Material examined.

Type locality. Holotype male, South Africa, Eastern Cape province, Cradock, -32.166, 25.616, 19 Jan. 1984, J.G. Theron leg., sweeping, Asparagus sp., Asparagaceae CCDL28305, SANC, BMNH, INHS.

Type specimen.

Holotype male, glued to triangle card, pinned, with genitalia in microvial pinned to specimen. Original label "South Africa | Cradock | 19.i.1984 | J.G. Theron || Asparagus sp., Asparagaceae || SANC Pretoria | Database No. | CCDL28305".

Paratypes. 39♂♂, 29♀♀, total specimens 68.

Remarks.

The color pattern, especially of the head and tegmina, differentiated this species from the other species of Hadroca, although not always well developed. The face was also distinct. The male tergite X with the ventral paired process and the glabrous subgenital plate were unique. Least typical was the style with the compressed, laterally curved apophysis in dorsal view (Fig. 21M), and the apex with minimal ventral curvature in lateral view (Fig. 21N). The configuration of the aedeagus and its uniform sclerotization conforms to that of the species of Hadroca. It also appeared to be associated with wild asparagus. Modelled potential natural distribution is in Fig. 26E from eight records indicated by yellow squares.
