Figs 5, 12A, 13 Agelena leucopyga kiboschensis Lessert, 1915: 487. Agelena kiboschensis Roewer, 1955: 41. Type material. Agelena leucopyga kiboschensis , Tanzania, Kiboscho, 3000-4000 m, (type ♀, no date), Kibonoto, (1 ♂, type, X), 1915, Lessert, Museum d'histoire naturelle de Geneve , Switzerland(not examined). Other material examined. Rwanda, 2♀, 1953, Coll. C.F. Roewer (SMF 9907841; 9907951). Diagnosis. M. kiboschensis comb. nov. can be distinguished from M. leucopyga by the larger copulatory ducts (Fig. 5B) compared to reduced ones in the latter (see fig. 4 in Santos and van Harten 2007 ). It can also be separated by the missing white spot posteriorly on the dorsal side of the abdomen (Fig. 12A) which is present in M. leucopyga (see fig. 5a in Roewer 1955 ). This species can also be separated from M. moschiensis comb. nov. by the shape of the median lobe which is small and round in M. kiboschensis comb. nov. (Fig. 5B) compared to larger and ovoid in M. moschiensis comb. nov. (Fig. 7B). The copulatory duct originates posteriorly and is projected centrally in M. kiboschensis comb. nov. (Fig. 5B) compared to central origin and anteriorly projected in M. moschiensis comb. nov. (Fig. 7B). Redescription. Female. Total body length 12.82. Carapace 5.77 long, 4.17 wide.
