Material. — Borneo, Sabah, Kata Kinabalu, in town park “Signal Hill ” 1 ♂. 6 ♀ in leaf litter, 24.vii.1979, 20+ 27.vii.1980 and 16.v.1991, P. R. and C. L. Deeleman . Malaysia, Subang, 1 ♂, palm oil plantation , on the ground, with 0. scrobiculata , 2.xii. 1990. C.L. Deeleman ; Penang Hill , 1 ♀, 100 m, 26.vi.1962, E.S. Ross and D.Q. Cavagnaro ( CAS) .

Diagnosis. — Very similar to scrobiculata in general appearance, distinguished from that species by leg colouring and characters in genital organs. The legs are lighter and more contrastingly coloured, patellae of all legs, most strikingly in leg I, lighter than tibia (in scrobiculata the patella and the tibia are homogenous pale brown); this may be used as character by which the species can be discriminated in the field. The apophysis of the male palpal tibia has a long retrolateral, vaguely undulating ridge without indention, the embolus is inserted proximo-medially rather than proximally as in scrobiculata and only one half coil long, the tegular apophysis is larger and more voluminous. The epigyne has thick-walled dark-coloured spermathecae and bursae juxtaposed near the epigastric fold, separated in the middle by a membranous zone.
