Twelve genera and 43 species are recognized in the tropical regions of Africa and Asia; descriptions and keys for their separation are provided. Four genera and 16 species are described as new. Three new synonymies are established at the genus-level and four at the species-level; 10 new combinations are established; two 'forms' are raised to the status of species and nine lectotypes are designated. Introduction Plant-feeding bugs of the family Coreidae are characteristic inhabitants of the herb and shrub layers of tropical and, to a lesser extent, of temperate ecosystems. They are frequently encountered in surveys of crop pests, since most of the world's tropical crops are herbs or shrubs, and are usually represented in collections made during ecological studies in the tropics. Most of the literature available for the identification of Coreidae is out of date, fragmentary or lacks identification keys. Pseudophloeinae may be recognized, with a little practice, by their general habitus and size, and by the absence of a dorsal sulcus on the tibiae; other groups of Coreoidea lacking tibial sulci Bull.
