New Ant Species Discovered in Western Ghats

January 3, 2025

A recent discovery in the Western Ghats has brought attention to the biodiversity of leaf litter ecosystems. Scientists from Goa, Karnataka, and Dehradun identified a new ant species named Tapinoma onaele in Kodagu district, Karnataka. This discovery marks the importance of leaf litter, which is often overlooked. The name ‘Onaele’ translates to ‘dried leaves’ in Kannada, signifying the crucial role of this habitat. Pronoy Baidya, the head of the research division at AERO, emphasised the leaf litter’s biodiversity as a vital component of forest ecosystems.

Importance of Leaf Litter Ecosystems

Leaf litter is often dismissed as a lifeless zone. However, it serves as a habitat for countless organisms. This microhabitat supports various ecosystem functions essential for forest health. Leaf litter contributes to nutrient cycling, water retention, and soil formation. It acts as a shelter for insects, fungi, and microorganisms, which are integral to the forest’s food web.

Recent Ant Discoveries in Goa

Baidya has documented 133 ant species in Goa. Notably, Probolomyrmex procne was rediscovered after three decades. This species has only been documented in two other locations in India. The specimens were collected in Netravali Wildlife Sanctuary during the post-monsoon season. The discovery puts stress on the rich biodiversity found in Goa’s forests.

Identification of Tapinoma onaele

The new ant species, Tapinoma onaele, was identified based on its unique morphological features. It shares similarities with Protanilla lini but can be distinguished by its shorter antennal scape. The research involved meticulous measurements of various physical characteristics to ensure accurate identification. This discovery adds to the known diversity of the Protanilla genus in India.

Protanilla flamma is commonly called Vaibhav’s Protanilla.
The elevation of the collection site for Probolomyrmex procne was 445 m above sea level.
Baidya’s research area covered 2,500 sq km in Goa.
Leaf litter can support millions of organisms.
Protanilla wardi is closely related to Tapinoma onaele.

Conservation of Leaf Litter Habitats

The destruction of leaf litter through burning poses threat to biodiversity. It is crucial to recognise the ecological value of leaf litter ecosystems. Conservation efforts should focus on protecting these habitats to ensure the survival of many species. Raising awareness about the importance of leaf litter can encourage better environmental practices.
