Diagnosis

Embidobia yuyutsu sp. nov. is close to E. hiranya sp. nov. but differs from it in having T2 and T3 of equal length; metascutellum is evenly rounded posteriorly and is anteriorly foveate and posteriorly with depressions. While in E. hiranya . T3 is longer than T2 and metascutellum is posteriorly protruding and is anteriorly foveate and posteriorly longitudinally costate.

Etymology

The species epithet ‘yuyutsu’ refers to Yuyutsu, born out of wedlock from the union of king Dhritharashtra and his wife’s maid Sugadha, the only one among his sons who survived the Kurukshetra war in the Indian epic Mahabharatha. The name is treated as a noun in apposition.
