Round brackets are used to indicate that a species is currently placed in a genus different to the one in which it was originally described . For example: Liriomyza amoena (Meigen, 1830). Meigen (1830) originally descriped this species as Agromyza amoena. Nowadays it is placed in the genus Liriomyza Mik, 1894. Hence, 'Meigen, 1830' is placed in round brackets. Sometimes the original placement is given, thus Liriomyza amoena (Meigen, 1830: Agromyza).
