An annotated list of Odonata collected in Ghana in 1997, a checklist of Ghana Odonata, and comments on West African odonate biodiversity and biogeography

Collections were made at 8 localities in southern Ghana during the summer of 1997. Three regions were sampled: coastal savanna, wooded savanna, and rainforest. 71 spp. were collected, 24 of which are new for the country, bringing the Ghana list to 123 spp. A list of spp. known from the country is included. Trithemis dejouxi Pinhey, 1978, is raised to specific rank. Individual variation in Phaon iridipennis and Palpopleura lucia is quantified. West African Odonata biodiversity and biogeography are discussed.
