Jayanti spider cricket

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

More about the insect-

It was found in the Kurra caves of Chhattisgarh in April 2021 by a team of zoologists of Panjab University, Chandigarh.
The new subgenus was named Jayanti after Professor Jayant Biswas, one of the leading cave explorers in the country, who assisted the team.
Arachnomimus is the genus name given by Swiss Entomologist Henri Louis Frédéric de Saussure in 1878 to crickets that resembled spiders.
The word Arachnomimus is derived from two Ancient Greek words arakhne means “spider” and mimos, means “imitator, actor”.
The crickets of this group are commonly called spider crickets because of their smaller body size and long legs.
The newly discovered subgenus, Indimimus, is different from the two subgenera, Arachnomimus and Euarachnomimus because of the male genitalia structure.
Insects have a lock-and-key model genitalia structure which is unique to each subgenus.
Male crickets produce loud sounds by rubbing their wings against each other to attract females.
The females listen to these calls using ears located on their legs and approach the males for mating and reproduction.
But males of the new Jayanti subgenus cannot produce sound and their females don’t have ears.
They may communicate by beating their abdomen or any other body part on the cave walls.
Further studies on their skills of vibrational communication may help in designing hearing aids for humans which can capture quietest signals and amplify to an audible hearing range.
Though the distribution of these species is very wide, ranging from Brazil to Malaysia, in India, the diversity of spider crickets is still unexplored.
