Recent studies have indicated that frequent anthropogenic disturbances in tropical developing countries are primary drivers of reduction in community diversity and local extinction of many arthropods, including dragonflies. We assessed the impact of anthropogenic disturbances on odonate assemblages across three different land use types, in a biodiverse nature reserve in Ghana. A total of 37…
Problems in Chlorocypha classification: four cases from West Africa and a discussion of the taxonomic pitfalls (Odonata: Chlorocyphidae)
The taxonomy of Chlorocypha species is problematic due to variability and the paucity of morphological characters. Subspecies radix of C. glauca is raised to specific rank. C. sharpae is found to be a synonym of C. luminosa. The synonymy of C. jejuna with C. luminosa is rejected. The former species is similar to the Southern…
The identity of the West African zygopterans Pseudagrion emarginatum and P. camerunense (Odonata: Coenagrionidae)
Pseudagrion emarginatum is removed from the synonymy of P. melanicterum. The following synonymies are established: P. coeruleiceps of P. emarginatum and P. angelicum of P. camerunense. The latter, formerly known as Enallagma camerunense, should be removed from the list of threatened African Odonata.
