• Twelve genera are excluded from the sub-Saharan Africa checklist based on evidence from literature or re-identification. Atractylocarpus, Chorisodontium, Ctenidium, Dicranodontium, Homalia, Isothecium, Lasiodontium, Meesia and Potamium are excluded as the collections belong to other genera, and Camptochaete, Phyllodrepanium and Ptychomnion are excluded because of evidence of mistaken (or no longer existing) localities. As a consequence, the following families no longer are known from Africa: Echinodiaceae, Lembophyllaceae, Phyllodrepaniaceae and Ptychomniaceae. Ectropothecium nishimurii O’Shea & Ochyra, nom. nov. replaces Ectropothecium mauritianum (Broth.) Nishimura, hom. illeg., and Kindbergia kenyae (Dixon ex Tosco & Piovano) O’Shea & Ochyra, comb. nov. replaces Isothecium kenyae Dixon ex Tosco & Piovano. Lasiodontium mieheanum Ochyra in S. Miehe & G. Miehe, nom. nud., is a synonym of Daltonia angustifolia Dozy & Molk. and accordingly Lasiodontium Ochyra in S. Miehe & G. Miehe, nom. nud., must be placed in synonymy with Daltonia Hook. & Taylor.
