Isomyia darwini (Curran, 1938)

= Strongyloneura darwini Curran, 1938: 3. Type locality: S. Rhodesia [Zimbabwe].

Seasonality: maximum abundance in November (three specimens) and almost absent the rest of the year. In Namibia, it was present in low numbers ( Kurahashi and Kirk-Spriggs 2006). Behaviour and ecology: observed at flowers in Zimbabwe by Cuthbertson (1939) (as S. darwini ) and also collected at flowers near Darwin (Zimbabwe) in March 1933 (Curran 1938 in Kurahashi and Kirk-Spriggs 2006). Life cycle and developmental stages: unknown. Collection methods: Malaise trap. In Namibia, with UV light and with Malaise and pitfall traps ( Kurahashi and Kirk-Spriggs 2006). Illustrations and photographs: female habitus as in Fig. 44 . Male terminalia as in fig. 16 in Zumpt (1958).
