Setae j1, j3, z3, Z4, Z5, s4, s6 and r3 thick, generally long, strongly serrate; other setae short or minute and smooth. Setae Z4, Z5, s4, s6 and r3 inserted on tubercles and divided longitudinally.

Peritreme. Extending almost anterior to setae j1.

Venter. Sternal shield not sufficiently distinct to be illustrated and described; distances between St1–St3 55(54–56), St2–St2 60(60–61). Genital shield smooth; distance between St5–St5 61(60–61). Ventrianal shield vase-shaped, smooth, anterior margin slightly convex, 92(88–97) long, 36(35–37) wide at level of Zv2 and 47(45–48) wide at level of anus; preanal pores posterolaterad of Jv2. Caudoventral setae smooth, except Jv5, thick and strongly serrate.

Chelicera. Movable digit 24 long, with 1 tooth; fixed digit 22 long, with 3 teeth and a pilus dentilis.

Spermatheca. Calyx bell-shaped, 25 long [often only the more sclerotized part near the atrium visible, 3(2–3) long]; atrium small and nodular.

Specimens examined. Four females, Burundi: ISABU Research Station , Bujumbura, on unknown plant, 11-XII-1989, J.S. Yaninek .

Remarks. The absence of setae J2 and R 1 in this species places it in the horridus species group ( Denmark 1966; Chant & McMurtry 1994).
