Type. ♂ holotype from Nigeria, Ibadan  , IITA [International Institute of Tropical Agriculture, 7 ° 29.4 ’N, 3 ° 53.4 ’E], fallow bush, 28.x. 1974 (A. Russell-Smith), in ZFMK (Ar 10248).

Other material examined. NIGERIA: Ibadan  , same locality as holotype, 22.iv. 1974 (A. Russell-Smith), 1 ♀ in ZFMK (Ar 10249); same locality, secondary forest, 17.iv. 1981 (A. Russell-Smith), 1 ♂ in ZFMK (Ar 10250); same locality, sweeping at road verges, 17.v. 1974 (A. Russell-Smith), 1 ♂ in BMNH.

Etymology. The name is a noun in apposition, derived from the type locality.

Diagnosis. Easily distinguished from known congeners by huge distal male cheliceral apophyses ( Figs. 364View FIGURES 359 – 371, 387View FIGURES 384 – 389), by distinctive shape of procursus ( Figs. 384–385View FIGURES 384 – 389), and by longer than wide epigynum with flat and deeply indented anterior plate ( Figs. 368View FIGURES 359 – 371, 389View FIGURES 384 – 389).

Male (holotype). Total body length 4.2, carapace width 1.6. Leg 1: 38.4 (9.0 + 0.5 + 9.3 + 18.0 + 1.6), tibia 2: 5.7, tibia 3: 4.1, tibia 4: 6.1; tibia 1 L/d: 70. Distance PME-PME 205 µm, diameter PME 140 µm, distance PME- ALE 55 µm, distance AME-AME 45 µm, diameter AME 135 µm. Carapace ochre-yellow with darker triangular mark posteriorly and lateral margins; ocular area ochre-yellow, clypeus with dark rim, sternum light brown; legs pale ochre-yellow, without darker rings; abdomen pale ochre-gray with barely visible darker pattern (specimen probably bleached). Habitus as in Figs. 365–367View FIGURES 359 – 371, ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’; clypeus unmodified except longer than usual hairs; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Figs. 364View FIGURES 359 – 371 and 387View FIGURES 384 – 389, with lateral proximal apophyses, small frontal projections, and distinctively exaggerated distal apophyses bent upwards at their tips, without modified hairs ( Fig. 388View FIGURES 384 – 389). Palps as in Figs. 369–371View FIGURES 359 – 371; coxa with distinct retrolateral projection weakly sclerotized; trochanter with ventral sclerotized rim but without projection; femur with whitish ventral area bordered retrolaterally by weakly sclerotized flap, without prolateral modification; prolateral femur-patella joint shifted toward ventrally (though not extremely); tarsus without stronger hairs; procursus with several distinctive processes ( Figs. 384–385View FIGURES 384 – 389; distal part appears hinged: Fig. 370View FIGURES 359 – 371); bulb with weakly sclerotized conical embolus ( Fig. 386View FIGURES 384 – 389). Legs without spines and curved hairs, with few vertical hairs (many hairs missing), retrolateral trichobothrium on tibia 1 at 1.5 %; prolateral trichobothrium present on all tibiae; pseudosegments barely visible. Gonopore apparently with two epiandrous spigots (not confirmed by SEM).

Variation. The other two males are bleached and in poor condition, with abdomens and tibiae 1 missing.

Female. In general similar to male; clypeus with shorter hairs. Tibia 1 missing. Epigynum longer than wide, with flat and deeply indented anterior plate and large posterior plate fitting into this indentation ( Fig. 368View FIGURES 359 – 371); internal genitalia as in Figs. 363View FIGURES 359 – 371 and 389View FIGURES 384 – 389.

Distribution. Known from type locality only ( Fig. 293View FIGURE 293).
