Tsetse flies compose a family of their own, Glossinidae, which is placed within the Hippoboscoidea due to the morphological and reproductive similarities of tsetse flies to keds and other hippoboscid flies (McAlpine, 1989). Glossinidae includes the single genus Glossina with 23 species, 6 of which are further divided into 14 subspecies (Gouteux, 1987; Potts, 1973). Glossina (‘tongue fly’, in reference to the prominent proboscis) species are arranged in three subgenera – Austenina, Nemorhina, and Glossina – that correspond roughly with groups of species found in different ecological settings. The subgenera often are cited by their group names: the fusca group (Austenina), the palpalis group (Nemorhina), and the morsitans group (Glossina).
