Nesolynx banabitanae is a newly discovered species of wasp found in Central Park, Salt Lake, Kolkata, West Bengal.
 
Key facts about Nesolynx banabitanae:

• The species was named Nesolynx banabitanae after "Banabitan," the local Bengali name for Central Park.
• It belongs to the family Eulophidae, which is known for diverse parasitic wasps.
• Nesolynx banabitanae is a hyperparasitoid, meaning it parasitises other parasitoid wasps rather than directly attacking herbivores or plants.
• This adds a fourth trophic level to the ecological interaction, contributing to multitrophic ecological dynamics.
• Advanced techniques such as scanning electron microscopy were used to study the wasp’s antennal sensilla, important for its sensory biology and host location.

The discovery has implications for biodiversity conservation and understanding parasitic wasp diversity in India.
