Abstract

Zigrasimecia ferox sp.n. is described and illustrated based on workers fossilized in 99 million-year-old Burmese amber. The new specimens allow the confident assignment of Zigrasimecia BARDEN & GRIMALDI, 2013, a genus recently described based upon a gyne from the same amber deposit, to the extinct subfamily Sphecomyrminae, and more specifically to the tribe Sphecomyrmini.
