Zeugma is a small genus of planthoppers from the family Derbidae, tribe Zoraidini, currently (2024) with 9 species.
[6][7][8] The species of the genus Zeugma differ from the typical genera in the tribe Zoraidini by a number of unusual features.
[9] The genus was transferred to the Zoraidini by Fennah, mainly based on the venation of the forewings, specifically that of the cubitus and the clavus.
[10] Further, when at rest, the live insects do not raise their wings above the body like in most other species of the tribe Zoraidini, but hold them in a roof-like position.
[6][4][5] Type species: Zeugma vittata Westwood, 1840[1][11] Species of the genus Zeugma are found in central and western parts of Indonesia, in Malaysia, Thailand, Cambodia, the Philippines, Taiwan and in Assam (India).
[10] When live Zeugma species are at rest, they carry their wings in a roof-like position covering their abdomen.
[10][15] Due to the various differences to other genera in the tribe Zoraidini, the genus Zeugma has been placed in a separate subtribe, the Zeugmatina.
[16] Within the tribe Zoraidini, the species of Zeugma are of medium size, the body is around 5 mm long from the tip of the head to the end of the abdomen.
Zeugma elegans Muir, 1926[4] Described from Indonesia, Mentawai Islands (Se Pora, off West Sumatra), also reported from Singapore and mainland Malaysia.
General colour pale yellow; red in a rather broad band on pro- and mesonotum, on the vertex and on the ridges of face and postclypeus, also on the upper portion of the tegula; forewings pale yellow with black spots and lines.
Body straw-coloured, vertex, face, clypeus, middle of pronotum and scutellum red; front legs brown; forewings translucent, pale dirty yellow with lighter veins, media vein and bases of median branches as well as cross-veins brown.
[3][5] Head, pronotum, sterna and legs orange-yellow, some parts blackish or brown; forewings translucent, tinted with grey, a brown line covering cross veins of cubitus and media branches, another over the media vein and a third through the subcostal cell to the wing tip, a black line over apical cross veins.
