Rhotanella

Rhotanella is a small genus of planthoppers from the family Derbidae, tribe Rhotanini, with 8 species. The species are found in the Philippines, Indonesia, New Guinea, the Solomon Islands and southern China. The adult hoppers are between 4–6 mm long from head to the tip of the wings. They can be recognized by the shape and venation of their forewings which have a broad base and 5 very wide costal cells. Especially the first (basal) costal cell is very broad and has a width of about one quarter to one third of the width of the whole wing. The ridges on the sides of the face meet in front of the eyes. The profile of the head is also unusual for the tribe Rhotanini and has either an approximately rectangular or a somewhat triangular outline. The colour of the body is straw-coloured to light brown. The legs may be partly red or have red stripes. The forewings are brownish, but may have red marks in the costal cells. The forewings are carried in a roof-like position when the insects are at rest.
