Diagnosis

Embidobia hrdaya sp.nov. is close to E. omkara sp. nov. but differs from it in having a short metasoma and a mesoscutellum which extends beyond posterior margin of metascutellum; while in E. omkara metasoma is longer and the mesoscutellum extends just up to posterior margin of metascutellum.

Etymology

The Sanskrit epithet ‘hrdaya’ means ‘heart’ referring to the shape of the mesoscutellum. The name is treated as an adjective.
