma connection that also aroused curiosity because there are parallels with Hawaiian species. For now, this relationship remains open and could be one of the lines of future research.
Discovery could pave the way for new investigations
The discovery of the “happy face” spider in the Himalayas shows that there is still a lot to be known in mountainous and little-studied regions. For the authors, this new species can help to better understand how certain visual patterns evolve and how small animals adapt to high-altitude habitats.
