Paratypes. 5♂♂, 24♀♀.

Remarks.

Described from one whole and six dissected males and numerous females (six dissected) from three proximate localities in the Cedarberg Mountains. All had the same distinct color pattern on the tegmina. The aedeagus was least typical for Hadroca, with the preatrium produced more and the shaft least curvate. This configuration approached that of Tzitzikamaia, but without apical processes. At present the aedeagi of species of Tzitzikamaia have single, apical paired processes. The six dissected aedeagi of H. treichroa sp. nov. do not show signs of damage at the apex which could suggest broken processes. The ventral curvature of the style apophysis corresponded well to that of the other Hadroca species. The ligulate female sternite VII was wider than long or almost square, with a recessed ligula similar to that of H. bualacauda sp. nov., and the submacropterous specimens of H. ramosa. However, the serration of the valvula 2 was least typical, i.e. with rectangular, close-set teeth. All other species of Hadroca have small teeth in the trough between larger, rounded teeth.
