( Figs 65 View FIGURES 51–77 , 92 View FIGURES 78–104 , 119 View FIGURES 105–130 , 144 View FIGURES 131–156 , 169 View FIGURES 157–179 , 194 View FIGURES 180–205 , 220 View FIGURES 206–232 , 246 View FIGURES 233–258 , 265 View FIGURES 259–273 )

Diagnosis. Aedeagal shaft long, tubular, not twisted and deflected left. Style with apophysis projecting beyond plate apex. Plate without dorsal tooth.

Etymology. Latin, suffix, - ensis, denoting place, maloti, Sesotho word referring to the Drakensberg mountain range of KwaZulu-Natal.

Dimensions. Male (n = 6). Lengths: apex of vertex to apex of tegmina 3.5–3.7 mm, apex of vertex to apex of abdomen 2.9–3.5 mm; vertex medially 0.4–0.5 mm; vertex laterally next to eye 0.3 mm; pronotum medially 0.3–0.4 mm; scutellum medially 0.3–0.6 mm. Maximum widths: head 1.0– 1.1 mm; pronotum 0.8–0.9 mm; scutellum 0.4–0.5 mm. Ocellus: diameter 28 µm; ocellocular distance 50–59 µm.

Abdominal apodemes. Male. Fig. 265 View FIGURES 259–273 .

Genital capsule. Male. Aedeagal shaft tubular, tapering at apex; long, 1.8 times as long as dorsal apodeme, dorsal apodeme biramous; gonopore ventral ( Figs 65 View FIGURES 51–77 , 92 View FIGURES 78–104 ). Connective as in Fig. 119 View FIGURES 105–130 . Plate posterior margin truncate; medial angle obtuse; 5–7 uniseriate setae ( Fig. 144 View FIGURES 131–156 ). Pygofer lobe broadly rounded ( Figs 169 View FIGURES 157–179 , 194 View FIGURES 180–205 ). Style apophysis with wide base, tapering; reaching beyond apex of plate, visible in situ; apophysis as long as median arm ( Fig. 220 View FIGURES 206–232 ).

Dimensions. Female (n = 4). Lengths: apex of vertex to apex of tegmina 3.5–3.9 mm, apex of vertex to apex of abdomen 3.0–4.0 mm; vertex medially 0.4–0.5 mm; vertex laterally next to eye 0.3–0.4 mm; pronotum medially 0.4–0.5 mm; scutellum medially 0.3–0.4 mm. Maximum widths: head 1.0– 1.1 mm; pronotum 0.8–0.9 mm; scutellum 0.4–0.5 mm. Ocellus: diameter 28 µm; ocellocular distance 50–59 µm.

Genital capsule. Female. Sternite VII with shallow, wide V-shaped notch, moderately sclerotized, rectangular, 0–1 pairs of pillars ( Fig. 246 View FIGURES 233–258 ). Third valvula with apex with three pairs robust macrosetae (length 23.2–32.2 µm, basal width 3.4–6.4 µm); subapical 3 pairs with narrow macrosetae (length 31.0–33.5 µm, basal width 1.3–2.6 µm), proximal setae less than half as long. Second valvula serrate.

Material examined. Holotype male. South Africa, KwaZulu-Natal. Sani Pass, 29°35ʹS 28°18ʹE, 2520 m, 20.iv.2002, M. Stiller, E. Breytenbach, DVac Aristida monticola   ( Poaceae   ) ( SANC). Paratypes (12♂, 4♀, 3 nymphs). KwaZulu-Natal. 8♂, 4♀, 3 nymphs, ibid. holotype; 4♂, Orange River Catchment, 28°53ʹ40.22ʺS 29°01ʹ08.25ʺE, 2880 m, 16.iv.2006, M. Stiller sweeping grass & forbs ( BMNH, SANC).

Remarks. Undissected specimens can be recognized by the apophysis of the style that projects beyond the apex of the plate and the absence of a dorsal tooth on the apical margin of the plate. A number of other species, however have a similar sternite VII. They are E. denticulatus   , E. eccentricus   and E. tubulus   . The latter two species have different distributions, but E. denticulatus   has been recorded from the Drakensberg.
