Diagnosis. Female can be recognised by the distinct colour patterns on body ( Fig. 17–19 View FIGURES 10–24 ); both sexes with infuscated bands on femora ( Figs 17–19 View FIGURES 10–24 ) and a band on tibia IV, epigyne atrium small, teardrop-shaped to oval, closed anteriorly ( Fig. 55 View FIGURES 43–56 ). Male with broad RTA base ( Fig. 53 View FIGURES 43–56 ); resemble M. irmatrix sp. n. but copulatory organs and colour of body and legs different.

Re-description. Female. Size, measurements (n = 5).

Carapace varies from mottled copper-brown to bright orange, copper-red or very dark copper, sometimes tinted with black, patterns and colour differ between individuals; clypeus either pale or with orange area extending onto cephalic area as a fine line; cheliceral tips may be dark; labium and mouth-parts dark; abdominal marks vary from dorsally uniformly pale to being decorated with a range of dark patterns ( Fig. 17 View FIGURES 10–24 ): a thin longitudinal central band, a big patch covering the anterior region and most of abdomen, or a longitudinal central band expanding laterally into two parts with or without small white patches within the darker band; abdomen ventrally very pale or yellow with metallic, dark blue or purple striae; metatarsi and/or tarsi IV or only tibia IV proximally dark.

Natural history. Specimens were sampled by beating and sweeping vegetation in grass- and wooded grasslands of coastal dune forests, they were also found near rivers and estuaries. Adults were sampled between October and January and juveniles in December.

Distribution. Namibia and South Africa (Eastern Cape Province, new record: KwaZulu-Natal Province) ( Fig. 118 View FIGURES 115–118 ).
