Type material studied. Paratypes: 2 33, 4 ƤƤ, Republic of South Africa, KwaZulu-Natal Province, Nongoma District, Ngomi Forest ( RMCA).

Additional material studied. 13, 1Ƥ, Republic of South Africa, KwaZulu-Natal Province, Nongoma District, Ngome Forest, 27.49°S, 31.25°E, 27. i. 2008, indigenous forest, leg. R. Müller ( TMSA); 1Ƥ, same province but Tygerkloof, 27.51°S, 31.19°E, 28. x. 2002, grassland and forest, leg. TMSA staff ( TMSA).

Revised diagnosis. Male ( Fig. 3 View FIGURES 1 – 4 ) uniformly dark brown to nearly black; protrochanters ( Fig. 8 View FIGURES 7 – 8 ) with only slightly projecting apical part; profemora ( Fig. 8 View FIGURES 7 – 8 ) in lateral view with very shallow ventral subapical emargination and nearly straight dorsal margin; aedeagus ( Figs. 11, 12 View FIGURES 9 – 12 , 17–20 View FIGURES 13 – 20 , 23, 24 View FIGURES 21 – 24 ) in abparameral view with strong constriction between basal capsule and base of copulatory piece, long paramere rapidly narrowed in subapical region; in left lateral view long paramere distinctly narrowing towards apex, nearly straight and with long and narrow parameral tooth. Females ( Fig. 4 View FIGURES 1 – 4 ) pigmented as males, with moderately broad elytra ( Fig. 6 View FIGURES 5 – 6 ) and very distinct, sharply defined basal protuberance delimiting strongly elongated sub-basal impression, elytral suture in posterior half indistinctly raised, elytral apex in lateral view blunt.

Redescription. This species was adequately described by Leleup (1968), except for only general measurements and too simplified details of the diagnostically important aedeagus; only these details are given below.

Male ( Fig. 3 View FIGURES 1 – 4 ): BL 3.75–4.10 mm (mean 3.92 mm); HL 0.63–0.70 mm (mean 0.67 mm), HW 0.65–0.73 mm (mean 0.68 mm), AnL 5.16–5.30 mm (mean 5.23 mm), lengths of antennomeres (from I to XI): 0.95 mm, 0.53 mm, 0.45 mm, 0.37 mm, 0.45 mm, 0.45 mm, 0.47 mm, 0.45 mm, 0.38 mm, 0.35 mm, 0.37 mm; PL 1.03–1.13 mm (mean 1.07 mm), PW 0.78–0.83 mm (mean 0.79 mm); EL 2.08–2.28 mm (mean 2.18 mm), EW 1.33–1.43 mm (mean 1.38 mm), EI 1.57–1.60.

Aedeagus ( Figs. 11, 12 View FIGURES 9 – 12 , 17–20 View FIGURES 13 – 20 ) very slender, AeL 1.83 mm, in abparameral view weakly recurved; short paramere obliterated; long paramere rapidly narrowed in subapical region; parameral tooth long and narrow; apex of copulatory piece as in Figs. 23, 24 View FIGURES 21 – 24 .

Female ( Fig. 4 View FIGURES 1 – 4 ): BL 4.20–4.68 mm (mean 4.38 mm); HL 0.65–0.75 mm (mean 0.70 mm), HW 0.68–0.78 mm (mean 0.72 mm), AnL 4.50–4.72 mm (mean 4.60 mm), lengths of antennomeres (from I to XI): 0.93 mm, 0.5 mm, 0.4 mm, 0.37 mm, 0.38 mm, 0.35 mm, 0.40 mm, 0.35 mm, 0.33 mm, 0.27 mm, 0.32 mm; PL 1.03–1.18 mm (mean 1.09 mm), PW 0.78–0.88 mm (mean 0.82 mm); EL 2.50–2.75 mm (mean 2.60 mm), EW 1.55–1.78 mm (mean 1.66 mm), EI 1.54–1.63.
