The specific name refers to the type locality, 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 52 A–C); females differ by the positioning ridges resembling a mustache ( Fig. 52D ). FIGURE 52 . Kikongo buta sp. nov. Male palp: (A) prolateral view; (B) ventral view; (C) retrolateral view. Female: (D) epigyne, ventral view; (E) vulva, dorsal view; (F) vulva, schematic course of internal duct system. C—conductor; CD—copula-tory duct; CO—copulatory opening; CoD—connecting duct; E—embolus; FD—fertilization duct; PS—primary spermathecae; SS—secondary spermathecae; RTA—retrolateral tibial apophisys; VTA—ventral tibial apophisys. Scale bars: 0.5 mm. FIGURE 53. Known distribution records of species of Kikongo gen. nov. from D.R. Congo and Kenya. Description. Male ( holotype ). Total length: 2.32.
