Caudoventral setae smooth and sharp-tipped.

Chelicera. Movable digit 25 long, with 3 teeth; fixed digit 23(22–23) long, with 5 teeth and a pilus dentilis.

Spermatheca. Calyx saccular, variable in different views, 16(12–18) long; atrium nodular, seemingly incorporated in calyx in particular views.

Etymology. This species is named after Hans Herren, first Director of Biological Control Center for Africa, Benin and one of the former Directors of International Institute of Tropical Agriculture (IITA), Benin Station, Cotonou.

Remarks. Kuzinellus febriculus differs from this species by having seta Z4 setiform and smooth, and 3 pairs of preanal setae (JV2 absent) on ventrianal shield. Kuzinellus niloticus , K. sennarensis and K. acanthus are also distinct from the new species by having seta j6 at least ca. 0.8 times (instead of ca. 0.3 times in this new species) as long as distance between its base and the base of J2. Kuzinellus relentus ( Denmark & Matthysse) differs from the new species by having calyx of spermatheca tubular, mostly slender, bulged near atrium and flaring near vesicle.

Blunt or knobbed Z5 and St IV were observed for individuals from different or the same localities. The specimen from 150 km SW Mpika is larger than the others and has concurrently the longest dorsal shield setae and macroseta of tarsus IV. Variation in the shape of the calyx of the spermatheca was observed between the right and the left side of some individuals, between individuals of given localities and between individuals of different localities.
