by the structures of the male genitalia (aedeagal prongs fused medially), the presence of a V-shaped indentation on the dorso-median antepronotum, and the presence of a tuft of setae on the infra-halter sclerite (ventral to halter base and posterior to metathoracic spiracle), with the exception of females of one species. Furthermore, flies are relatively small with a wing length of 6.6-14.2 mm and the males exhibit a yellow to light brown abdomen, which is unusual for southern African

Males are unique in the arrangement of their medially fused aedeagal prongs and the yellow to light brown abdominal coloration. Females in contrast are more generalized and similar to other female

occurring in southern Africa. However, the antero-median V-shaped indentation on the antepronotum and the presence of white setae on the infra-halter sclerite are relatively easy to observe and distinguish the females from other
|
||
<taxonomicName family="Mydidae" lsidName="" pageId="0" pageNumber="1071" rank="family">Mydidae</taxonomicName>
|
||
. There is considerable sexual dimorphism and the setation, for example on the anatergites, is always easier to observe in males. Intra-specific variation in the abdominal coloration, especially in females, is likewise substantial, which probably led Hesse to describe a species twice.
