Pygofer lobe.

Apex broadly rounded, ventroposterior margin with medial and apical, membranous, disc-shaped structure. Sclerotized, short acuminate process on ventroposterior margin, orientation medioposteriad. Process sinuous, about 4 times longer than wide, with subapical ventral tooth, apices disjunct (Fig. 16H, K, N View Figure 16 ).

Subgenital plate.

Valvifer 2.

As in Fig. 13G View Figure 13 .

Valvula 2.

Apical half denticulate (Figs 13D, L View Figure 13 , 14D View Figure 14 ), with fine serration in trough between crests (Fig. 14B View Figure 14 ).

Valvula 3.

Etymology.

Named in Latin, adjective and noun in apposition, for the long, drawn out, tensus, spine on the shaft of the aedeagus (verpa). Gender Masculine.

Distribution.

Cedarberg, Clanwilliam, Doltuin, Halfmanshof, Fig. 18B View Figure 18 , red circle.

Discussion.

Flavorubivolatus tensiverpus is distinctly more red in the crown, pronotum and tegmina than yellowish color of F. glabriverpus . Measurements show that the crown length medially is slightly shorter, i.e. 0.4 mm and in the other species 0.4-0.5 mm. Genitalia in the male with aedeagal shaft linear to sublinear, position and orientation of basal processes (Fig. 16A-C View Figure 16 ), especially in Halfmanshof specimen, where the processes are more basal, slightly shorter and the apex of the shaft slightly wider than in the other species of this genus (Fig. 16B View Figure 16 , compare Fig. 16A, C View Figure 16 , Clanwilliam). Arms of the connective appear asymmetrical, but this is due to orientation during examination (Fig. 16F, G View Figure 16 ). The connective arms and medial arms of the styles are angled dorsad. Dissections included 8 males and 4 females and signs of parasites absent, i.e. no larva inside abdomen or pupal case. Plant records of Phylica oleifolia in Fig. 18D View Figure 18 . A record of Renosteria waverena from Halfmanshof, with same date as above, but with clear differences in male genitalia and color to that of F. tensiverpus .
