description: Key to the species of Spirostreptidae occurring in Namibia  1 Large species, 100–300 mm in length; collum with anterior corner strongly projecting; gonopod telocoxite without lateral conus (Fig. 47)........................................2  
 – Medium-sized species, <100 mm in length; anterior corner of collum not or only slightly projecting; gonopod telocoxite with lateral conus on median lamella (Figs 45, 50, lc).................................................................................................................4   
 2 Very large species, up to 300 mm in length, antennae reaching beyond 4 th segment; gonopod telocoxite lacking sclerotised spines, telopodite slender and trifid at apex (Figs 52, 56)............................................................................................................3   
 – Large species, about 175 mm in length, antennae reaching distal edge of collum; gonopod telocoxite with sclerotised spines on each distal corner; telopodite apically forked (Fig. 48)......................................... Doratogonus rugifrons (Attems, 1928)   
 3 Lateral lamella of gonopod telocoxite broadly rounded apically, without any distinct projections (Fig. 53, ll), femoral process of telopodite (Figs 52, 53, fp) straight to slightly curved...................................................... Spirostreptus heros Porat, 1872   
 – Lateral lamella of gonopod telocoxite apically projected and with triangular median lobe (Fig. 56, ll), femoral process of telopodite strongly curved (Fig. 56, fp).......................................................... Namibostreptus kymathorhabdus (Attems, 1914)   
 4 Metazonite broader than prozonite, posterior border of metazonites strongly striated (Fig. 60)............................... Synophryostreptus rugosostriatus (Schubart, 1966)   
– Metazonite and prozonite subequal, posterior border of metazonotites smooth or slightly undulated (Fig. 43), animal only striated to a maximum height of ozopores........................................................................................................................5  
 5 Pads on legs present and distinct; lateral conus of telocoxite short (Fig. 50, lc), solenomere with femoral process (Fig. 50, fp)....... Kartinikus australis Attems, 1914   
 – Pads on legs very small or absent; lateral conus of telocoxite long, solenomere with tarsal process (Fig. 46, tp) (Brevitibius)..................................................................6   
 6 55–57 segments, collum with 3 folds (Fig. 43); median lamella of telocoxite longer than lateral lamella (Figs 38, 39).......................................... B. oongongololo sp. n.   
 – 60 segments, collum with 1 fold; median lamella of telocoxite shorter than lateral lamella (Fig. 45).......................................................................... B. ondundu sp. n.
