Diagnosis

The males of Afroneutria quadrimaculata sp. nov. differ from those of the other species of the genus by the laminar embolus with enlarged tip and the curved, subdistal, additional projection of the embolus ( Figs 9 View Fig. 9 A, 15 View Fig. 15 A). The females can be distinguished by the large and elongated lateral projections of the epigynum and the curved dorsal spermathecae in the vulva ( Figs 9 View Fig. 9 D–E, 12 B).

Etymology

The specific name is derived from Latin, quadri- (four) and macula- (spot), meaning to have four spots and making reference to the four white spots on the venter of the abdomen.
