( Figs 57, 58, 60, 61, 63, 64 View FIGURES 57–65 )

Type material. Female lectotype and male allotype: South Africa, C.P., Grahamstown, June 1937, J. Hewitt [ NHMW] .

Diagnosis, female. Length 2.1–2.3 mm, 2.5 × as long as wide, colour black. Frons broadly, deeply concave from epistoma to vertex well above upper level of eyes, with longer setae near margins and shorter towards the centre; scapus with long dorsal spike with a long tuft of setae along the entire scapus, setae as long as the spike; antennal club setose with two strongly procurved sutures; scutellum with plumose scales; declivital interstriae 1 and 2 with few and small setae; interstrial setae on and near declivity short and broadly spatulate, confused, on disc with additional very long and narrowly spatulate setae; protibiae with three apical denticles. Male similar to female but declivity bears three pairs of sharp, curved spines on interstriae 2, 3 and 5, and antennal scapus rounded with short setae.

Distribution: South Africa.

New records. South Africa, East Cape, Grahamstown [GIS: -33.31, 26.57], June 1937 , J. Hewitt [ NHMUK]. Western Cape: Nature’s Valley [GIS: -33.965, 23.562], B. Jordal, leg., 9.xi.2006 GoogleMaps # 8, ex Cassine peragua ; Wilderness, Ebbe Flow [GIS: -33.980, 22.613], B. Jordal, leg., 31.x.2006 GoogleMaps , #2.

Biology. This species were previously reported from a variety of host plants, including Cape saffron, Cassine peragua (Celastraceae) and Cordia caffra (Boraginaceae) ( Schedl 1965). New collections were made from Cape saffron. Thin branches of 2–5 cm diameter were colonized by a male which was joined by either one or two females. Two broods of individual females contained 30 and 38 larvae, respectively.
