The three taro planthoppers: species recognition in Tarophagus (Hemiptera: Delphacidae).
The taro-feeding delphacid genus Tarophagus is revised. Three species are recognized: T. colocasiae stat. rev. & comb. nov. with which T. proserpina taiwanensis is synonymized; T. persephone with which T. proserpinoides and T. proserpina australis are synomymized; and T. proserpina. The three species are separated by characters of the male and female genitalia, and each has a different distribution in Asia and the Pacific. Only in Papua New Guinea are all 3 species sympatric. Earlier studies on biology and pest status are reviewed in the light of these investigations.
