Oryctopterus varuna sp. nov.

Etymology The new species is named after Varuna, the god of rains in Indian mythology. The name is a noun in apposition. This cricket was observed coming out to open areas such as campus roads following rains, hence the name. In the regional dialect, Ot. varuna sp. nov. is called ‘Mannunni’, meaning ‘child of soil’. Also nicknamed ‘Thanni-Pillai’, meaning ‘baby of water’, alluding to its emergence following rains.
