“…Furthermore, we have provided evidence of the obligate feeding by larvae of Sepedonella nana Verbeke on small, freshwater oligochaetes (Vala et al, 2000a). The same observations were obtained with larvae of Sepedon (Mesosepedon) knutsoni (Vala et al, 2002). At present, these two species are the only true sciomyzids known to have strictly nonmalacophagous feeding behavior.…”

“…With regard to the Sciomyzidae of the Republic of Benin, we have previously recorded the collection and distribution of 8 species, with the description of Sepedon (Mesosepedon) knutsoni (Vala et al, 1994). We also have described the stages of development of Sepedon (Parasepedon) trichrooscelis Speiser, a parasitoid/predator of semi-terrestrial snails of the family Succineidae (Vala et al, 1995).…”

Predation by larvae of Sepedon ruficeps (Diptera: Sciomyzidae) and population dynamics of the adult flies and their freshwater prey. -The biology, phenology, and population dynamics of the adults of Sepedon ruficeps, the most widely distributed species of Sciomyzidae in Africa, were studied in Benin in permanent and temporary freshwater habitats. The feeding behavior of the larvae, expressed as the number of snails consumed, varies as a function of the species of prey utilized (Bulinus forskalii or Biomphalaria pfeifferi), as a function of the sizes of the predator/prey, and as a function of the stages of development of the larvae. In relation to the snail-prey, the second-and third instar-larvae show a food choice varying according to the specific ethology of the prey attacked. In all cases, the third-instar larvae always consume the largest number of snails and indifferently attack all of the species of snails utilized in laboratory rearings. The larvae consume, equally well, B. forskalii that are healthy or parasitized by the larvae of trematodes. Curiously, in laboratory rearings, in the absence of snails, the larvae of S. ruficeps are equally capable of attacking and developing at the expense of Aulophorus furcatus, a small, freshwater, oligochaete annelid (Naididae).

A review of the West African “snail-killing flies” or “marsh flies” (Sciomyzidae) shows that the fauna is not as dominated by the generally aquatic, predaceous genus Sepedon as was previously considered. Twenty species in seven genera, including three new species, Colobaea occidentalis, Pteromicra zariae and Sepedonella castanea are recorded. The Holarctic-Oriental genera Colobaea and Pteromicra are documented from Africa south of the Sahara for the first time. Biogeographical analyses based on the discovery of “Palaearctic” genera of Diptera south of the Sahara, faunal connections, and dispersal routes are presented. A key for identification and illustrations of diagnostic characters for some species are included.
