TYPE: Male holotype taken in pitfall trap in fallow bush plot at the International Institute of Tropical Agriculture, Ibadan, Oyo, Nigeria (Nov. 1974; A. Russell-Smith), deposited in MRAC (177439, PBI_OON 9629) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Members of this species can easily be distinguished from all their congeners by the highly patterned legs (fig. 129).

MALE (PBI_OON 9629, figs. 81–107, 126–128): Total length 1.32. Carapace brown, sides smooth, with indistinct longitudinal dark stripe, extending from opposite coxae II to opposite coxae IV; dark longitudinal stripe present along midline. ALE, PLE subequal, larger than PME; ALE separated by their radius to diameter; posterior eye row procurved from front. Sternum, chelicerae yellow. Labium, endites dark red-brown. Endites medially with protuberances over sides of labium, distally elaborate. Dorsal scutum brown, covering most of abdomen length, more than half of abdomen width. Postepigastric scutum yellow, short, almost rectangular, covering about 1/3 of abdomen length. Legs with femora, basal portions of tibiae, patellae darkened. Leg spination: patellae: I v0-1p-1r; II v0-0-1p; tibiae: I v2-4-0; II v1p-1p-0; IV v0-0-2. Palp with proximal segments yellow-brown; cymbium yellow; bulb yellow; embolus simple, straight process.

FEMALE (PBI_OON 32995, figs. 108–125, 129–134): Total length 1.28. Labium and endites yellow. Postepigastric scutum without posteriorly directed lateral apodemes. Leg spination: patellae: I v0-1p-1r; II v0-0-1p; tibiae: I v2-4-0; II v2-2-0; IV v0-0-2. Posterior receptaculum with triangular posterior invagination, anterior receptaculum elaborate.
