Posterior margin of forewing with a continuous dark band or three darkened areas, brown or black, never red. Tibia I and II banded. Front of mirror not hidden beneath pronotum. Etymology The meaning of the name Ornebius is unknown. Ornebius is male gender. Measurements See Table 8. For a detailed description of Ornebius in the Australian region, see Otte & Alexander (1983: 386); Rentz & Su (2019: 273). Habitat and ecology Nocturnal crickets, arboreal; their melodious song is heard in the foliage of trees and shrubs. Distribution New Zealand: New Plymouth, Auckland, Northland and Coromandel; Kermadec Islands. The mainland populations are introduced from Australia.
