Scientists from the Zoological Survey of India (ZSI), Kolkata, have announced the discovery of a species of soil-dwelling nematode in the Deccan Peninsular biogeographic zone of Odisha’s Keonjhar district.

The newly identified species, Crassolabium dhritiae, is named in the honour of Dr Dhriti Banerjee, Director of the ZSI, in recognition of her outstanding contributions to zoology and taxonomic research.

The discovery was made by a research team led by Dr Debabrata Sen, along with Dr G P Mandal and Samprit Deb Roy from ZSI, Kolkata.

Dr Banerjee emphasised the importance of soil nematodes, saying, “These microscopic organisms, though often overlooked, are vital to soil health and play a crucial role in nutrient cycling and organic matter decomposition. Their diverse feeding habits significantly contribute to maintain a balanced and healthy soil ecosystem.”

Crassolabium dhritiae is characterised by its medium-sized, slender body, rounded lip region, wide odontostyle, long pharynx, specific features in its female reproductive system, and a distinct tail shape. While the feeding habits of the Crassolabium genus are still being studied, they are known to include predatory and omnivorous behaviors.

Dr Sen said, “This discovery is a significant addition to our understanding of nematode biodiversity. Crassolabium dhritiae brings the total number of known Crassolabium species worldwide to 39, with nine now recorded in India. This highlights the importance of continued research in these understudied ecosystems.”
