Key to species groups of Neoephydra

1. Lateroclinate, fronto-orbital setae 5–6; postocular setae well developed, prominent, particularly along ventral margin of eye....................................................................................The dasycephala Group - Lateroclinate, fronto-orbital setae 2; postocular setae variable but not prominent along ventral margin of eye............. 2

2. Setation generally weak, fronto-orbital setae much shorter than width of frons; mesofrons mostly microtomentose; antennal groove deeply impressed; disc of scutellum gray, contrasted distinctly with brown scutum........... The neotropica Group

- Setation strongly developed, length of fronto-orbital setae nearly equal to width of frons; mesofrons shiny with metallic reflections; antennal groove not deeply impressed; disc of scutellum concolorous with posterior portion of scutum..................................................................................................The araucaria Group
