Type locality. Armmanshoek, Richtersveld NP, 28.41756°S 17.07902°E.
Type material. Holotype: ♂ ( TMSA): “Armmanshoek / Richtersveld NP / S28.41756° E17.07902° / 13.iv.2005 / 623 m / C. Deschodt & A. Deschodt [printed] // HOLOTYPE / Macroderes oreatus / Abdalla & Deschodt / 2018 [red label, printed]” GoogleMaps ; Paratypes: 5 ♀ f #, same data as holotype GoogleMaps , 1♀ ( TMSA) , 2♀♀ ( UPSA) , 2♀♀ ( SANC) .
Holotype description. Holotype, ♂ ( Fig. 19 View FIGURES 19–23 ). Body length 7.2 mm, width 4.9 mm. Specimen is teneral.
Head. Genae right-angled. Frontal suture very distinct, curving slightly, no tubercle. Genal sutures barely discernible. Dorsal surface of clypeus behind frontal suture punctate punctures small, irregular and separated by 1– 3 puncture diameters, gradually becoming rugose proximally.
Pronotum. Convex, lateral margins round. Anterior lateral angles almost right-angled, posterior lateral angles rounded. No excavation anterolaterally. Lateral border not punctate. Dorsal surface shagreened to matte, with regular punctures separated by 1–2 puncture diameters ( Figs. 78 View FIGURES 76–81 , 86 View FIGURES 82–87 ).
Elytra. Elytral interstriae 1–8 even, shagreened, irregularly punctate, punctures irregularly sized, separated by 0.5–2 puncture diameters, margins of punctures not carinate ( Fig. 96 View FIGURES 94–99 ). Striae punctate with punctures separated by 2–4 puncture diameters. Sutural interstria narrow with single row of punctures up to apex, all other elytral interstriae wider, with 2–3 very irregular rows of punctures. Stria 9 long, 3/4 the length of elytron; interstria 10 is 2–3 times narrower than interstria 9 in the middle of elytron.
Aedeagus. Sclerite of the internal sac straight, with weakly developed lateral process. ( Fig. 36 View FIGURES 24–39 )
Size range. Females length: 7.0– 7.2 mm; width: 4.5–4.9 mm.
Female. Female differs from male by having less developed frontal suture as well as the elytral striae 1–8 being less shagreened and shinier than in males.
Etymology. Oreads are Greek mythological mountain nymphs.
Differential diagnosis. Superficially similar to species from the M. minutus group but can be separated by the more oval body shape ( Fig. 19 View FIGURES 19–23 ) and by having a longer elytral stria 9.
Habitat and distribution. This species was collected in an isolated, mesic ravine (Armmanshoek) in the Vanderster Mountains in the Richtersveld National Park, South Africa ( Fig. 2). Mucina & Rutherford (2006) classify this area as the Stinkfonteinberge Quartzite Fynbos vegetation type. The soils are predominantly loamy. It receives approximately 200 mm rain per year. Coastal fogs occur between 10 and 20 days a year.
Remarks. Three specimens were sequenced for five gene regions (A, cytochrome oxidase I; B, 16S ribosomal RNA; C, 28S rRNA domain 2; D, 28S rRNA domain 3; and E, the CPSase region of CAD (carbamoyl–phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase)). The sequences can be found in GenBank (submitted by Sole & Scholtz 2010) with the following accession numbers: specimen 1, A: GQ290039 View Materials B:
GQ289687 View Materials C: GQ289821 View Materials D: GQ289905 View Materials E: GQ289974 View Materials ; specimen 2, A: GQ290040 View Materials B: GQ289688 View Materials C: GQ289822 View Materials D: GQ289906 View Materials E: no sequence; specimen 3, A: GQ290041 View Materials B: GQ289689 View Materials C: GQ289823 View Materials D: GQ289907 View Materials E: GQ289975 View Materials . A label with GenBank accession numbers has been added to each of the three specimens. Specimens were dissected during DNA extraction and are kept in ethanol.
