This study infers a phylogenetic hypothesis for the family Hersiliidae from the Afrotropical Region. A new genus is proposed, Prima gen. n., to include P. ansiae sp. n. from Madagascar. The first record of the genus Murricia Simon from the Afrotropical Region is presented, with the description of a new species, Murricia uva sp. n. from Central Africa. The species level phylogenetic analysis comprises 43 taxa, of which 27 are Afrotropical hersiliids with both sexes known, 13 species non-Afrotropical and three outgroup species; 66 characters were scored. The analysis resulted in 56 most parsimonious trees. The preferred tree supports the monophyly of Tyrotama Foord & Dippenaar-Schoeman, 2005, and retrieves it as the sister-group of Hersiliola Thorell, 1870. These two genera form the most basal lineage of the family Hersiliidae. Tama Simon, 1882, is the sister-group of all the remaining hersiliids, again divided in two large lineages. The first of these clades comprises all arboreal hersiliids without biarticulations on the metatarsi I, II and III. Neotama is basal in this clade and the new genus Prima part of its sister-group (Neotama (Tamopsis (Prima (Ypypuera (Iviraiva + Yabisi))))). The second clade consists of two sister clades viz. Hersilia, whose monophyly is confirmed, and the genus Murricia. The family Hersiliidae now includes six genera in the Afrotropical Region, viz. Hersilia, Hersiliola, Murricia, Neotama, Tyrotama Foord & Dippenaar-Schoeman, 2005, and Prima n.gen. A key to the Afrotropical genera is provided.
