Recognition. ( Fig. 1 ). Dorsocentral setae 2+4; lower proepimeral seta upwards directed; prosternum bare; prealar seta absent; anepimeron bare; katepisternal setae in C. annulitarsis 0+1 and katepisternum with many cilia on disc ( Fig. 2 ); tibiae often partly creamy-white ( Fig. 3 ); male: mid leg modified ( Fig. 12 of Emden 1951: 379), the femur (except in C. pallipes ) on apical third with an anterior notch with some strong setae on margin ( Fig. 4 ), first tarsomere curved ventrally and with some stiff setulae ( Fig. 4 ); halter pale; frons with only one pair of inclinate frontal setae, which are strong; female frons without interfrontal or proclinate orbital setae. Five species: Burundi, Kenya, Rwanda, South Africa, Tanzania, Uganda, Zaire ( Emden 1951, Couri 2007, modified).

Notes: The genus can be easily segregated using the keys provided by Emden (1951: 379–380) and Couri (2007) for Afrotropical Muscidae genera. In the current classification of Muscidae , the genus falls in the tribe Limnophorini of the Coenosiinae .

Camptotarsopoda was added to the datamatrix of the cladistic analysis of Couri & de Carvalho (2003) and a new analysis was carried out under the same parameters. The new analysis placed Camptotarsopoda within the Limnophorini based on the absence of the prealar seta, absence of calcar and the short anal vein, corroborating the position previously suggested by Stein (1913).

The medium sized ovipositor with large and developed tergites and relatively short hypandrium and cerci, the bare prosternum, the developed labellum, among other characters bring Camptotarsopoda closer to the general structure of the Limnophorini , where the derivate characters present in other genera are missing.

The five species can be segregated using Emden’s key (1951).
