Identification of species in genus Eurys

The matrix below is designed to aid identification of species in the genus Eurys, which has the following diagnostic features (see Euryinae genera matrix for diagrams illustrating these features):

very long tongue when extended for sucking nectar - as long or longer than front tibia
thorax with bright metallic colour - green, copper or violet
antennae are filiform with between 8 to 11 segments
antennal insertion point is level with the middle of the eyes
the first transverse vein is received close to the middle of the discoidal cell
