Frankenbergerius opacus sp. n.
(Figures 4, 7, 10, 12, 43)
Holotype: „ (Figure 7). Body black, shiny, length 7.0 mm, width 4.1 mm. Dorsal surface with minute setae.
Head. Clypeus with anterior angles dentiform, separated by deep sinuation. Genae rounded, finely bordered. Genal sutures almost indistinct. Lateral margins of clypeus not sinuate near genal suture. Frontal suture indistinct on disc. Genae and anterior part of clypeus densely punctate, almost rugose; disc more sparsely punctate, margins of punctures indistinct.
Pronotum. Anterior and hind angles rounded. Lateral and anterior margins bordered, base not bordered. Border of anterior margin widened at middle, without sinuation. Dorsal surface densely and coarsely punctate; punctures almost adjacent. Base of pronotum concave (Figure 4).
Elytra. Striae distinct, punctate (punctures as wide as striae, separated by four to five puncture diameters on disc); striae 9 and 10 widely separated, with deeper and larger punctures medially. Intervals matt, impunctate, with rounded to elongated shiny tubercles.
Underside. Pygidium with strong border and small longitudinal keel, its disc deeply depressed and densely punctate (Figure 10). Mesosternum coarsely punctate; metasternum smooth on disc, otherwise punctate as mesosternum.
Legs. Anterior legs with three outer teeth with indistinct teeth between. Anterior tibial spur bifurcated.
Aedeagus. Parameres with widely rounded apices (Figure 12).
Paratypes: body length varies in males from 5.8 mm to 7.1 mm, width from 4.0 mm to 3.6 mm, in females 7.5– 6.1 mm and 4.6– 3.9 mm, otherwise variation among specimens is very weak.
The only recorded locality for this species is Stellenbosch (Western Cape Province) ( Figure 43 View Figures 39–43 ).
