Explanation:

Jayanti has become the twelfth subgenus, or species, of cricket identified under the genus Arachnomimus Saussure, 1897.

• It was found in the Kurra caves of Chhattisgarh in April 2021 by a team of zoologists.
• It was named Jayanti after Professor Jayant Biswas, one of the leading cave explorers in the country, who assisted the team.
• Interestingly, males of the new Jayanti subgenus cannot produce sound and their females don’t have ears.
• Arachnomimus is the genus name given by Swiss Entomologist Henri Louis Frédéric de Saussure in 1878 to crickets that resembled spiders.

Hence only statement 2nd is correct.
