Abstract
The Australian planthopper genus Monomalpha Emeljanov, 2000 is reviewed. Males of M. gratiosa Emeljanov, 2000, a species originally described from a single female specimen, are presented for the first time. A new species, M. stenocara from Queensland is described. Together with the type species M. gratiosa, recorded from Queensland and mainland NSW, and M. fletcheri Emeljanov, 2000, a species endemic to Lord Howe Island (New South Wales) there are now three species recognised in the genus Monomalpha. A new endemic genus, Latissima gen. nov., is created within Cixiini to accommodate a new species from Queensland, Latissima isleyensis sp. nov. Identification keys to the genera of Australian Cixiini and to the species of Monomalpha are presented and host plant relationships discussed, including the first record of an Australian cixiid from the tree fern family Cyatheaceae.
