Abstract
The species richness of the frugivorous fruit fly fauna of western African (in particular of Ivory Coast, Ghana, Togo, Benin and Nigeria) is discussed. The diversity is compared at a national level and between the ecoregions within the national boundaries of the study area. A new species, Dacus goergeni sp. nov. is described and additional taxonomic notes are presented.
Highlights
Tephritidae are picture-winged flies of variable size and worldwide distribution
True frugivorous tephritids mainly belong to the Dacini and include the genera Bactrocera Macquart, Dacus Fabricius (Dacina), Ceratitis McLeay, Capparimyia Bezzi, Carpophthoromyia Austen, Neoceratitis Hendel, Perilampsis Bezzi and Trirhithrum Bezzi (Ceratitidina) (Thompson 1999), several of which are of agricultural importance as pests of commercial fruits and vegetables (White & Elson-Harris 1994)
The total number of species found in the study area was 117 (Table 1), which is about 30 % of all known Dacina and Ceratitidina species in the Afrotropical region
Summary
Tephritidae are picture-winged flies of variable size and worldwide distribution. commonly named ‘fruit flies’, the larvae of some species develop in other parts of the host plant, including flowers, seeds and stems (White & Elson-Harris 1994).
