Holotype description. Holotype, ♂ ( Fig. 21 View FIGURES 19–23 ). Body length 8.8 mm, body width 6.2 mm.

Head. Genae sharp angled and sutures indistinct. Frontal suture distinct, angulate medially. Dorsal surface of clypeus rugose anterior of frontal suture, punctate posteriorly. Area between punctures shagreened.

Pronotum. Convex, anterior angles rounded, posterior angles rounded. Lateral border not punctate. Dorsal surface regularly punctate punctures close together, separated by less than one puncture diameter ( Figs. 80 View FIGURES 76–81 , 88 View FIGURES 88–93 ).

Elytra. Elytral interstriae 1–8 slightly raised, punctate, punctures shallow, punctures separated by 1–2 puncture diameters, each puncture with short associated seta. Elytral margins not carinate. Area between punctures shagreened. Striae clearly bordered, faintly shagreened, punctures very faint ( Fig. 98 View FIGURES 94–99 ). Stria 9 disjunct, anterior 1/5 medially between stria 8 and 10, second 2/3 very close to stria 10, interstria 10 almost covered by stria 9 in the anterior 1/3.

Aedeagus. The sclerite of internal sac elongate and strongly curved, without lateral process ( Fig. 38 View FIGURES 24–39 ).

Size range. Males length: 8.2–12.3 mm, width: 5.0–8.0 mm; females length: 10.0– 12.5 mm, width: 7.0– 8.1 mm.

Female. Beside the body length variations, female differs from male by having less developed frontoclypeal suture as well as the pronotal laterl marigins more clear in dorsal view than in male.

Etymology. This species is named after our colleague Prof. Catherine L. Sole of the Department Zoology and Entomology, University of Pretoria, in recognition of her leadership and her molecular work on the African dung beetles, lacewings and Baboon spiders.

Differential diagnosis. This species is most similar to M. nitidus and M. cederbergensis new species. It differs from the former in being more shagreened and less shiny on the elytral interstriae ( Fig. 98 View FIGURES 94–99 ) and from the latter by being larger and having the pronotal punctures smaller and farther apart ( Figs. 80 View FIGURES 76–81 , 88 View FIGURES 88–93 ).

Habitat and distribution. Cederberg Mountains ( Fig. 2). Specimens have been collected between 600 and 1000 m a.s.l. and mainly in the Swartruggens Quartzite Fynbos vegetation type. This area receives between 200– 620 mm of precipitation per year. The soils are sandy but skeletal ( Mucina & Rutherford 2006).

Remark. Frolov & Scholtz (2005) used specimens from this species for their redescription of M. nitidus . Please, refer to the redescription of M. nitidus for more detailed explanation.
