Abstract
A new species and a new genus of Rhachiberothidae, Rhachiella malawica gen. nov., spec. nov., are described from Malawi. The new species is characterized by a flat vertex, a long penisfilum in the male, and by a bifurcate pseudohypocauda in the female. This combination of characters requires the description of a new genus, which is the sister taxon of Mucroberotha Tjeder, 1959. This is the first record of Rhachiberothidae in Malawi.
The distributions of all 14 species of Rhachiberothidae so far known are shown in three maps.
