Overview
Comprehensive Description
Differential diagnosis
Afromicrodon is easily recognized among the microdons as 1) lacking an appendix on vein R4+5; 2) short antenna, about as long as face or shorter; 3) basoflagellomere simple; 4) scutellum simple, without calcar; and 5) abdomen oval.

Nomenclature and Synonymy
Included species: Ceratophya comoroensis De Meyer, De Bruyn & Janssons (1990: 571), Microdon johannae van Doesburg (1957: 109), Ceratophya madecassa Keiser (1971: 256) and Ceratophya stuckenbergi Keiser (1971: 258).
The species of Afromicrodon were previously and erroneously placed in the genus Ceratophya due to an error in Hull's world key to the genera of Microdontinae (1949: 306).

Afromicrodon is an African genus of hoverflies. The species of Afromicrodon were previously and erroneously placed in the genus Ceratophya.[1]
Afromicrodon are recognized among the Microdontinae as by lacking an appendix on vein R4+5. Having short antennae of about as long as the face or shorter, and a simple basoflagellomere and simple scutellum without calcar. The abdomen is oval.[1]
Distribution
All currently known species are restricted to Madagascar and Comoro Is.
