oa Journal of the Entomological Society of Southern Africa - A new species of Pterandrus (Trypetidae, Diptera) from the Belgian Congo
The Ceratitis (s.l.) group of the Trypetidae with which the genus Pterandrus Bez.* is associated, is divided into various genera or what may perhaps be little more than subgenera. They are based mainly on certain male secondary sexual characters. Females may, however, to some extent be located in their correct genera on general appearance (brown colour, wing-pattern, etc.) but the inclusion of smaller, darker species in Pterandrus; gives rise to an unsatisfactory position.
