Rhyparida is a genus of leaf beetles in the subfamily Eumolpinae. It is mainly distributed in the Australasian, Oceanian and Indomalayan realms. It is most species-rich in Australia (about 100 species) and New Guinea (about 90 species), and reaches as far east as Samoa. Two species are also known from the African islands of Madagascar and Seychelles.
Description In general appearance, beetles of this genus are 3-5 mm long, shiny, and black or brown in colour.
Among Australian Eumolpinae, Rhyparida can be distinguished by the following features: head with groove above or along inner margin of eyes, sides of pronotal disc never swollen, head and pronotum with simple concave setiferous punctures, mid and hind tibiae excavate for about the last third of the outer margin and this excavation is fringed with stiff setae, tarsal claws bifid.
