Etymology The name is a noun in apposition, meaning ʻknifeʼ in Latin and referring to the shape of the mesal acropodital process (map). Material studied (total: 5 ♂♂) Holotype TANZANIA: ♂, Dodoma Region, Mpwapwa District, Rubeho Mts (48 km W of Kilosa), Mangalisa Peak, 2100 m a.s.l., 26 Feb.1984, J. Kielland leg. (VMNH). Paratypes TANZANIA: 4 ♂♂, same collection data as for holotype (VMNH, ZMUC). Description (male) SIZE. Length up to 27 mm (smallers specimens incomplete), max. width 2.2–2.4 mm. COLOUR. After 33 years in alcohol uniformly yellowish, probably faded. ANTENNAE. Reaching back to middle of ring 4. BODY RINGS. Paranota absent, except for barely distinguishable keels on ring 2 (as in Fig. 4C). Stricture between pro- and metazonite smooth. A transverse row of setae on all rings. HYPOPROCT. Rounded-triangular, without distinct tubercles. LEGS. Length 1.2× body width. Relative lengths of podomeres: femur> prefemur> tarsus> tibia> postfemur. Scopulae on anterior legs on femur, postfemur, tibia and tarsus; those on femur missing from posterior legs, those on postfemur, tibia and tarsus present almost until end of body. STERNUM 5. An almost semicircular process between legs 4. STERNUM 6. Deeply excavated, rim simple. GONOPODS (Figs 8B, 24). Coxa with a short, triangular distolateral process (cxp); coxal lobe (cxl) small; prefemoral part (prf) ca 0.2× as long as acropodite; mesal acropodital process (map) large, simple, lamelloid, knife-like, gently curved, with basally parallel and apically converging margins, tip of process simple, sharp, dorsal and ventral margins of process without denticles; solenophore (sph) a rolled sheet, less than ⅔ × as long as map, forming a tube with three apical processes (Fig. 24C).
