Diagnosis

This species can be distinguished by elytral interval 8 with a long carina occupying twothirds of the length of the elytron and by its small body size.

Description

Black to dark brown, shiny beetle ( Figure 39 View Figures 39–43 ). Body length of males 4.6–7.2 mm, width 2.5–3.2 mm, of females 4–7.3 mm and 2.4–3.9 mm. Dorsal surface with minute setae which may be abraded on most surfaces.

Head. Clypeus with two horn-like processes; processes slightly longer in males ( Figures 41, 42 View Figures 39–43 ). Genae obtuse, finely bordered. Genal sutures distinct. Lateral margin of clypeus with deep sinuation near genal suture. Frontal suture obsolete medially. Dorsal surface of horn-like processes granular, rest of head densely punctate except for middle area of clypeus which is smooth. Eyes small, almost completely divided by canthus, their dorsal parts slit-shaped.

Pronotum. Pronotum narrower in anterior part, 1.6 times wider than long. Anterior margin not sinuate medially, or with minute unclear sinuation. Lateral margins and anterior angles finely bordered, anterior margin and base not bordered. Surface coarsely punctate with more or less elongated punctures.

Elytra. Striae distinct, punctate (punctures separated by three to four puncture diameters). Intervals indistinctly punctate on disc, with elongated tubercles. Interval 8 with long carina occupying two-thirds of elytron.

Underside. Pygidium with deep border, its disc densely punctate. Abdominal and thoracic sternites coarsely punctate except for disc of metasternum.

Legs. Anterior tibiae with smaller teeth between major outer teeth in most specimens. Spur of anterior tibia bifurcated in males and simple, acute in females.

Aedeagus. Parameres with angulate apices in lateral view ( Figure 40 View Figures 39–43 ).

Variability. Except for body size, the specimens examined show very little variation. Females differ from males in not having bifurcated spur of anterior tibiae and clypeus with somewhat shorter processes with smaller sinuation between ( Figures 41, 42 View Figures 39–43 ).

Distribution

This species is known from a number of localities in Limpopo, Mpumalanga, and KwaZulu-Natal provinces.
