FEMALE. ( Specimens measured—Democratic Republic of Congo: 1; Nigeria: 1; Uganda: 1 and holotype). Idiosomal setal pattern: 12A:8A/JV-3:ZV .

Dorsum. Dorsal shield 290 (285–295) [295] long and 206 (200–215) [190] wide, striate anterior to J5 and reticulate between j6 and Z4. Apparently also with 5 pairs of solenostomes. Setae j1 26 (25–27), j3 43 (40–45) [48], j4 40 (37–41) [44], j5 40 (36–44) [43], j6 55 (50–59) [57], J2 53 (50–55) [56], J5 10 [9], z2 24 (23–25) [23], z3 51 (50–51) [53], z4 56 (54–57) [58], z5 38 (35–40) [38], Z4 63 (62–64) [62], Z5 64 (63–66) [63], s4 61 (60–62) [63], s6 65 (65–66) [67], S2 69 (68–71) [71], S4 70 (70–71) [71], S5 22 (19–24) [17], r3 40 (38– 43) [44], R1 59 (58–60) [60]. Setae serrate and knobbed, except for j1, z2, S5 and r3, sharp-tipped; and J5, smooth and sharp-tipped. Most setae longer than distances between their bases and bases of setae following next behind.

Peritreme. Extending to level between j1 and j3.

Venter. Sternal shield mostly smooth, with few lateral striae and 2 pairs of setae (ST3 on integument); posterior margin indistinct; distances between ST1–ST3 55 (52–57) [59], ST2–ST2 55 (54–56) [50]. Genital shield smooth; distance between ST5–ST5 55 (53–57) [55]. Ventrianal shield reticulate, subtriangular, with anterior margin convex, 102 (98–104) [97] long, 89 (84–96) [85] wide at level of ZV2, with 3 pairs of preanal setae (seta JV3 absent); round pre-anal pores posterior to and vertically aligned with JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth and sharp-tipped, except JV5, serrate and knobbed.

Chelicera. Movable digit 27 long, with 1 tooth; fixed digit 24 long, with 2 teeth.

Spermatheca. Calyx variable in shape (see remarks), 14 (11–17) long; atrium small, sometime incorporated in calyx.

Legs. Macrosetae knobbed: Sge III 22 (21–22) [20], Sti III 18 (17–19) [19], Sge IV 32 (31–32) [32], Sti IV 22 (21–24) [23], St IV 40 (37–42) [43]. Chaetotaxy: genu II: 2-2/0, 2/0- 1; genu III: 1-2/1, 2/0-1.

Specimens examined. Democratic Republic of Congo: 1 female, 34 km E Matadi, Bas-Congo, on Andropogon guayanus , 11-VII-1991, A. Onzo. Nigeria: 1 female, 1 km S Odukpan, on Elaeis guineensis , 16- IV-1992, A. Onzo. Uganda: Holotype female was collected, near Kampala, in nest of social spider, 1957, G.O. Evans; one female, 25 km N Bundibugyo, on E. guineensis , 9-X-1990, J.S. Yaninek.

Remarks. The spermatheca was not illustrated or described in the original description of this species. One of the authors (GJM) examined the female collected from Ibadan, Nigeria, on Musa sp. by Matthysse & Den- mark (1981) and reported as Clavidromus hartlandrowei , and illustrated its spermatheca ( Fig. 24E ); the calyx is distally bell-shaped on ca. 40% and distally slender on 60% of its length; the atrium is undifferentiated. The calyx of a specimen recently collected from Uganda is similar to that of the female reported from Nigeria by Matthysse & Denmark (1981). However, in the specimen from Nigeria, collected during the recent surveys, the proximal half of the calyx is bell-shaped and the distal half constricted (constricted portion not distinct) ( Fig. 24C ). The specimen from the Democratic Republic of Congo has the calyx of the spermatheca saccular ( Fig. 24D ). The latter 2 specimens have the atrium distinct and small.

World distribution. Democratic Republic of Congo, Nigeria and Uganda.
