Diagnosis

Embidobia sankirna sp. nov. is close to E. jatayu sp. nov. but differs from it in having a spindle shaped metasoma; metascutellum is anteriorly foveate and posteriorly with depressions; submarginalis of fore wing is broken in front of marginalis. Whereas in E. jatayu metasoma is ovate; metascutellum is longitudinally costate and submarginalis of fore wing is not broken in front of marginalis.

Etymology

The Sanskrit epithet ‘sankirna’ means ‘narrow’ referring to the narrow metasoma. The name is treated as an adjective.
