Previously known as Conocephalus modestus. These three species of long-horned grasshoppers are often seen but there has been no review indicating there precise distributions since the 1970's. It appears that all three are basically in lowland grasslands. Conocephalus semivitatus has been found on the Kermadecs, Three Kings and throughout the North Island.
Conocephalus bilineatus is known from the Wellington area south to South Canterbury. Conocephalus albescens is a very widespread tropical to temperate species in the western Pacific and Australia yet so far it has been found mainly in the Nelson area.
