Sikaianini

The Sikaianini is a small group (tribe) of planthoppers in the family Derbidae with a total of 6 genera and 34 species, as of 2025. They are mainly found in tropical regions around the world. Most species have been described from islands in southeastern Asia (the Philippines, eastern Indonesia, Palau and Taiwan), from northeastern Australia, and from the southwestern Pacific (Fiji, Samoa, the Solomon Islands and New Caledonia). Additional species are known from mainland Asia (Vietnam) and the Seychelles (one each), from West Africa (two), from North America (two) and one from the Caribbean. The members of the Sikaianini are small and delicate insects with a body length of around 2 mm and a typical forewing length of 4–6 mm. They frequently have a light coloration, and translucent forewings with some darker marks. They can be distinguished from the other tribes of the Derbidae by the shape of the eyes which reach the clypeus in front, the forewing venation and the short hind wings which sometimes seem to be used for stridulation only. The adult hoppers have been found feeding on different types of palm trees.
