Etymology.The specific name refers to the typelocality, noun in apposition.
Diagnosis.Males of K. buta sp. nov.are distinguished from the other species of the genus by the presence of a VTA on palp in addition to the RTA (VTA absent in K. ruwenzori sp. nov.and K. rutshuru sp. nov.) ( Figs 52A–C); females differ by the positioning ridges resembling a mustache ( Fig. 52D).
