A bit of a guess Promachus sp. Wing venation and the fact there is gap between the antennae.

Thanks! Genus is usually enough for me... Unfortunately, I now have two quite different flies filed as possible Promachus, from the same location, so I'm going to have to do something about this... According to the Biosystematic Database of World Diptera, there are... several species of Afrotropical Promachus... (Madagascar endemics and one species known only from Eritrea not included)... Promachus abdominalis (Malawi) Promachus adamsii (Zimbabwe, Kenya, Uganda) Promachus aequalis (S. A., Kenya, Malawi, Mozambique, Zimbabwe, Tanzania) Promachus albicinctus (S. A.) P. apicalis (Zimbabwe) P. argentipennis (Sudan) P. aurulans (Tanzania) P. binucleatus (Ethiopia) P. bomensis (Congo) P. bottegoi (Ethiopia) P. brevipennis (Uganda) P. breviventris (Kenya, Tanzania) P. chalcops (Tanzania) P. cinereus (Zimbabwe) P. enucleatus (Tanzania) P. flavopilosus (Malawi, Uganda) P. floccosus (Nigeria) P. gossypiatus (Tanzania, Malawi) P. grisiventris (Sudan, Egypt) P. hirsutus (Zimbabwe) P. mediospinosus (Cameroon, Nigeria) P. negligens (Zimbabwe, Malawi, Tanzania, Zambia) P. obscuripes (Malawi) P. pontifex (Tanzania) P. rapax (Zanzibar) P. rectangularis (Eritrea, Ethiopia) P. rex (Tanzania) P. ruepelli (Ethiopia) P. reuppelli (Eritrea) P. rufescens (Sierra Leone) P. rufihumeralis (South Africa) P. scalaris (South Africa) P. simpsoni (Ghana, Nigeria) P. subtilis (Congo) P. tewfiki (Egypt, Sudan) P. tewfikis (Sudan) P. transvaalensis (South Africa) P. trichozoans (Benin, Ghana, Guinea, Nigeria, Togo) P. ugandiensis (Uganda, Malawi) P. xanthotrichus (Gabon, Angola, Congo, Zimbabwe, South Africa) Now I just have to eliminate most of those! |

If i can find a key to the afrotropical Promachus species i will let you know. I think Londt could have written one.

Belated update: found Ricardo's 1920 paper on Promachus (Annals & Magazine of Natural History, series 9, vol 5), from which this should be P. xanthotrichus. Because of its date of publication, this does not rule out: P. aurulans (Tanzania); P. bomensis or P. subtilis (Congo); P. cinereus or P. hirsutus (both Zimbabwe); P rufihumeralis or P. transvaalensis (South Africa). Will update again one the original sources for these have been located... |
