Material examined
Four female and two male specimens with data: South Africa, EC, Hogsback, 1300 m, 7 Sep 2014, R. Perissinotto & L. Clennell leg. (TMSA, ISAM, KAPC, RPPC). Only one male and one female were found still alive, while the other four specimens were already dead, two with soft tissue consumed by spiders.
Description
♀. Length: 10–11.5 mm; width: 3.5–4 mm (n = 4). General habitus as in male (Figure 2), but with shorter antennae and legs and wider elytra (Figures 1–3).
Coloration. Dark greyish brown, apices of the elytra slightly lighter brown. Palpi, antennae, legs and ventral side light yellow brown. Mandibles light yellow brown, with the exception of the apices which are black.
Body surface. Whole surface covered in short depressed silky tomentum. Long, thin, hairlike whitish grey bristles present especially on the lateral side of the mandibles, scapus and pronotal sides (Figure 1A). Head. Broad with strong, falciform mandibles. Palpi moderately long, terminal segment only very weakly enlarged. Eyes coarsely facetted, strongly protuberant and broadly separated, small, oblique, not emarginate and far behind antennal tubercles. Frons between the eyes broad and flat. Antennae reaching to the second half of the elytra. Antennomeres becoming shorter towards the end, but not very different in length from each other.
Pronotum. As long as wide with long, rather acute lateral spines pointed strongly obliquely upwards (Figure 1A). Surface like in male (Figure 2). Disc convex in the middle. Unlike in male, the anterior edge is not broader than the posterior. Scutellum. Very small, hardly visible, wider than long.
Elytra. Fused, somewhat broader than in male, widest in the anterior third. Strongly convex, both laterally and dorsally. Slightly over half of the anterior part sparsely punctate. Apices broadly rounded.
Legs. Long and slender, but shorter than in male (Figures 2 and 3). Coxae large and projecting (Figure 1B). Ventral surface. All coxae well separated from each other, especially the metacoxae. The first visible abdominal sternite is the longest, with the following becoming progressively shorter until the fifth visible (Figure 1B).
Male. A general description is provided in Adlbauer (2008)[1]. Only further details of the genitalia, along with photos of whole genitalia as well as tegmen and aedeagus separately are provided here (Figure 4A–C). Aedeagus with heavily sclerotized acute dorsal lobe bearing an acuminate apex. Ventral lobe with a rounded, weakly truncate apex, much shorter than dorsal lobe, and decidedly less sclerotized. Apophyses long, strap-shaped and constituting more than 50% of total aedeagus length (Figure 4B). Tegmen with relatively long and slender, slightly diverging parameres with apical brushes of very long setae (Figures 4A, C). Presence of sheath-like appendage between the base of the parameres and the “tegmen ring”, on both sides.When the aedeagus is in its position inside the tegmen, the apex of the dorsal lobe reaches almost to the apices of the parameres, while the ventral lobe reaches just beyond the point of diversion of the parameres (Figure 4A).
