Ornebius sp. (genus) (Scaled Cricket)

Otte and Alexander 1983 (Monographs Acad. nat. Sci. Philad. 22) give the following diagnostic criteria for subfamily Mogoplistinae to which this genus belongs: body length 4-13mm, body covered in scales, pronotum relatively long, male forewings rarely reaching end of abdomen, hindwings absent, females always wingless, hind tibiae without moveable spurs. Ornebius is the largest genus in this taxon and is defined by the following features: body length more than 7.5 mm; last dorsal segment of abdomen not black between cerci; genital processes brown to pale brown or whitish; posterior margin of forewings with continuous black or brown band or with 3 darkened areas; tibiae I and II slightly or strongly banded. Species in the Illaroo Group have the following features: legs I and II strongly banded; face usually with contrasting markings; 10th tergite of abdomen usually with two tufts of setae near centre; forewings often with 3 dark marks along posterior margin.
