Remarks. The original description was based on a single female specimen from Kirstenbosch in the Western Cape. There is no illustration of the spermatheca, and due to there being no male specimen, there is also no illustration of the male genitalia. Being able to examine additional material of the species has allowed me to complete the missing data for this species:

Body length: 2.38–3.07 mm.

Male genitalia. Ventral aspect of the penis ( Fig. 6 ) broadest at the base, tapering slightly anteriad, with concave sided and regularly subtriangular apex; lateral aspect curved, broadest in anterior third, tapering abruptly towards the apex.

Female genitalia. Spermatheca ( Fig. 7 ) with a slender curved cornu; slender corpus; subsquared ramus; and slender nodulus which tapers distinctly apicad. Gonocoxites elongate, tapering evenly apicad, obtuse apically with long slender styli bearing setae. Sternite VIII with umbrella-shaped translucent plate; apodeme about 1.5× longer than plate, broadest at mid-length, terminating near apical part of plate.
