Identification key to Central African pholcid genera

References to figures in upper case (“Fig.”) refer to illustrations herein; figures in lower case (“fig.”) have been published previously and are freely accessible online (at http://www. pholcidae .de/). Artema atlanta Walckenaer, 1837 is included as it probably occurs in Central Africa, even though we know of no records.
