Environment

In March 2025, scientists from the Kolkata (West Bengal)-based Zoological Survey of India (ZSI) discovered a new species of soil-dwelling nematode named ‘Crassolabium dhritiae’ in the Deccan Peninsula biogeographic zone located in Keonjhar, Odisha.


      - The discovery, published online in Acta Zoologica Bulgarica, highlights the rich and often overlooked biodiversity of this region, emphasizing the ecological significance of nematodes in maintaining healthy soil ecosystems.

      - The species is named ‘Crassolabium dhritiae’ in honor of Dr. Dhriti Banerjee, the Director of ZSI, recognizing her remarkable contributions to taxonomy and zoological research.

     

Main Point :-   (i) This nematode is characterized by a medium-sized slender body, rounded lip region, large odontostyle, long pharynx, and distinct features in the female reproductive system, along with a uniquely shaped tail.

      (ii) Members of the Crassolabium genus display omnivorous and predatory behavior, although detailed research is ongoing to better understand their feeding habits.

(iii) With the addition of Crassolabium dhritiae, the global count of species in the Crassolabium genus rises to 39, including 9 species reported from India.
