Genus Brevitibius Attems, 1950

Brevitibius: Attems 1950: 249 , fig. 93; Demange 1970: 394; Krabbe 1982: 131; Hamer 1999: 10.

Type species: Spirostreptus angolanus Attems, 1934 , by original designation.

Diagnosis: Ozopores from the 6 th segment onwards. Prozonites with punctures, metazonites with distinct striae below ozopores. Limbus smooth. Sternites striated. Legs with much reduced pads ( Fig. 40), hypoproct surface porous; with fold(s) and rows of punctures on collum. Gonopod aperture open distally, segments not fused ventrally ( Fig. 41).

Gonopod telopodite with tibial process originating distad of femoral knee ( Figs 38, 39, 46, tp), its tip covered in fold of tibiotarsus, which is wrinkled at the outer side; tip of solenomere acute, with two small folds before end of seminal duct; lateral lamella with lateral conus ( Figs 44, 45, lc).

Remarks: Brevitibius is a small genus, containing only two species: B. angolanus (Attems, 1934) and B. obtusus Kraus, 1958 , both known from Angola. Krabbe (1982) described a species from Tanzania, which she tentatively placed in this genus as Brevitibius (?) bulbiferans.

Attems (1950) erected the genus based on the abruptly shortened tibial part of the telopodite, the anteriorly directed gonocoel and the large lateral conus (which is missing in B. obtusus ).
