Comments. Decevania deansi sp. nov. differs from the others species by having eye developed, bulging and subrounded; gena narrow in lateral view; flagellomere I long; notaulus polished; stigmal vein narrow; stigmal vein + 1R1 vein long and 1R1 dilated distally.

Variation. Specimens from Panama have anterior ocelli translucent, mandible, tegula and petiole light castaneous; vein 1R1 as longer as stigmal vein and declivity of propodeum with convex profile.

Distribution. Panama and Venezuela.

Etymology. This species is named after Andrew R. Deans for his contribution to the study of Evaniidae .
