Losbanosia

Losbanosia is a small genus of planthoppers from the family Derbidae, tribe Zoraidini, currently (2024) with 5 species. The species are found in eastern Asia from Japan and southern parts of far-eastern Russia in the North to the Philippines and "Indo-China" in the South. They can be easily recognized by the wavy or serrated hind margin of the forewings which is unique in the tribe Zoraidini. The shape of the forewing is further unusual in its club-like outline, forming a distinct angle at the hind margin, around one third from the wing base. The hind wings are much shorter than half the forewing length, with a large anal area bearing a stridulation plate. Like in other genera of the tribe Zoraidini, live specimens of Losbanosia raise their wings above the body, but spread them out widely. The face is narrow and linear and the antennae are longer than the face. The typical colour of the body is brown to reddish brown, the legs and the rostrum are straw-coloured. The forewings are transparent with dark brown areas near the wing base, near the tip of the wing, along sections of the hind margin, as well as near the costal margin which connects to a triangular mark near the middle of the wing. The forewing veins are red in the dark brown areas, but yellowish in the transparent parts. All species of Losbanosia are similar in colouration and the species need to be identified by the structures on the tip of the male abdomen.
