A revision of the hover fly genus Amphoterus Bezzi, 1915 (Diptera, Syrphidae) with the description of one new species

Abstract

Amphoterus Bezzi, 1915 is a genus of rarely collected Afrotropical hover flies (Diptera, Syrphidae). We present the first description of the female of A. braunsi van Doesburg, 1956, redescribe the males of A. braunsi van Doesburg, 1956 and A. cribratus Bezzi, 1915, and describe a new species, A. londtisp. nov. We also provide the first colour photographs of two of the species, the first DNA barcodes for the genus and a key to identify the species.
