Labiodental flaps exist in several African languages, and were first described by Doke (1931) in a study of Shona. Westermann and Ward (1933: 76) quote data from Tucker, who notes labiodental flaps in Kreish, a Central Sudanic language of the Sara-Bongo-Baguirmi group. In the same group of languages, Thomas (1981: 262) claims to find them in Bongo-Gberi and in Binga-Kara. Thomas defines these sounds as “vibrantes labiodentales” (see also Caprile 1981: 238). Hoffman (1963) and Ladefoged (1964) both identify these sounds in Margi. Cloarec-Heiss (1981: 225) reports such sounds in Banda, but describes them as “labiodentales lâches”, transcribed [ǔ]. Maddieson (1984) quotes two sounds of this type in the UPSID data base, one in Margi and the other in Gbeya.
