Type material examined: Holotype: ♂ ‘ S. Afr., Tvl. Nelshoogte Knuckles rocks for, 25.47S, 30.50E, 8.12.1986, E-Y: 2357 UV light collection, leg. Endrödy-Younga’ ( TMSA) GoogleMaps . Paratypes: 1 ♂ ‘ S. Afr., Tvl. Nelshoogte Forest station , 25.50S, 30.50E,/ 2.12.1986, E-Y: 2346 UV GoogleMaps light collection, leg. Endrödy-Younga’ ( ZFMK) .

Diagnostic description: Body length: 9.6 mm, elytral length: 6.1 mm, maximum width: 5.1 mm. Labroclypeus wide and short; not incised or narrowed behind labrum. Anterior margin of labroclypeus medially weakly sinuate. Angle between lateral margin of labroclypeus and ocular canthus indistinct. Eyes, ratio diameter/ interocular width: 0.59. Antennal club slightly longer than remaining antennomeres combined. Mentum convexly elevated and slightly flattened anteriorly. Basal marginal line of pronotum widely absent. Marginal line of anterior margin of pronotum medially widely interrupted. Hind wings fully developed. Epipleural edge complete over entire elytral length. Metasternum and metepisernites in length normal. Ratio of length of metepisternum/metacoxa: 1/1.36. Metacoxa glabrous except a few fine lateral setae; its anterior marginal line complete. Protibia, externally tridentate; external margin between apical two teeth moderately sinuated. Metatibia, ratio of width/length: 1/3.86. Basal group of dorsal spines of metatibia at first-third of metatibial length; apical group of external spines at two-thirds of metatibial length. Apex of metatibia interiorly near tarsal articulation not sinuate or truncate; apical face simple, not elevated or produced. Meso- and metatarsomeres dorsally punctate. Mesotarsomere 1 slightly longer than the subsequent tarsomere. Aedeagus and habitus: Fig. 4H. Female unknown.

Etymology: The new species is named in reference to its asymmetric dorsomedian lobe of the male phallobase.

Variation: Body length: 9.0– 9.6 mm, elytral length: 6.1–6.2 mm, maximum width: 4.6–5.1 mm.
