The correct name of the African stem-boring stalk-eyed fly is Diopsis longicornis Macquart, 1835. Junior synonyms are tharacica Westwood, 1837, and phlogodes Hendel, 1923. Diopsis longicornis is a common rice stem borer throughout Ethiopian Africa. Damage often is compensated for by the growing rice plants. Other Diopsidae are mentioned as potentially important rice stem borers, among which is a stalk-eyed fly with apical wingspots. This fly has been identified as Diopsis apicalis Dalman, 1817, or Diopsis tenuiper Westwood, 1837. About 10 apicalis-like Diopsis are found in rice in Africa. Diopsis apicalis (syn. tenuipes) only occurs in West Africa, where it is the dominant Diopsis with an apical wingspot. There are some other closely related, dominant Diopsis with an apical wingspot that occur in rice, maize, and other gramineous crops that have yet to be described. These flies are secondary stemborers, and lay eggs on shoot with deadhearts or other damage
