Neoeurys species identification
Workbook
Note: This is a “work in progress”. Changes may be made as I discover additional relevant information.
Identification of species in genus Neoeurys
The matrix below is designed to aid identification of species in the genus Neoeurys, which has the following diagnostic features (see Euryinae genera matrix for diagrams illustrating these features):
most species (15/20) have a metallic coloured thorax
antennae filiform with flagellum longer than breadth of head
antenna with 10-14 segments
antenna inserted well below level of middle of eyes
first transverse vein received before the middle of the discoidal cell
(Note that the recent combined molecular and morphological phylogenetic study of Schmidt and Walter, 2014 suggests that the separation of Neoeurys and Eurys is unjustified and that these taxa should be combined into a single genus).
