Diostrombus

Genus of planthoppers

Diostrombus is a large genus of planthoppers from the family Derbidae, tribe Zoraidini, with more than 40 species. The large majority of species have been described from Africa and the Near East. However, a few species, including the type species, are found in southern and eastern parts of Asia. In Africa, the distribution range of Diostrombus species extends from the humid tropics of western Africa to many parts of eastern Africa, as far north as parts of Sudan and as far south as South Africa. Three species have been described from Yemen and the Iran. Like other species of the tribe Zoraidini, species of Diostrombus have long and narrow forewings and short hind wings. The main characteristic of Diostrombus is the forewing venation with the media vein having 6 branches which do not split further into sub branches. The hind wings are much shorter than half the forewing length and have a pointed tip. In profile the head is usually flat, but in some African species, the ridges on the sides of the face are extended in front of the antennae. The face is narrow. The antennae are short compared to other genera of the tribe Zoraidini, about half as long as the face.
